School Security: How Window Films Are Transforming Educational Safety

FromFrom Legislation to Implementation: The New Era of School Security

Concerns over school security have reached unprecedented levels, prompting administrators and policymakers to reassess the protection of physical campuses.

With safety threats becoming more complex, the urgency to upgrade facilities is no longer a matter of preference. It is a necessity. In fact, among possible security threats, students believe school shootings are the biggest threat to their safety. Whether or not this is true is immaterial. Students who are preoccupied with security concerns are distracted, in danger of developing anxiety disorders, and have a harder time focusing on academics.

Among various solutions, security window films have emerged as a critical component of school security strategies.

These films, when integrated into a broader protection plan, can delay forced entry and improve emergency response time. Overall, this helps secure educational environments more effectively.

Technology Around School Security is Evolving to Better Mitigate Threats

Several high-profile school security breaches have shaken communities and exposed the flaws in outdated protection methods. These include violent incidents and unauthorized intrusions.

The resulting fear has driven a shift from reactive lockdowns to proactive architectural defenses. Schools are now emphasizing deterrence, delay, and rapid response. Instead of relying only on human behavior or emergency plans, many districts are taking physical measures.

Security upgrades like reinforced windows and doors are making schools more secure. These changes help schools become safer and more resilient to emerging threats.

Educational institutions are adopting a “hardening” strategy that uses physical upgrades to reduce vulnerabilities and improve emergency response times.

This includes reinforcing doors and windows with impact-resistant materials. Schools also apply security window films to delay forced entry. Electronic access control systems are added to monitor and limit who can enter the building. Surveillance cameras are installed to improve visibility and track movements on campus.

These systems work together to slow intruders and alert authorities. The goal is not to make schools feel like prisons. Instead, it’s about creating a multi-layered defense that reduces risks.

A well-designed plan can neutralize threats before they escalate. Delaying entry by even 30 seconds can be the difference between life and death.

Legislation Driving Change on the Federal and State Levels

Recent legislation shows a national push to strengthen school security. The Bipartisan Safer Communities Act, passed in 2022, is a key example. It opens new funding opportunities for physical security upgrades across U.S. schools.

Several states are also moving forward with mandates to support school safety, including but not limited to the following:

Texas: Requires security window films on all ground-level glass in schools
Georgia: Proposed $50 million in new funding for school security upgrades
Arkansas: Requested $50 million more to improve school safety systems
Montana: Mandated at least eight disaster drills to be held during the school year.
South Carolina: Allocated $20 million in school safety grants
Oklahoma and Illinois: Passed Alyssa’s Law, which requires school districts to implement a mobile panic alert system
Florida: Signed a bipartisan School Safety Bill, which includes the Office of Safe Schools to create a workgroup responsible for making recommendations to the Florida Institute of School Safety for improving statewide safety standards in educational settings
Tennessee: Approved $230 million for enhanced safety, including the investment of safety solutions
Minnesota: Implemented $3.1 million security upgrade plan for schools
Michigan: Passed a law in early 2025 with provisions aimed at increasing school safety

These laws show that policies alone do not secure schools. Physical deterrents must be implemented alongside rules to be effective. Schools with clear policies but no physical barriers remain vulnerable.

Security films, access controls, and reinforced doors are now essential tools. Legislation helps schools afford these upgrades through targeted funding and compliance requirements. Without legal backing, many districts delay or ignore necessary improvements.

Mandates make security changes standard, not optional. They push schools to act before an incident occurs. Laws also help unify safety expectations across districts and states.

The Grants and Financial Support Available to Help Make Schools Safer

Federal grants set national priorities and fund broad programs like training, mental health, and emergency systems. State programs support local needs.

Federal acts often cover policy development and preventive education. State grants fund building improvements like reinforced glass and surveillance equipment.

Together, these programs create a comprehensive safety net. Federal funding builds the framework. State support implements physical changes on campus. Both levels work together to help schools assess risks, apply solutions, and build safer learning environments for students and staff.

Many schools qualify for federal and state grants to enhance school security. These programs help fund critical safety upgrades.

The STOP School Violence Act supports threat assessments, crisis intervention teams, and school safety training. It also funds mental health programs. This grant improves communication systems and supports anonymous reporting systems for students and staff.
The Homeland Security Grant Program funds physical security enhancements for high-risk targets, including schools. It covers access control, surveillance, and protective glass systems.
Georgia’s HB18 School Security Grant provides $115 million for school safety projects. Eligible projects include reinforced glass, alarms, and secure entry systems.
Florida’s School Hardening Act allocates $42 million. Funds are used for perimeter fencing, security cameras, and forced-entry-resistant doors and windows.
Ohio’s K–12 School Safety Grant Program offers $215 million to public and private schools. It covers cameras, panic buttons, and glass protection films.

To access these funds, schools must submit timely applications with documented security needs. Grant applications must follow strict state or federal guidelines.

Districts benefit most by identifying specific risks and matching them to eligible expenses. Prepared schools secure funding faster and more often.

The Role of Security Window Films in School Safety

Security window films help glass stay intact when struck or broken. They add a protective layer to delay forced entry.

Criminals often break glass to gain quick access. Films slow them down by holding shattered glass in place. This delay can create valuable time for staff and first responders. It also deters intruders looking for fast entry.

Films allow natural light and visibility. Unlike bars or cages, they do not alter the appearance of the building. Schools retain a welcoming look while boosting protection.

Benefits of security window films:

Slows intruders during forced-entry attempts
Buys extra time for first responders to act
Maintains light and visibility without visual barriers
Costs less than full glass or structural replacements

Window films are not bulletproof. They do not stop gunfire or high-caliber rounds. They reduce access, not eliminate risk.

Schools that have installed security window films report better peace of mind. Installation is fast and minimally disruptive. Many schools can complete upgrades in a weekend.

Clear communication helps correct common misconceptions. When schools understand how films work, they use them more effectively in safety plans.

Real-Life Implementations

Round Rock Independent School District, Texas: This district invested nearly $250,000 in bullet-resistant window films for its elementary and middle schools. The aim was to enhance security by reinforcing vulnerable entry points like glass windows and doors.
Huron City Schools applied safety and security window film across its buildings to comply with Ohio’s Safety and Violence Education (SAVE) legislation. Superintendent Dr. James Tatman emphasized that the film enhances physical security while maintaining a welcoming environment. The film helps delay forced entry by holding broken glass in place, providing crucial time for emergency response. Dr. Tatman noted the film’s cost-effectiveness and minimal maintenance requirements.
A middle school in the Sandy Hook region implemented DefenseLite™, a security glazing system that outperforms traditional window films. This solution was chosen to fortify windows against forced entry, enhancing the school’s protective measures without compromising aesthetics.
Missouri Senate Bill 75 includes a new mandate for safety and security window film in public and charter schools. The bill requires film installation on glass entrances and first-floor windows to enhance student and staff protection. Governor Mike Parson signed the legislation, which passed with strong bipartisan support. Schools have until 2028 to complete the upgrades. State safety grants are available to help fund the required security improvements.
Dorchester School District Two received a $150,000 grant for school safety improvements. The funds will go toward installing shatter-resistant window film at multiple schools. This film is designed to hold glass in place during break-ins or attacks.

School Security Implementation Strategies

A strong school security plan needs more than a single product. Security window films are only one piece of the solution. These films delay intruders by holding broken glass in place. This adds time for staff to react and responders to arrive.

Major manufacturers like 3M clarify that window films are not bulletproof. They do not stop bullets or eliminate all risk. They are designed to delay entry, not to prevent it entirely. That delay can still be lifesaving in a crisis.

Some vendors exaggerate the films’ capabilities. Industry experts warn that demos may misrepresent real-life conditions, creating false confidence.

