the ultimate guide to glass ballistic tests

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.

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
II-A 357 Magnum
II 357 Magnum JSP (higher velocity round)
9mm FMJ (higher velocity round)
III-A 44 Magnum, Lead SWC Gas Checked
9mm FMJ
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

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.

How Can Buildings Reduce Window Heat

Window film is one of the most efficient and cost-effective ways to reduce heat in your home or office building. Not only do window films save you time and money, but they also benefit the environment — while increasing  the aesthetic value of your building. 

Professional installation of high-quality heat reduction window films doesn’t have to be complicated. First, the correct 3M window film product needs to be recommended by a certified dealer, like Window Film Depot.  In this post, we’ve compiled the basic science of window heat transfer, the most effective ways to reduce window heat, plus five excellent options for heat reduction window film that cater to residential and commercial properties alike.

Read on learn about:

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

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?

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

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.

dual reflective privacy window film

What is Dual-Reflective Window Film?

Read More

dual reflective privacy 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.

Privacy Window Film Installations

As the #1 3M Window Film installer in the nation, Window Film Depot offers several product solutions and professional installation services for your privacy needs.

As one of the most popular products for its range of benefits, 3M Solar Mirror Film is a good option for commercial applications that demand flexible and reflective film for both privacy and sun control. It is the ideal one-way mirror window film for day and night.

At Window Film Depot, we can help you choose and install the right mirror window film to suit your unique needs and aesthetic. Learn more about your options by calling 1-866-933-3456 or contact us online to get started.

photochromic electrochromic window film glazing

What is Electrochromic Glass vs Photochromic Glass?

Read More

photochromic electrochromic window film glazing

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.

Carbon Footprint Reduction Tips

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

Read More

Carbon Footprint Reduction Tips

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 State Carbon Footprint Reduction Initiatives

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 of 2019

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.

Local Law 97 Compliance Emissions Limits

berdo boston compliance

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.

Energy Benchmarking DC

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


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.


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.

How to Improve Building Envelope

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.

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

How To Remove Old Window Tint

How to Remove Old Window Tint from Residential and Commercial Buildings

How To Remove Old Window TintWindow tinting films offer privacy, UV protection, and energy efficiency, so they’re a popular window film solution. However, all window tint films have a lifespan and once they go bad, you’re left with bubbling, peeling, unattractive films that need to be removed and replaced.

Not all window films are created equal and some will go bad before others. A window tint’s lifespan depends on several factors: quality of the film itself, exposure to the elements, and the quality of installation. A professional installation can mean the difference between decades of savings or a few short years before the tint needs to be replaced.

Reasons to Remove Old Window Tint


Bubbling is caused by failing adhesive and poor installation methods. Many people will try peeling and reapplying the area that has bubbled, but this can make the situation worse. Unfortunately, once a film has bubbled, it needs to be fully replaced.


Over time, window tint will become an unappealing purplish color due to the breakdown of certain dyes in the window film. Discoloration also means the film has lost its UV blocking capabilities, so it should be replaced with a newer, effective window film.


Sometimes it’s just time for an upgrade. While your window film may not be failing, it could look dated and require replacement. This can be the most difficult situation for removal, though, because the adhesive will still be intact and much harder to remove.

How to Remove Baked on Window Film

When it comes to how to remove old window tint, there are several solutions out there that you can try yourself, or hire a professional team to perform for you. There are two aspects to window tint removal: removing the film itself and removing the adhesive.

If done appropriately, peeling the film off should be fairly easy. However, if done wrong you may end up with tiny bits of film left on the window that you’ll spend lots of time peeling and scraping at. If possible, you want to pull off the film in large chunks.

Removing window film adhesive takes time and effort. The goal is to have as much of the adhesive come off with the window film as possible. Then you’re left with a minimal sticky mess that will take elbow grease and solvents to remove.

After the film and adhesive have been removed, you will need to thoroughly clean the window before installing a new film. Any bits of dirt or adhesive that remain can cause bubbles and other issues.