For maximum protection, films must be part of a full plan. Locked doors, monitored access points, and surveillance are also essential. Relying only on window film can leave other gaps exposed. A layered defense is more reliable and sustainable.

When integrated into broader strategies, window films become highly effective at buying time and reducing risk. Alone, they are not enough.

Best Practices for Physical Upgrades

Conducting a professional security assessment
Choosing the appropriate window film based on risk profile
Working with certified and experienced installers
Committing to regular maintenance and periodic evaluations

A layered security approach offers the highest level of protection. It combines physical security upgrades with strict behavioral protocols.

Physical upgrades include window films that slow intruders, secure doors that resist force, and electronic locks that limit access. These features delay unauthorized entry and alert staff.

Behavioral protocols include keeping all exterior doors locked during school hours, verifying visitor identity, and monitoring live surveillance feeds daily. These practices reduce human error and increase response time.

Schools should also establish internal communication systems for emergencies. Two-way radios, intercoms, and panic buttons can help staff coordinate fast responses.

Even the best tools fail without routine enforcement. Equipment must be maintained and staff must follow security procedures every day.

Security is only as strong as its weakest link. Window films add value, but ideally should be one component of a multi-faceted security plan.

Bottomline: window films alone do not stop attackers if other weaknesses—like unlocked doors or unmonitored entries—still exist. A holistic approach is essential.

Schools must ensure every layer of their safety strategy is enforced and maintained. While security window film solutions do not require regular upkeep, other security implements should be regularly checked.

A secure campus requires both physical deterrents and behavioral discipline. Security works best when every component supports the others. Only a coordinated strategy offers real, lasting protection for students and staff.

Final Thoughts: Creating Safer Schools Through Strategy and Support

In summary, the modern approach to school security requires both urgency and long-term planning. Schools must act quickly, but also wisely.

Security window films play a vital role in school hardening strategies. They provide scalable and cost-effective protection for vulnerable glass surfaces. By delaying forced entry, these films give staff time to respond and initiate lockdown procedures. Every second can save lives.

From an efficiency perspective, window films are also easy to install and minimally disruptive. They often require no structural changes, making them ideal for tight budgets. Because they preserve natural light and visibility, they maintain a welcoming school environment without sacrificing safety. That balance is critical.

Their value grows when combined with other layers of security like surveillance, door locking systems, and access control technologies. Window films represent both a physical barrier and a psychological deterrent, discouraging quick-entry attacks and giving first responders a head start.

Federal and State Funding Programs

School administrators and district leaders should actively explore grants, federal programs, and state-level initiatives to fund critical security upgrades.

This includes identifying which programs align with district needs, submitting applications early, and documenting vulnerabilities with clarity and evidence.

Collaboration with safety consultants or experienced vendors can streamline the grant process and maximize the return on funding opportunities.

With the right planning, schools can coordinate these resources to implement impactful improvements. Effective use of funding allows for timely upgrades. The result is a safer, more resilient learning environment. A place where students, educators, and staff feel supported, protected, and prepared for emergencies.

Cloaking film protects confidential information

Privacy Films: How to Protect Confidential Information in Workspaces

The Need for Visual Privacy

In today’s open-plan offices, transparency is not just an aesthetic choice—it is often synonymous with modernity, collaboration, and connectivity. Glass walls, expansive windows, and open floor plans dominate workplace design trends, offering daylight access, visual transparency, and fostering interaction. However, these same features also introduce new privacy vulnerabilities, particularly concerning the exposure of confidential information.

Organizations across industries are now tasked with finding a delicate balance between openness and confidentiality. As digital screens become ubiquitous—from HR workstations to patient intake areas—protecting visual data without compromising aesthetics or daylighting is a growing challenge. This article explores strategies to achieve that balance, with a focus on emerging cloaking film technology.

Where Privacy Matters Most

Visual privacy is not a one-size-fits-all concern. Certain work environments demand heightened attention due to the sensitive nature of the data, conversations, or transactions that occur within them. The consequences of insufficient privacy in these settings can range from minor discomfort to severe data breaches, regulatory violations, or reputational harm.
Conference Rooms and Executive Spaces

Conference rooms often serve as the nerve centers of strategic decision-making. Whether discussing financial forecasts, merger and acquisition strategies, intellectual property, or personnel matters, information shared in these rooms is often proprietary or confidential.

In conference room design, untreated glass walls present the risk of exposing digital presentations, video calls, or written notes.
Protecting these spaces from visual data leakage is essential to maintaining corporate confidentiality and avoiding information theft or competitive disadvantage.

Human Resources Departments

HR handles a wide range of sensitive information, including employee files and payroll, as well as discussions related to hiring, firing, and workplace grievances. Privacy breaches can erode employee trust, compromise personal data, and expose organizations to legal actions. Ensuring private conversations and screen content are visible only to authorized individuals creates a safe and compliant workplace culture.

Legal, Financial, and Compliance Offices

Legal and financial teams routinely process documents containing personally identifiable information (PII), contractual details, financial reports, and other confidential information that require discretion.

Inadvertent exposure of such information can violate confidentiality agreements, lead to data breaches or leaks, or result in compliance penalties under relevant regulations. Companies need to be cognizant of policies such as General Data Protection Regulation (GDPR) or the Sarbanes-Oxley Act (SOX). Visual privacy solutions support these teams by enabling transparency in office design while safeguarding sensitive content from wandering eyes.

Healthcare Facilities and Patient Intake Areas

Privacy in healthcare settings is more than a courtesy—it is a compliance imperative under HIPAA (Health Insurance Portability and Accountability Act). Patient intake desks, consultation rooms, and nursing stations are often designed with glass partitions for infection control and visibility. These must also protect medical records, test results, and private conversations from being seen or overheard by unauthorized individuals.

Visual privacy enhancements help healthcare providers ensure patients feel secure, respected, and protected.

Educational Institutions and Testing Centers

Schools, universities, and testing facilities manage sensitive student records, financial aid documents, and test results. In testing centers, the integrity of exams depends on strict visual privacy protocols to prevent cheating or information leaks.

Student counseling offices also require discretion to protect personal disclosures. Implementing privacy solutions helps educational institutions support both academic integrity and the emotional well-being of their students.

Financial Services and Banking Environments

In banking centers and financial offices, both customers and employees expect privacy for account details, investment discussions, and transactions.
Glass teller windows, consultation booths, and ATM areas are vulnerable to visual hacking or shoulder surfing. Shoulder surfing occurs in situations where sensitive information is observed without knowledge or consent.

Incorporating window film privacy solutions ensures compliance with GLBA (Gramm-Leach-Bliley Act) and provides clients with peace of mind.

Government, Defense, and Technology Sectors

Government buildings, defense contractors, and technology firms frequently handle classified or proprietary information, making visual privacy non-negotiable.

In these sectors, protecting on-screen data from leaks is crucial for national security, intellectual property protection, and operational integrity.

Cloaking films are particularly effective in these environments, allowing teams to work in open, collaborative settings without compromising data confidentiality.

Design Challenges in Modern Workspaces

The evolution of office design over the past two decades has centered on promoting transparency, fostering collaboration, and enhancing wellness. From floor-to-ceiling glass walls to open-plan workstations, these environments foster connectivity, increase natural light exposure, and create inviting spaces.

However, the architectural shift toward openness has introduced privacy and acoustic challenges that can affect productivity, comfort, and data security.

The Demand for Glass and Open-Plan Layouts

Glass has become the dominant material in contemporary design, both as an exterior facade and as an interior partitioning element. Glass walls and panels offer a sleek, modern, open look while maximizing the flow of daylight.

In parallel, the open-office concept has been embraced to promote collaboration, break down hierarchical barriers, and encourage spontaneous interactions.

Despite these advantages, the heavy use of glass and open-plan spaces creates unavoidable privacy pain points. This is especially true when sensitive work or conversations occur in visually exposed environments.

Balancing Transparency and Privacy

Designing spaces that are both transparent and private is inherently paradoxical. Clients and architects often seek solutions that allow glass to maintain its aesthetic benefits while also ensuring confidentiality.

Striking this balance requires innovative approaches that can deliver selective privacy without resorting to complete visual obstruction. For instance, solid walls or opaque coverings would undermine the design intent in these spaces.

Common Privacy Pain Points in Offices and Institutions

Several recurring issues are observed in modern office and institutional settings:

• Screen Visibility from Public Areas: In glass-fronted conference rooms or open workstations, digital screens are often visible, exposing sensitive data to unauthorized eyes.

• Lack of Acoustic Privacy: Open spaces combined with hard glass surfaces amplify sound, making private conversations easy to overhear.

• Daylight Management Conflicts: The use of opaque films or blinds can block natural light, negatively affecting occupant comfort, circadian rhythms, and energy efficiency.

• Employee Discomfort and Stress: Lack of visual and acoustic privacy contributes to employee dissatisfaction, stress, and reduced concentration, particularly in high-focus or confidential roles.

• Visual Clutter and Overcompensation: To regain privacy, some offices install ad hoc solutions, such as blinds, curtains, or temporary panels. These solutions can disrupt the clean, modern aesthetic of the workspace and create visual clutter.

Compliance and Regulatory Considerations

Many industries face strict data privacy regulations that require visual and acoustic privacy measures. Organizations must ensure that sensitive information is not exposed in ways that could lead to non-compliance, litigation, or fines.

Meeting these obligations in spaces designed for openness requires highly specialized products, such as cloaking films. These help bridge the gap between form and function.

Privacy Solutions for Glass Interiors

Organizations seeking to protect visual privacy in glass-dominated spaces have a range of solutions offering varying levels of effectiveness, aesthetics, and flexibility. While traditional methods still exist, recent technological advancements, such as cloaking films, provide a sophisticated solution that enables discretion and design continuity.

Frosted Window Film: Traditional Privacy Solutions:

Frosted window film, gradient, and other decorative films have been widely adopted as an easy-to-install method for obscuring views through glass.

Decorative window films can create an opaque or semi-opaque effect, effectively blocking visibility while allowing daylight to pass through.

Gradient films provide a more subtle approach by gradually transitioning from opaque to transparent in strategically placed areas.

Advantages:

• Affordable and easy to apply
• Enhances aesthetics with custom patterns or branded designs
• Allows for creative customization and zoning

Limitations:

• Obscures entire glass panels or large areas of the panels
• Reduces exterior views and may contribute to feeling enclosed

Smart Glass and Switchable Films

Smart glass and switchable films like Gauzy Smart Glass allow glass panels to change. The glass literally goes from transparent to opaque at the push of a button. This dynamic solution is ideal for spaces that require both openness and privacy on demand.

Advantages:

• Instantly switchable from transparent to translucent or opaque
• Supports multi-use spaces
• Enhances tech-forward aesthetics

Limitations:

• Higher upfront cost
• Requires electrical wiring and controls
• Fully obscures glass when activated, blocking views and daylight

Strategic Interior Layouts and Privacy Screens

Physical layout changes, such as installing privacy screens, adjusting furniture positioning, or placing planters, can shield screens or conversations from public view.

Advantages:

• Non-intrusive, flexible, and cost-effective
• Can be moved or adjusted as needed

Limitations:

• Limited effectiveness in fully open areas
• Does not address digital screen visibility through glass

Cloaking Films: The Modern Solution for Selective Visual Privacy

Cloaking films, such as Casper Cloaking Technology by Designtex, represent a revolutionary approach to visual privacy. Rather than obscuring the entire glass surface, cloaking film targets and selectively blocks the light emitted by LED and LCD digital screens. To outside viewers, these screens appear blacked out, while the glass remains fully transparent for other views.

What sets cloaking film apart is its ability to work in harmony with laminated or insulated glass configurations. When applied to laminated glass containing a PVB (polyvinyl butyral) interlayer, cloaking film does more than address visual privacy.

It also contributes to acoustic control by absorbing sound vibrations. This multi-functional approach is especially beneficial in environments where both speech and data privacy are critical.

When combined into an insulating glass unit (IGU), laminated glass with cloaking film delivers enhanced thermal, acoustic, and privacy performance. Sustainability and wellness goals are well within reach.

How Cloaking Film Works and Where to Use It
The Science Behind Cloaking Film

Cloaking film uses advanced nanotechnology to filter specific LED and LCD light frequencies. This makes digital displays invisible to outside observers.
It selectively blocks light wavelengths between 400 to 500 nanometers, rendering screens blacked out from the opposite side of the treated glass.

Other visual elements remain unaffected. People, objects, and backgrounds continue to appear normally through the treated glass.

This allows organizations to protect sensitive data without sacrificing the openness, daylight, or aesthetics provided by glass environments.

Ideal Applications for Cloaking Film

Cloaking film is ideal for spaces where confidentiality and transparency must coexist. These include:

• Boardrooms and Executive Suites: Protect presentations, financial data, and sensitive conversations from visual leaks during meetings.

• Hospitals and Healthcare Facilities: Shield patient information at reception areas, nursing stations, and administrative desks, ensuring HIPAA compliance.

• Government and Defense Offices: Protect classified or confidential information in mission-critical environments.

• Technology Companies and R&D Labs: Prevent intellectual property exposure and protect prototype development data.

• Corporate Lobbies and Co-working Spaces: Maintain a transparent, modern design while preventing accidental data breaches from visible screens.

Before-and-After Demonstration

For a compelling example of how Casper Cloaking Film transforms glass interiors, see the before-and-after video demonstration.

The video illustrates how digital content becomes invisible to outside viewers while the surrounding space retains full openness and transparency.

Key Benefits of Visual Privacy Enhancements

Investing in visual privacy solutions delivers measurable benefits beyond aesthetics. These include data protection, improved employee comfort, and regulatory compliance.

Protects Confidential Data and Conversations

Cloaking film prevents unauthorized visibility of sensitive digital content. This supports workplace confidentiality for meetings, transactions, and personal discussions.

Employees can engage in open conversations without concern for eavesdropping or screen snooping from passersby or guests.

This protection helps organizations meet privacy laws such as HIPAA, GDPR, and FERPA, reducing potential liability risks.

Enhances Professional Atmosphere and Comfort

Employees feel more secure and respected in environments where privacy controls are visible and effective.

This supports higher job satisfaction, better concentration, and improved trust between clients, employees, and leadership teams.

Customers and visitors also perceive businesses as more professional and considerate of sensitive interactions.

Maintains Daylighting and Design Continuity

Unlike frosted window films, privacy window films, or blinds, cloaking film preserves open sightlines and daylighting.

This enhances occupant well-being by maintaining views and natural light, which supports circadian health and productivity.

Design aesthetics remain clean, modern, and uncluttered, supporting brand identity and architectural goals.

Supports Compliance and Industry Regulations

Many industries require organizations to protect sensitive data under strict regulations. Cloaking film helps meet these obligations cost-effectively.

Visual privacy solutions support HIPAA in healthcare, GDPR in global operations, and PCI DSS in financial services.

By adopting these technologies, organizations mitigate risks of non-compliance, data leaks, and reputational damage.

Cost-Effective and Non-Disruptive

Installing cloaking film is a cost-effective retrofit solution. It requires no glass replacement or disruptive construction.

Organizations can upgrade privacy in hours, not days, keeping business operations uninterrupted and preserving existing interiors.

This allows businesses to enhance privacy standards and protect confidential information while maintaining budget and project timelines.