The primary method of removal involves using heat to break down the window film adhesive so that the remaining tint can be peeled off. There are several tools you can use to accomplish this method and it is often seen as the easiest way to remove window tint. Use the heat starting at the corner of the window and as it starts to peel, heat new areas of adhesive to loosen it up.


You can use a steamer to remove window tint and this is often seen as one of the quickest and easiest ways to do it. If you don’t have a steamer available, one can be rented. Use the steamer on both the interior and exterior (if possible) of the window to loosen the film and peel it away. This will also soften the adhesive, making it easier to remove film and glue at the same time.

Heat Guns

Curious how to remove window tint with a heat gun? Similar to using a steamer, the heat gun should be used on both the interior and exterior of the window to break down the adhesive. Once this is done, you should be able to pull the film off and scrape away any remaining adhesive with the tools below.

How to Remove Window Film Adhesive From Glass


Once you’ve used one of the above methods to remove the film itself, you can use a solvent to remove window tint glue. Acetone, isopropyl alcohol, or a window film adhesive remover are all very effective in breaking down the glue which can then be wiped or scraped off.


You can also use a specially formulated window tint removal spray to remove the glue residue. These can be purchased at home improvement or auto parts stores.


You may feel inclined to take a razor blade or sharp object to your window when you get down to the last bits of adhesive but use caution. It’s very easy to scratch the window if you don’t know what you’re doing. Once the window is scratched, there is nothing to do but replace it.

Removing Window Tint in Cold Weather

Since the main approach to removing window tint involves heat, it can be trickier to remove window tint in cold weather. You may struggle more to keep the adhesive soft in cold weather, but if you take your time and keep the heat gun or steamer close to the edge you’re peeling off, you should be fine.

Easiest Way to Remove Window Tint

We respect the DIY’ers out there, but window film removal and installation can easily be done wrong. Since installation plays such a huge role in the longevity of your window tint, we highly recommend hiring a team for professional installation. At Window Film Depot, we are ready to handle all of your residential and commercial window tint removal needs.

How to Burglar Proof Windows and Prevent Break Ins

How to Burglar Proof Windows and Prevent Break Ins

Burglars are opportunistic criminals and most of them won’t go to great lengths to get into a home. They take advantage of situations where it will be easy to make some quick money by stealing electronics, jewelry, or cash. Don’t let your home be an easy target. To prevent theft, creating burglar-proof windows and doors in your home will deter criminals from gaining entry.

While most burglars gain entry through doors, the second most common area susceptible to break-ins is first-floor windows. Second-floor windows are more difficult to reach and far less likely to be the source of a criminal’s attack. Fortunately, you have choices on how to prevent break-ins through your windows. There are several options available to you to reinforce security and keep your valuables safe.

How to Burglar-Proof Your Windows

Window Bars

Anti-Theft Window Bars

One of the simplest and most affordable solutions for how to burglar-proof windows is to install bars on the exterior of the windows. These bars keep would-be thieves from being able to gain access to the window to force it open or break the glass. However, window bars are obtrusive, and not many people want them to change the appearance of their homes. So what do you do if you want to prevent window break-ins without unsightly bars?

Window Security Films

3m Residential Safety Security Window Films

If you want to prevent window break-ins but can’t install bars, window security films are an affordable and visually appealing solution. These thin films, which are applied over your existing windows, are engineered to be tear-resistant and strengthen glass to prevent break-ins. They make the windows much more difficult to penetrate and slow burglars down, often enough to make them give up and move on to easier targets.

Additionally, these security films have other benefits that keep you and your family safe, like UV protection and protection from flying glass during natural disasters.

Window Locks

Secure Anti Theft Window LocksWhile it may seem obvious that you should lock your windows to keep burglars out, what you might not realize is that the locks that many windows come with are less than ideal and fairly easy for thieves to bypass.

There are numerous options available for secondary locks that can be installed to increase security on your windows. Pin locks are pins that slide into the window frame to keep it closed and track locks clip on the track of sliding windows and doors to keep them from opening.

These types of installations often have the added benefit of preventing children from opening windows from the inside as well, so kids stay in and burglars stay out.