Strike the Perfect Balance Between Privacy and Design

As open-plan environments continue to define modern workspaces, addressing privacy challenges becomes an essential part of design strategy.

Cloaking film represents a powerful, design-forward solution for organizations looking to protect confidential data while preserving transparency, daylighting, and collaboration.

Facilities managers, architects, and business owners seeking to integrate these solutions can rely on Window Film Depot.

How Does Bulletproof Glass Work

The need for bulletproof glass in the United States is at an all-time high. In 2022, the FBI categorized 50 shootings as active shooter incidents — with additional types of gun-based crime, such as armed robberies, also plaguing the country. With such a need for the technology, many property-owners have begun to wonder: how does bulletproof glass actually work? Is it even really “bulletproof?”

We’ve got all of your questions answered. Dive into this comprehensive guide for a brief history of bulletproof glass, an explanation on how it works, and other important explanations when purchasing a solution.

- Ballistic Glass vs. Security Window Film
Common FAQs About Bulletproof Glass

- How Does Angle of Impact Affect Bulletproof Glass?

A Brief History of Bulletproof Glass

Like many great inventions, bulletproof glass was discovered by accident. In 1903, French painter, writer, and chemist Edouard Benedictus dropped a glass flask. Although the flask shattered upon impact, the glass shards remained together rather than spreading across the floor.

Upon examination, he discovered the flask was held together by a film, spurred by an alcohol solution of collodion. After a night of attempts to replicate the film, Benedictius created the first ever sheet of “safety glass” — sandwiching a film of cellulose nitrate between two sheets of untreated glass.

Through the years, Benedictus’s initial discovery has gone through continuous innovation and improvement, becoming widely accepted in diverse fields. From incorporation into warfare during both World Wars to its implementation on the PopeMobile, bulletproof glass is used across the world to protect those at risk from threats of active shooters.

Bulletproof or Bullet Resistant?

Don’t let the name fool you; no “bulletproof” glass solution is truly bulletproof. All bulletproof glass solutions are actually bullet resistant — designed to minimize the impact of bullets but not necessarily impenetrable. Bullets are incredibly high-impact, and can often be fired in rapid succession. In turn, even the strongest “bulletproof” solutions may break after enough rounds from a powerful enough firearm.

How Does Bulletproof Glass Work?

Bulletproof glass slows the impact of bullets by dispersing the kinetic energy of projectiles upon impact. When any surface is struck with a fast moving object, one of two things happens: the object shatters under the stress of force, or absorbs the impact as it spreads across the material. Glass, for example, has no means to absorb impact, thus shattering.

Bullet resistant glass solutions leverage several layers of protection to slow, then eventually stop, bullets upon impact. Take, for example, bulletproof glass made from laminated polycarbonate. With several layers of protection, bullets often get through multiple layers of protection, slowing to a point of stoppage before it fully penetrates the glass. Thanks to lamination, even penetrated layers stay together rather than falling into debris — both stopping bullets and protecting patrons from shatter.

What is Bullet Proof (Bullet Resistant) Glass Made Out Of?

There is no one thing that bullet resistant glass is made of; most types of “bulletproof glass” are composed of several materials, with multiple different variations of materials within the market as well. Some common & widely used types of bullet resistant glass include solid acrylic and laminated polycarbonate.

Solid Acrylic vs. Laminated Polycarbonate

Two of the most typical materials for bullet resistant glass are solid acrylic and laminated polycarbonate. Both are polymers — materials made from long lines of molecules chained together.

Polycarbonates refer to a group of thermoplastic polymers containing carbonate groups in their chemical structures. Installed as panels over existing glass or occasionally from scratch, polycarbonate solutions offer flexible installation for properties — alongside strength varying from UL 752 Level 1 through 8 per unique safety concerns. Polycarbonate powers several industry-leading bullet resistant glass solutions, including DefenseLite and BulletShield.

Acrylic, also known under brand names such as Plexiglas®, Perspex®, and Lucite®. Ranging in thickness from 1 ¼” to 1 ⅜”, acrylic comes in flexible sizes and is malleable to diverse installation needs. It resembles glass (with a transparency rate of 93%) while weighing 50% less than glass of equal thickness. Acrylic is less expensive than polycarbonate, and in turn is also less durable; even at maximum thickness, acrylic only meets UL 752 Level 1 requirements.

Ballistic Glass vs. Security Window Film

Often confused, ballistic glass and security window film are two different types of glass solutions. Although both provide impact resistance, ballistic glass and traditional security window film are made from different materials, both useful in separate situations. While security window film is excellent against most security threats, properties with specific concerns about bullet protection should opt for ballistic, bullet resistant glass.

Typically made from micro-layered, tear-resistant polyester film, security window film is designed to prevent break-ins, shatter protection, and smash & grab crime. The film absorbs the blunt impact of assailants, rather than shattering and allowing for easy access to a store. Meant to absorb blunt force, window film is not designed for the level of ballistic impact from a firearm. While window film may absorb some impact from bullets, UL-rated ballistic glass solutions are a better option for active shooter protection.

Common FAQs About Bulletproof Glass

With different materials and thicknesses to choose from, buyers of bulletproof glass have several key decisions to make before purchasing a solution for their property. Here are a few questions to consider, and our advice for purchasing.

How Thick Does Bulletproof Glass Need to Be?

The necessary thickness of bulletproof glass changes based on the unique security concerns of a residence or business; a store in a bustling city, for example, requires a different type of protection than an apartment building in the suburbs. Most bullet resistant glass solutions, such as BulletShield, are available in multiple thicknesses, customized based on the unique needs of a given property.

Additionally, thickness needs to change based on the type of material being used; because they’re different materials, one thickness of acrylic will have different protection than the same thickness in laminated polycarbonate. We recommend consulting a bulletproof glass installation professional to determine the exact thickness required for your security concerns.

How Does Angle of Impact Affect Bulletproof Glass?

Angle of impact greatly affects the damage done by a bullet; the smaller the angle, the more material a bullet has to pass through before reaching the other side. For example, a bullet approaching a vertical window at 90° has far less material to penetrate than one approaching at a 30° angle.

In turn, angled windows may need less thick glass to deliver the same level of protection from active shooters. To determine how angle of impact will affect the bullet resistance of your glass, contact a security window installation expert.

What is Sun Control Film?

Sun control film is a type of window film used for the specific purpose of minimizing the heat and UV effects of the sun through glass windows. It has immense benefits for both commercial and residential properties, increasing cost efficiency and creating more comfortable interiors for both residents and guests.

Thanks to its construction, sun control window film serves as an energy saver by reducing the amount of solar heat transmission. It acts by absorbing solar through the glass and limits the effect of the harsh sunlight on the occupants of a building — keeping buildings cool and reducing the amount of air conditioning needed. 3M Sun Control films come in different forms, depending on the needs of the building, and can be enjoyed in clear film without changing the look of the building.

When Is the Best Time to Install Window Film for Sun Control & Summer Energy Savings?

There is no one best time to install window film — any installation will provide significant benefits, lasting through the year’s remaining seasons and beyond. 3M Window Films offer a graceful, yet pragmatic way for working out several intriguing prospects of finagling sun control and security issues for your home or business not only in the summer, but also during winter months as well.

As we approach fall, the sun begins to enter buildings through the southern direction. This shift will angle some rooms in your home or business to develop a larger amount of daily sun, potentially impacting residents, employees, and guests with sensitive skin. Sun control films can diminish these negative effects, offering a near seamless solution to increased exposure.

Can Sun Control Films Save Energy?

Sun Control Films provide substantial heat rejection, creating energy savings for office buildings, retail stores, commercial and residential properties. Our film allows for the natural light to come in and offer high visible light transmission while the infrared rejection (up to 97%) provides significant savings and enhanced comfort. Up to 60% of the heat is rejected adding up to lower utility bills and higher energy savings. The best film choice to save energy depends on your goal and building structure — we typically recommend the 3M Prestige Series.

The 3M Prestige Series will let in the light but not the heat, creating superior comfort and clarity. The clear heat control films are designed for minimal aesthetic change to windows while providing maximum solar control performance. This current Window Film Depot project with 3M Prestige Film blocks 50% of the solar energy without altering the look of the building.

How Long Does Solar Film Last?

Typically, solar window film lasts around 10 to 15 years, but has the potential to last over 20. Quality of material and window film care are the two biggest factors impacting the longevity of window film; high quality products such as 3M Window Film last longer than lower quality options, while regular cleaning using non-abrasive supplies will help film last well into its expected lifecycle.

Most window film comes with a warranty ensuring replacement or repair within a certain window. At Window Film Depot, our 3M Window Film offers a lifetime warranty for residential applications, alongside a 10-15 year commercial warranty.

Does Clear UV Film Reduce Heat?

Clear UV film significantly reduces heat within interiors, offering immense temperature control benefits to both residential and commercial properties. The film serves as an energy saver by reducing the amount of solar heat transmission, absorbing solar through the glass and limiting the effect of the harsh sunlight on the occupants of a building.

Additionally, most clear 3M window films are protected with an abrasion resistant coat that provides long-term durability and makes maintenance easier. Our clear film offerings are durable, long-lasting, and highly effective at reducing heat.

How Can You Remove Sun Control Film From Glass?

Removing sun control film from glass requires two main steps — first removing the film itself, and then removing the adhesive. Generally, film removal is the easiest step of the process, while removing excess adhesive takes additional time and effort. Ideally, most adhesive will come off while removing the film to minimize additional stick left on your glass.

Sun control film removal typically involves the application of heat to break down enough adhesive for the remaining film to be peeled off. Both steamers and heat guns provide quick and easy ways to slowly peel off film. For more on window film removal from glass, check out our comprehensive guide.

Can I Install a Tinted Film on My Skylights?

Yes, you can install tinted window film in your skylights. Sun control film offers extensive benefits for skylights, including indoor temperature control, anti-glare capabilities, weather reinforcement, and prevention of furniture fading. Skylights are known for their architectural beauty, while also creating some interior problems; tinting can mitigate many of these issues.

Sun control film installation for skylights is similar to any other kind of window film installation — just at a slightly different angle. As with all window film installation, our powerful adhesion ensures our film remains in place.

How to Fix Sun Control Film on Glass

While easy to install (especially with the help of one of our expert installation teams), occasionally sun control film may peel or curl around the edges, or bubble amidst the middle. While bubbling may be fixable, once window film curls it means the adhesive has begun wearing off — requiring entirely new film.

Thankfully, skilled installation will greatly reduce the chances of your window film peeling, curling, or bubbling. Additionally, as mentioned early, most window films come with an extensive warranty; if your installation fails, we’re here to help fix the problem or replace the film entirely.

The Ultimate Guide to Glass Ballistic Tests: UL752, NIJ, NGA ASTM F3561, & EN 1063 Standards

Property crime is a major problem in the United States, with over 6 million reported cases in 2021 alone. To keep their homes & businesses safe, property-owners need to install durable glass security resistance. Yet with so many options available for window security, how can a property-owner tell if a solution is durable enough for their windows & doors?

Glass ballistic standards exist to give property-owners a specific, regulated look at a security solution’s durability to ballistic impact. In this comprehensive guide, we’ll dig into glass ballistic tests, different types of ballistic standards, and some key frequently asked questions.

Different Types of Ballistic Testing Standards for Glass
Frequently Asked Questions About Ballistic Impact Testing

What are Glass Ballistic Tests?

Glass ballistic tests are tests specifically designed to test the durability of bullet resistant glass solutions. Through these tests, regulatory agencies can determine just how resistant glass is, and apply a specific rating to tell consumers how one type of resistant glass compares to another.

Glass ballistic tests determine rating levels by firing a number of rounds into glass, while additionally noting the size of the weapon used to shoot the glass. To reach the best rating, the entirety of a bullet resistant glass system must absorb the force from the highest force of projectile — including glazing material, frame, and anchors.

Ultimately, glass ballistic tests sort bullet resistant glass into ratings within accepted standards created by different regulatory agencies. Each of these standards have different methodologies, offering a variety of methods to determine what impact-resistance a solution provides.

Different Types of Ballistic Testing Standards for Glass

While there are a variety of ballistic testing standards for glass, three of the most commonly used are UL752, NIJ 0101.06, and EN 1063. Here are brief summaries of each, alongside the standards themselves.

UL752 Ballistic Standards

The Underwriter’s Laboratory (UL), now known as UL Solutions, is a non-profit, global safety science company — the largest and oldest independent testing laboratory in the United States. Rating products in over 100 countries, UL Solutions tests a diverse suite of technology for safety standards, including bullet resistant glass. To be rated for a protection level, glazing must both not be penetrated by shots and resist all spalling at various temperatures.

The UL Ballistic Standard has 8 levels, tested as follows:

Protection Level	Ammunition	No. of Shots
Level 1	9mm Full Metal Copper Jacket with 3. Lead Core	3
Level 2	357 Magnum Jacketed Lead Soft Point 3.	3
Level 3	44 Magnum Lead Semi-Wadcutter 3. Gas Checked	3
Level 4	30 Caliber Rifle Lead Core Soft Point (.30-06 caliber)	1
Level 5	7.62mm Rifle Lead Core Full Metal Copper 1 Jacket, Military Ball (.308 caliber)	1
Level 6	9mm Full Metal Copper Jacket with 5 Lead Core	5
Level 7	5.56mm Rifle Full Metal Copper Jacket with 5 Lead Core (223 caliber)	5
Level 8	7.62mm Rifle Lead Core Full Metal Copper	5

NIJ Ballistic Standards

The National Institute of Justice (NIJ) is the research, development, and evaluation agency of the United States Department of Justice (DOJ). Although mostly known for its body armor standard (NIJ Standard 0101.06), the NIJ also has a standard for ballistic materials (NIJ Standard 0108.01). NIJ standards exclusively test whether or not a bullet penetrates a glazing.

The NIJ has four main levels and two sub-levels for a total of six rankings. They are as follows:

Armor Type	Test Ammunition	RQD. Hits Per Specimen
I	LRHW Lead 38 Special RN Lead	5
II-A	357 Magnum JSP 9mm FMJ	5
II	357 Magnum JSP (higher velocity round) 9mm FMJ (higher velocity round)	5
III-A	44 Magnum, Lead SWC Gas Checked 9mm FMJ	5
III	7.62mm, 308Winchester FMJ	5
IV	30-06 AP	1

EN 1063 Ballistic Standards

EN 1063, also known as CEN 1063, is a security glazing standard to measure the protective strength of bullet-resistant glass created by the European Committee for Standardization (also known abbreviated as CEN). The committee brings together the standardization bodies of 34 European countries.

The standard incorporates seven standard threat levels for fire from small arms, alongside two classes dedicated exclusively to shotgun blast. Similar to UL752 standards, EN 1063 are rated for both penetration and spalling.

Here are the full qualifications for each level of the EN 1063 standard.