Polycarbonate Safety Shields

defenselite unbreakable security glass windowsOne of the best ways to burglar-proof windows is to install polycarbonate safety shields, like DefenseLite, over your existing windows. Polycarbonate is 250 times stronger than glass and nearly impenetrable by would-be thieves. This option combines the low-profile appearance of security films with the performance of window bars to keep burglars at bay.

Unlike glass, when these polycarbonate panels are hit with blunt objects like crowbars or rocks, they flex with the impact and deflect energy away. Unable to break through these shields, most criminals give up and flee the scene leaving your windows intact and your valuables safe inside your home.

Motion Sensor Lights

Anti Theft Motion Sensor LightsWhile motion sensor lights aren’t an installation that can be applied directly to windows, they are a helpful way to deter criminals from even attempting to break in. Thieves target homes that have areas of low visibility, so neighbors and others nearby can’t spot them. If the exterior of your home is well-lit, burglars are less likely to see your home as a prime target.

Install floodlights with motion sensors at least ten feet high so burglars can’t reach them to disable them. When someone walks nearby, these lights will turn on and scare off anyone trying to access your home.

Security Cameras

Security camera and home in the eveningMuch like motion sensor lights, security cameras are an effective way to prevent criminals from even attempting to break into your home. Make sure security cameras are visible to make them the most effective since most criminals won’t bother with a home protected by security cameras.

However, some criminals are bold and will still attempt to burglarize your home with their faces covered. This is why it’s so important to protect your windows from burglars by reinforcing them with one of the options above.

How to Protect Windows from Burglars

As you can see, there are many options available for burglar-proofing windows. You can make upgrades to the window itself by installing films, locks, or polycarbonate shields or install deterrents to upgrade overall security with motion sensor floodlights and security cameras. Hopefully, you have some new ideas for how to upgrade your window security so you can leave your home with peace of mind, knowing your property is safe.

3 Types of Storefront Window Graphics for Function & Aesthetic

Window Graphics For Function and Aesthetic

Branding on storefront windows continues to be a highly effective marketing technique, attracting customers onto the premises with business promotions and appealing graphics. No matter the type of business you own, storefront window graphics are an essential tool for wayfinding, advertising, and promotional campaigns. Window graphics come in a variety of textures, colors, and capabilities that allow you to truly customize them to your business needs.

Below are three types of window graphics that offer both function and aesthetic to enhance your business’ storefront:

Perforated Window Graphics

Perforated window graphics transform your business’s windows and doors into prime advertising real estate.

These vinyl window graphics are made up of vinyl perforated with many tiny holes to create transparency. They can be used in a number of settings, and are typically ordered in ratios of vinyl holes to vinyl. 70/30 perforated vinyl window graphics are one of the most popular, made up of 70% vinyl material and 30% holes.

Since these see-through window graphics still allow for visibility from the inside, they can also be used as a form of privacy by creating one-way vision. While those outside see the graphic, those inside see through it to the street.

Sun Control Window Graphics

While advertising and branding tend to be the main reason to seek out business window graphics, there are additional benefits to installing these graphics on your business’s windows and doors. Sun control films can be custom printed with your business’s logo or promotional materials so that you get advertising and UV protection in one package.

Solve your heat and glare problem while also creating an interesting design element or advertising your brand. These UV protective window films maintain optimal visibility while still rejecting up to 97% of the sun’s dangerous rays.

Window Wraps

If you want to make an impact on your customers, commercial vinyl window wraps will help bring brand awareness. This particular type of window graphic is custom designed to be larger than life and displayed over a large commercial area.

If you have large windows and doors on your business, consider a large-scale window wrap with branded artwork to promote your latest sales and promotions while bringing awareness to your brand and attracting customers on-site.

These highly effective vinyl window graphics are custom designed and installed to your satisfaction.

Custom Window Graphics

For decades, the team at Window Film Depot has helped numerous businesses execute stunning and functional graphics to suit their needs. With our full-service production capabilities, our team manages the entire process, from site selection, city codes, to installation. We’ll custom design, print, and install wall graphics, building wraps, and perforated window films for your business.