Class Type	Test Ammunition	No. of Shots
BR1	.22 LR (L/RN)	3
BR2	.9mm Luger (FJ1/RN/SC)	3
BR3	.357 Magnum (FJ1/CB/SC)	3
BR4	.44 Rem Magnum (FJ2/FN/SC)	3
BR5	5.56×45 (FJ2/PB.SCP1)	3
BR6	7.62×51 (FJ1/PB/SC)	3
BR7	7.62×51 (FJ2/PB/HC1)	3
SG1	12/70 (Solid Slug 3)	1
SG2	12/70 (Solid Slug 3)	3

NGA ASTM F3561 Standard

Known for developing new testing standards in response to expanding parts of the glass industry, the National Glass Association (NGA) is the largest trade association within the field, comprising 1,700 member companies. As school shootings have risen across the United States, protection from active shooters has become a major area of importance for the association.

Following an eight-month, multi-step review process, the NGA developed the “Standard Test Method for Forced-Entry-Resistance of Fenestration Systems After Simulated Active Shooter Attack.” According to its website, this standard will “promote the use of glazing for visual awareness and entry deterrent in a meaningful way to address the risk, threats and vulnerabilities of educational facilities.”

Unlike previous standards mentioned above, the ASTM F3561 standard does not test for complete ballistic resistance; instead, it evaluates the ability to create an opening sufficient size to permit passage of a test shape through it. The procedures are as follows:

10 ballistic rounds from a single weapon and ammunition type are fired into the glazing products in a tight burst
The weapon that must be used in the testing is the AR-15 with 5.56x45mm ammunition, as it is the most commonly used weapon in school shooting attacks
Following the initial weakening from the ballistic assault, the glazing is then struck with a center-mass, 100-pound mechanical impactor at eight different drop heights

Frequently Asked Questions About Ballistic Impact Testing

How are Ballistics Tests Performed?

Glass ballistic tests consist of firing a number of rounds into glass to test if a glazing can withstand that specific level and volume of impact. Ratings are achieved based on which level of impact resistance the glazing sustains — changing based on number of rounds fired, types of rounds, distance between firing, and velocity of a shot. Between firing every round, the tester will check if a glazing has been penetrated.

How Does Ballistic Testing Work?

Ballistic testing is usually conducted by a dedicated materials lab trained in testing for a specific ballistic standard. Once rounds are fired during testing, scientists will check to see how the rounds affected the glazing. Depending on the standards, glazing will be judged based on whether or not the bullets fully penetrate glass, or if they spalled (spread dangerous flying debris due to impact). This process is then repeated varying amounts of time depending on the testing standard.

How Long Does a Ballistic Test Take?

Generally, as a test only consists of a few rounds being fired, an actual ballistic test won’t take more than a day. However, due to multiple rounds of testing, set-up for testing, processing, product delivery, and back-log within laboratories, the length of time to hear back about a ballistic test will vary. If waiting for the results of ballistic testing, contact appropriate laboratories for accurates finish times.

How do EN1063 Standards Compare to UL752 Standards for Glazings?

EN 1063 standards and UL753 standards are similar in that both require glazing to both withstand penetration and prevent spalling. Generally, however, UL752 testing is more thorough, requiring multiple samples tested at diverse temperatures (while EN 1063 is only tested at ambient temperature). Additionally, the two standards test different types of ammunition for different levels. For specific differences in standards for each, see the charts listed anova.

How do NIJ Ballistic Standards Compare to UL752 Standards for Glazings?

While the NIJ standard can be useful, the UL752 standard is generally considered superior to NIJ 0108.01. UL standards look for both penetration of glazing and spalling, whereas the NIJ standard only considers complete perforation of a panel within rankings. In turn, UL752 offers a more nuanced, specific look at the strength of a glazing.

Understanding Window Heat Transfer

Generally, heat transfer occurs when there is a temperature difference between two objects or spaces, flowing from hot to cold. Heat transfer occurs in three ways:

Conduction: The movement of heat through a solid material.
Convection: The movement of heat due to the movement of fluid.
Radiation: The movement of heat through absorption, reflection, or transmission through electromagnetic waves, mainly in the infrared region.

Naturally, the rules of heat transfer also apply to windows. As interior spaces warm up in winter months, windows transfer heat outside; during hotter summer months, meanwhile, windows absorb heat, warming up air-conditioned spaces and forcing HVAC systems to work harder.

The effects of heat transfer can be extremely detrimental on home temperature costs. According to the Department of Energy, about 30% of a home’s heating energy is lost through windows, while about 76% of sunlight that falls on standard double-pane windows enters to become heat in cooling seasons. To increase heat reduction, property-owners have several options to apply to their windows.

Most Effective Ways to Reduce Window Heat

There are numerous options for property-owners looking to improve heat reduction properties within home or business. Popular options include weatherstripping, blackout blinds, and even insulating windows with bubble wrap. Two of the most popular opinions, however, are window shades and window film.

Heat Reduction Window Shades vs. Window Film

Heat reduction cellular shades are designed to fold up at the top or bottom of a window, allowing for retractable heat reduction. Traditionally, cellular shades also “shade” a room by obscuring light, offering additional control of natural light within a space.

Window film, meanwhile, is a more permanent solution that is applied onto existing windows. Once installed, window film stays in place throughout the year for consistent, constant window heat reduction. Aesthetically, window film comes in a wide range of opacities, from optically clear to tinted, depending on your property’s needs.

Because window film offers more flexible visibility while maintaining heat reduction, it exceeds window shades in terms of design capability. Temperature control window film can still allow nearly all of the natural light of a traditional window, or provide a tinted environment for properties looking for greater privacy. Adding shades or curtains to windows with film provides additional design flexibility without having to rely solely on them for heat reduction benefits.

How Well Does Temperature Control Window Film Work?

Professionally installed window film is scientifically proven to offer more powerful, consistent heat reduction than other methods. EFILM software models based on the Department of Energy’s standards to model a building before and after window film have shown 3M window film products to reduce up to 78% of the sun’s heat, leading to a net negative carbon impact within six months of installation.

Beyond heat reduction, installing window film can offer financial incentives for businesses. The recently passed Inflation Reduction Act made it so properties can gain tax credits for reducing emissions of Greenhouse Gasses and Hydrofluorocarbons. Utility companies in some cities even rebate the installation of window film by as much as 50% — making window film a clear financial choice.

Additionally, ConSol Energy and Environmental Solutions, a leading consulting firm for builders, government agencies, utilities, and trade associations, calculated the effects of adding window film to a commercial building. Their study found that temperature control window films installed on single-pane glass showed paybacks in as little as 1.4 years and provided an annual energy savings of 19 kWh/sq ft of glass.

Clearly, exterior window films offer a considerable amount of heat reduction and improved energy efficiency. They are an affordable solution compared to replacing entire windows and can be installed much more quickly with minimal interference in your day-to-day.

Window Heat Reduction Film Installation Options

There are quite a few heat reduction window film products available, but they can be broken down into two main categories: those that are installed inside and those installed outside. Both add an additional layer of heat reduction to your existing windows, essentially upgrading them from single-pane windows to double-pane windows, or double to triple.

Interior Installation with Window Heat Reduction Film Kits

This type of window film is applied to the inside of a home or office building. Film heat reduction kits include a large piece of shrink-wrapping plastic that can be cut to size and an adhesive material like tape or magnets which are used to secure the plastic film to the window frame. Once installed, a heating element like a hairdryer is applied to the plastic, which shrinks it to the correct size.

Window film heat reduction kits are one of the cheapest ways to increase heat reduction in your home. However, since they are installed inside, they can be unsightly – which is why many homeowners tend to steer clear of them. Window heat reduction kits need to be installed and removed every year with the change of the seasons. So, if you’re looking for short-term, one-season use, then they might work for you.

Exterior Installation with Retrofit Heat Reducing Window Films

These window films are made up of multiple layers of ultra-thin plastics which are applied with an adhesive to the exterior of existing window glass. Once installed, these films are nearly invisible unless you want to incorporate tinting or mirroring for privacy.

Because they are a permanent solution, these window films have the additional benefit of heat retention in the winter along with retaining cool air in the summer, so you get energy efficiency year-round.

They also provide UV blocking capabilities which will keep your furniture and merchandise from fading and prevent glare for those inside, making for a more comfortable environment overall.

What is Dual-Reflective Window Film?

Since natural light is so desirable in homes, office buildings, and retail spaces, the current trend is to install the biggest and most expansive windows possible. While they improve value and aesthetics, large windows do sacrifice privacy as onlookers can see straight into your building. Fortunately, there is a solution to your privacy issue: dual-reflective window film.

This type of reflective window film is designed to offer privacy during the day and reduce reflections at night. It’s called dual-reflective window film because both sides of the film offer benefits. The outside layer is designed to be highly reflective so that people outside can’t see in during the daytime and the inner layer helps to improve visual clarity at night.

Does reflective window film improve privacy?

The primary goal of reflective window films is to increase privacy for those inside. Plain glass with no reflectivity has high visibility from the inside and outside during the daytime. The shiny metallic surface of these types of window films reflects daylight and makes it difficult to see inside.

Dual-reflective window film at night won’t offer the same level of privacy though. Since there is no light reflecting off the metallic exterior surface, people will still be able to see in your home when it is dark outside.

Mirror Window Film vs. Dual-Reflective Window Film

How are reflective mirror window film and dual-reflective window film different? The answer is that they are very similar films. Both are designed to increase privacy, along with offering improved energy efficiency and UV protection.

The difference lies in the benefits offered by the interior layer of the film. Dual-reflective film has an interior layer with a less metallic surface which helps to improve nighttime visibility for people inside the building. This means that your views aren’t compromised by the installation of the film.

Mirror window films are a special type of one-way film that’s main focus is its privacy capabilities. The outside of mirror window films are highly reflective, or “mirror-like” to make it very difficult to see inside.

These window films do not have an interior finish to change the way the film is viewed from the inside but offer a clear, undistorted view from indoors. Mirror window films are a convenient and cost-efficient solution to convert windows into one-way privacy glass.

Advantages of Dual-Reflective Window Film

There are numerous benefits to installing privacy window films. Of course, the main advantage is its ability to reflect outside scenery, making it difficult to see inside. This increases privacy and security for people inside. This reflectivity can also reduce glare and improve views in both daytime and nighttime.

Another benefit is its ability to reflect solar heat which can improve comfort and also reduce energy costs. The building will be cooler overall, so your air conditioner will have less work to do in the hot summer months, saving you money on your energy bill.

Finally, dual-reflective window film blocks a large percentage of harmful UV light and rays. Not only does this prevent damage to your skin, but it also protects furnishings and hardwood floors from fading.

When to use Dual-Reflective Window Film

Dual-reflective privacy window film is most commonly used in commercial settings rather than residential ones because this type of film does change the appearance of the windows. Not only does it add a mirror-like effect to the windows, but it will also make them darker. This is why many people find other window films to be better for residential use.

In general, though, dual-reflective window film is best used in situations where privacy is needed during the daytime, but you want to maintain views at night. Maybe you have large windows that look out onto a skyline and want to still get those views once the sun has set. Dual-reflective films would be a great choice for you.

What is Electrochromic Glass vs Photochromic Glass?

Both electrochromic film and photochromic film are some of the industry’s most advanced dynamic glazing products offering transformational capabilities for your windows. However, these technologies are very different and offer varying benefits.

While one offers on-demand privacy, the other offers dynamic sun control. We’ll break down the technology behind these films so you can better understand which is right for you.

What is Smart Glass?

Smart glass refers to a variety of intelligent glass options with varying properties that can transition depending on circumstances and includes switchable smart film (smart tint) and switchable smart glass.

There are three types of smart glass: both electrochromic glass and photochromic glass fall into this smart glass category.

Some glass comes with photochromic or electrochromic technology already built-in. Alternatively, smart glass film can be applied to existing glass, giving it either electrochromic or photochromic capabilities.

Electrochromic Window Film

Electrochromic film, also known as electrochromic window tint or “switchable” film, is a unique product that turns windows from transparent to frosted or tinted on command. It can be used in a variety of installations, from interior to exterior, where on-demand privacy or sun protection is required.

Electrochromic is a word used to describe materials that can change color when energized by an electrical current. The electrochromic tint of electrochromic windows is controlled by the amount of voltage applied to the glass. At the press of a button, the voltage changes, causing a reaction within the electrons that changes the way it reflects light.

The main advantage of these smart glass windows is that you can directly control the switchable nature so that you can tint the window when needed but leave it transparent in other situations. This maximizes access to views and the desired amount of light, allowing design freedom and giving architects the ability to design without blinds or other window shades.

Electrochromic glazing is ideal in many situations but is often applied in interior installations on windows, doors, and glass walls to provide a dynamic layer of privacy. Commercial, government and educational buildings can all benefit from the use of switchable window films.

Additionally, this type of film can be used for exterior purposes to change the tint of windows on command. However, it often lacks the sun and temperature control capabilities that photochromic film delivers.

Photochromic Window Film

Another common name for photochromic film is “transitional” film. This type of film changes from clear to tinted when exposed to the sun’s UV rays through a chemical process within the glass. It adapts to the amount of sunlight to provide concentrated levels of sun protection, but only when it’s needed.

Photochromic glass truly is “smart glass” since it adapts on its own and doesn’t require electricity to power it. A popular photochromic film product is CoolVu transitional film, which blocks 99% of UV rays and reduces solar-induced heat by up to 80% while still maintaining your desired aesthetic. This built-in UV and heat blocking smart glass technology help save money on cooling costs, allowing buildings to run their air conditioning less. You get the same energy savings and light glare reduction as static tint films without unattractive metallic tint.

Electrochromic Window Film for your Building

While photochromic films are more beneficial for their sun control capabilities, electrically switchable electrochromic films are more appropriate in the context of privacy and when a certain aesthetic needs to be maintained.

Whatever your smart glass needs are, Window Film Depot is here to help. When it comes to deciding between electrochromic or photochromic window films, we can discuss with you what your needs are to help guide you to the best solution.

Improve Carbon Footprint & Reduce Energy Consumption in Commercial Buildings with 3M Window Film

With current and upcoming carbon footprint reduction mandates aimed to reduce greenhouse gas emissions, building owners, developers, and architects need a cost-effective solution to ensure compliance and avoid costly fines and penalties.

In addition to ensuring local and federal law compliance, there are many additional benefits of reducing carbon emissions from buildings. These include lower heating and cooling bills, lower electricity bills, and even funding and rebates available to buildings that have made these modifications.

Cities including New York City, Boston, and Washington DC have led the charge on carbon footprint reduction by mandating buildings to reduce and report their energy usage. These cities will be imposing fines and penalties as early as 2022 for non-compliance. With such a fast-approaching deadline, finding a fast, efficient, and cost-effective solution – like window film – will allow building owners to remain compliant without making significant changes to their building or systems.

What is Carbon Footprint Reduction?

Carbon footprint reduction is the practice of consuming less energy. According to a study by the U.S. Department of Energy, commercial and residential buildings combined consume nearly 40 percent of the total energy usage in the United States, more than both the industry and transportation sectors.

Today, there are more than 4.7 million commercial buildings in the United States alone.

With the recent carbon footprint reduction mandate put into action by the Biden administration, taking carbon footprint reduction measures is more important than ever. Biden’s 2030 greenhouse gas reduction target aims to reduce greenhouse gases by 50-52 percent by 2050 from the levels measured in 2005.

Part of this plan includes supporting energy efficiency upgrades in previously constructed buildings and adopting modern energy codes for new buildings. Finding a cost-effective solution for how to reduce CO2 emissions in buildings now will let owners and developers get ahead of expected state laws and legislation designed to support the greenhouse gas reduction target goals.