Safety in the Workplace: 5 Tips for Creating a Healthy Environment

Read More

workplace safety healthy environmentThe safety and health of a workplace has a major effect on employee morale and productivity, and as the leader of your business or office, the responsibility of ensuring the health and safety of your employees falls on your shoulders. Especially now, during a pandemic, there is increased focus on healthy workplace initiatives. Fortunately, there are many ways to approach creating and improving a healthy work environment. 

A healthy workplace can include several aspects of the environment, from physical to mental wellbeing. We will be focusing on the physical workplace environment and the occupational health and safety of your employees. 

Work-related injury and illness can be costly, so remove yourself from liability and protect your employees from the start by investing in these simple yet effective ways to create a safe and healthy work environment:

1. Safe-Proof the Building

To avoid injury, the entire building should be inspected, and dangerous areas should be addressed. While this may seem overwhelming, this task can come down to a number of simple upgrades and adjustments to make the environment safer. This can include improvements like adding rubber padding along the ends of stairs, designating emergency exits, installing rubber mats at entryways to prevent slips and falls, and ensuring that railings are secure. 

Additionally, this can include making sure that all tools and equipment are installed properly and safely. For example, wires and electric cables should be covered or taped down to prevent employees from tripping over them. 

There are also areas that may require continued maintenance, like interior and exterior infrastructure. Walkways can become dangerous when icy, so make sure you have someone available to come and salt those walkways in the winter months. Additionally, for buildings that get a lot of sunlight exposure, UV-protected windows can improve occupant comfort while minimizing energy drain on heating and cooling systems.  

2. Use Signs and Graphics

Signage is an affordable yet effective way to remind employees of potential hazards and convey appropriate procedures to prevent injury and illness. Even for the most seasoned employees, this sort of information can be useful and preventative. 

These days, social distancing graphics and other visual reminders to maintain disease prevention protocols are necessary to creating a healthy work environment. This type of signage can help employees and customers maintain a safe distance from each other and also remind those entering the building to follow safety measures like wearing masks and sanitizing or washing hands. Once social distancing guidelines are lifted, they can easily be removed from windows, floors, and walls. 

3. Keep Things Clean

One of the key steps to maintaining healthy work environment standards is to ensure that your office or retail store stays clean. To prevent the spread of germs and disease, high-touch surfaces should regularly be sanitized, and frequent hand washing should be encouraged for employees.  

Businesses can further ensure the cleanliness of their space with technologies like NanoSeptic® self-cleaning surface films and PURE ZONE® antimicrobial films. Ideal for schools, airports, hotels, retailers, and restaurants, these films are applied on surfaces (i.e., door handles) and effectively reduce the transfer of bacteria and germs. These technologies are important investments in spaces where cleanliness is vital. 

A messy work environment can also lead to unnecessary injury. Make sure that all spills are cleaned up quickly and that tools and boxes stay organized and out of the right of way. Establish appropriate waste classifications, so employees and customers know where and how to dispose of food and other waste. 

4. Install Safety Shields 

Protect your employees by installing personal protective shields between desks or at registers and other areas where employees may interact with the public. Retail sneeze guards can prevent the spread of germs and disease, which is especially important now with the spread of COVID-19. These protective shields can be custom designed for your business and manufactured from a variety of materials, but polycarbonate shields are the most durable. 

Also, these shields can be installed between desks to keep employees safe from each other in office settings. They can be customized with additional benefits like cloaking privacy or switchable privacy to give employees privacy along with safety from the spread of germs. 

5. Apply Safety Films to Window & Door Glass

When glass windows and doors shatter, it can be a safety hazard, especially in the case of extreme weather and catastrophic events. One step you can take to improve the safety of your work environment is to install safety and security films on your building’s windows and doors. These transparent films are designed to hold broken glass together to prevent dangerous, sharp shards from forming when the glass is broken and, in turn, protect those inside. 

While these 5 steps are great ways to improve the safety of your workplace, one of the best things you can do to ensure a safe and healthy workplace environment is to encourage open communication with your employees. When they feel comfortable approaching you with an issue that makes them feel unsafe, or if they feel like safety standards are not being met, everyone benefits from the improvements made.