Federal and Local Carbon Footprint Reduction Initiatives

There are both Federal and Local carbon footprint reduction initiatives and laws that building owners and developers need to be aware of. Non-compliance with these initiatives can carry serious fines and penalties, making compliance crucial.

Federal Climate Policy 106

Federal Climate Policy 106 focuses on reducing carbon emissions in the building sector, which consists of both residential and commercial buildings in the United States. Without factoring in the use of electricity, the building sector accounts for 12.5 percent of the total greenhouse gas emissions in the U.S. This includes using fossil fuels for heating, cooling, and cooking.

However, once electricity usage is factored back into the equation, this number jumps to almost 40 percent. In other words, electricity usage in the building sector accounts for roughly 25 – 27 percent of greenhouse gasses in the country.

Building energy codes require new and renovated buildings to adopt energy efficiency features in their construction and design, and can include requirements for the building envelope (insulation, windows, walls, and roof), ventilation, cooling and heating systems, and lighting.

Making improvements to all of these elements can be costly, so finding a multi-purpose solution to address several of these elements at once can save builders and developers quite a bit of money.

NYC Local Law 97 & Climate Mobilization Act

In New York City, buildings account for about two-thirds of greenhouse gas emissions. In April 2019, the City Council passed the Climate Mobilization Act & Local Law 97. Both of these initiatives were part of Mayor de Blasio’s New York City Green New Deal, a systematic plan for the city to be carbon neutral by 2050.

Local Law 97 requires most buildings over 25,000 square feet to meet new greenhouse gas emissions and energy efficiency limits by 2024. Those limits will become stricter in 2030.

With only two years for NYC buildings to meet new energy standards, owners and developers need to quickly address these issues – or face fines and penalties if Local Law 97 compliance is not met.

Emissions Limits for Commercial Buildings in NYC

With emissions limits already being significantly reduced in New York City, understanding current and upcoming limits is an important part of implementing the right carbon footprint reduction methods that will make the most impact.

Boston’s Climate Action Plan

Buildings account for over 70% of greenhouse gas emissions in Boston. As part of the city of Boston’s Climate Action Plan, they introduced the Building Energy Reporting and Disclosure Ordinance. Also known as BERDO, the ordinance requires large- and medium-sized buildings to report both energy and water usage every year.

Additionally, buildings are also required to complete a major energy savings action or assessment every five years. BERDO Boston is public information and allows for easy benchmarking of commercial and residential buildings’ energy consumption and improvements.

Clean Energy Benchmarking in Washington DC

Clean Energy DC, signed into effect in 2017, is Washington DC’s climate and energy action plan that outlines the specific actions and steps that need to be taken to achieve tangible carbon reduction goals for the district.

The Clean Energy DC Plan aims to reduce emissions by 56% in 2032 compared to the baseline taken in 2005, similar to the plan set forth by the Biden administration. Washington DC’s sustainability plan outlines 57 concrete actions that need to be taken to achieve this goal.

Washington DC energy benchmarking for buildings has been required since 2008. But with the introduction of Clean Energy DC, there came the Building Energy Performance Standards (BEPS) that were outlined in the Clean Energy DC Omnibus Amendment Act of 2018. According to BEPS, buildings must maintain a minimum energy performance no lower than the local median ENERGY STAR score by property type.

Carbon Footprint Reduction Tips & Measures

Lighting

Installing or upgrading current lighting in existing buildings can help save energy and therefore reduce energy consumption. Upgrading all lightbulbs to LED bulbs is a good starting point. Another way to reduce your carbon footprint is to utilize solar power wherever possible. This can include outdoor lighting that uses solar boxes instead of traditional power sources.

HVAC

Improving the performance of your HVAC system can be expensive if you focus primarily on upgrading the system itself. However, by installing window film on all of the windows and doors of your building, you can improve the overall insulation of the building. In turn, this reduces the need for your HVAC system to run as frequently, which in turn reduces energy consumption and greenhouse gas emissions.

Insulating Glass Windows

Similar to HVAC systems, replacing or reinforcing all of the windows in a building is an expensive, disruptive and unsightly process that can take a long time to complete. Window film is a much more affordable, less disruptive option that won’t change the aesthetic of your building – unless you want it to! Installing window film adds an additional layer of protection and insulation to windows, and turns a single pane of glass into a double pane, and a double pane into a triple pane.

Renovations & Adaptive Reuse

Builders and developers can make a greater impact by making renovations to an existing building or practicing adaptive reuse. Instead of building a new small freestanding retail store, renovating an existing abandoned corner unit in an otherwise busy building will reduce the carbon footprint by eliminating the need for new construction and materials.

Similarly, adaptive reuse repurposes entire existing buildings, which in turn takes away the initial carbon emissions created during the construction process, allowing the development to participate in a circular economy.

Because of these laws and regulations, many new buildings are being constructed to be net-zero. Different from carbon-neutral buildings, which is when buildings significantly reduce their carbon emissions and then offset the rest, net-zero buildings produce on-site or utilize renewable, carbon-free energy to sustain building operations.

Reduce Emissions with Commercial Building Envelope Improvements

Improving the building envelope in an existing building is fairly easy when you take the right steps. The building envelope consists of the roof, windows, exterior doors and cladding, and is often overlooked when it comes to carbon footprint reduction. But improving the building envelope is a great way to reduce building emissions.

Implementing low-cost, high reward strategies, like using window film to improve the building envelope, will allow commercial buildings to monitor energy consumption and reduction over time without making a huge investment upfront.

Since window film is applied to glass windows and doors, it addresses two out of four of the elements of the building envelope.

Ways to Reduce Energy Consumption in Commercial Buildings Using Window Film

Making significant, complex improvements to large commercial buildings can be disruptive to tenants, take months – even years – to complete, and depending on the upgrade, can be quite costly.

In contrast, window film is an aesthetically pleasing, comparatively inexpensive solution for commercial buildings to reduce energy consumption.

Reduce HVAC Energy Costs

As we discussed earlier, 3M™ window film products can help reduce HVAC energy costs in commercial buildings. This is achieved in several ways.

Heat control films allow buildings to regulate moderate temperatures more effectively by rejecting UV rays and electromagnetic energy, eliminating the need for a drastically fluctuating thermostat.

Low E and insulating films provide both heat blocking technology and window insulation, retaining cool air during the summer and warm air during the winter. This reduces the reliance on an HVAC system to run more frequently during extreme temperatures.

Improve Window Insulation

Installing window film helps provide insulation, which is yet another way to improve your building envelope efficiency.

Window film turns single pane windows into double pane windows and double pane windows into triple-pane windows without the expense of adding actual glass to the window itself.

This added layer of protection and insulation helps reduce HVAC costs by helping keep heat in during cooler months and cool air during warmer months.

Not only is window film for commercial buildings a cost-effective way to improve your building envelope, but they also have additional benefits that other upgrades and improvements don’t.

Additional Benefits of Window Film

- Sun control and heat reduction benefits of window film don’t just improve building envelope efficiency, but also increase the comfort of tenants.
- UV blocking technology provides additional safety to tenants, equipment, and furnishings.
- Window film provides added window security and shatter protection to exterior glass
- Dark and reflective films allow buildings to update the look of their doors and windows
- Clear films like 3M™ Prestige provide sun control, climate control, and energy savings benefits without changing the appearance of glass for building owners who don’t wish to alter building appearances.
- Window film has no visual impact, allowing for easy approval from historical societies
- With 3M™ window film installation, labor and materials are warrantied by 3M™ Company for up to 15 years
- Certain states offer funding, rebates, and programs including LEED points and ENERGY STAR Portfolio Manager score increases
