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.

wfd texas school safety standards pr

ATLANTA, GEORGIA, January 31, 2023— Window Film Depot, a nationwide leader in security window film installations designed to mitigate active shooter incidents, is launching  initiatives to help Texas school systems meet the new safety standards set by the Texas Education Agency (TEA). These new standards are being implemented state-wide in response to the recent school shootings in the state.

The over-arching goal is to increase security for students and faculty by reinforcing vulnerable entry points, such as ground level window and door glass. Specifically, the revised School Safety Standards call for the application of access denial window film to these vulnerable areas with the intention to delay entry into a building through broken glass.

To facilitate these changes, the TEA has allocated $400 million dollars in grants for school districts, which will be available in February 2023. Specifically, this money is to “assist school districts in replacing or upgrading doors, windows, fencing, communications, and other safety measures.” Schools have until February 17, 2023 to apply.

With a looming deadline and the vast number of schools seeking to complete that grant application, Window Film Depot, the nation’s leader in 3M window safety and security window film, is working alongside 3M and Texas local education agencies (LEA) to expedite the procurement process for school administrators.

“Window Film Depot is a trusted resource for schools across the state as they focus on meeting these updated safety standards,” said Krissy Mosby, President of Window Film Depot. “There are many factors for school administrators to consider, and we aim to do our part to ensure that each school is both compliant with the new state-wide regulations and provided with the right solution for their particular building security needs.”

Through educational webinars reviewing product and grant information, and, in certain cases, on-site assessments to help schools ascertain their exact needs and find the right security solutions, Window Film Depot will help school officials evaluate the types of security window film and other solutions available, such as DefenseLite® and BulletShield®, for more robust protection. Window Film Depot’s safety assessments meet the TEA standard requirements. Provided estimates are free to school systems and guaranteed to meet the state deadlines imposed for grant funding.

Window Film Depot has a national footprint, with an office conveniently located in Dallas-Fort Worth to help facilitate the new safety standards in Texas. As such, free assessments are available to schools across the entire state. Assistance is provided to all schools to best determine their security glazing needs, identify vulnerable entry points, and develop accurate quotes based on site specific information.

“We encourage school officials and safety compliance professionals to utilize the resources we are offering to determine how best their Texas School Safety Grant should be allocated for maximum security,” said Donnie McDaniel, Director of Government Sales at Window Film Depot. “Our solutions have been tested to meet Homeland Security, FEMA, GSA, and the Department of Defense standards, and we will help each school determine its unique needs to make the upgrades that will help ensure the safety of the students, faculty, and administrators.”

Window Film Depot has the following tools and resources for Texas school systems:

  • Webinars reviewing product and grant information
  • Compliance guidance for school administrators
  • A user-friendly RFP template to expedite the estimating process
  • Onsite and online threat-level assessments
  • Professional installation services

Estimates from Window Film Depot are broken down by zone, Zone 1 encompassing doors and entryways, per the state standard requirements. Zone 2 covers perimeter windows, which can be added-on and itemized at the school’s discretion for maximum security. TIPS-USA contract pricing is available statewide. Window Film Depot is also a GSA Contract Holder.

School systems are to verify that the new requirements, including security film, are met with the 2023 school year, with a contractor and a timeline in place no later than August 2023.

Schedule a 30-minute webinar to learn how Window Film Depot can assist in meeting School Safety Standards rule requirements.

Can Bulletproof Glass Be Broken? Bulletproof Glass Myths and Misconceptions

Read More

Commonly used to secure building or car windows, bulletproof glass is designed not to shatter when an object, such as a bullet, hits the surface. It’s often installed as an added security measure in homes, commercial buildings, schools, and government institutions.

Although it is referred to as “bulletproof,” bulletproof glass isn’t designed to be completely impenetrable to bullets. depending on the thickness and quality of the glass, some types of bulletproof glass will shatter with continual impact. These are some of the key myths and misconceptions you should know about bulletproof glass.

6 Common Misconceptions About Bulletproof Glass

1. No Type of Glass Is Completely Bulletproof

Despite the name, there is no such thing as bulletproof glass. While often marketed and portrayed as such, it’s more accurate to call bulletproof glass, “bullet-resistant.” Bulletproof glass can’t deflect bullets or objects. Instead, most of these products absorb the impact of bullets. While bulletproof glass will dissipate a bullet’s energy and prevent damage, certain objects and high-speed bullets can still break through its surface. Some types of bulletproof glass will even deflect a bullet or object.

2. Bulletproof “Glass” Often Isn’t Made of Glass

Because a normal pane of glass is unable to bend and absorb kinetic energy, it will instantly shatter when impacted by a high-force object, such as a bullet or sledgehammer. Many types of bulletproof glass are made from a combination of durable glass and plastic layers, while some are completely made of acrylic or polycarbonate. These film stacks help to absorb the bullet’s impact and prevent the window from shattering.

3. Objects Can Break Through Bulletproof Glass

Despite action movies with bulletproof cars withstanding non-stop rounds of bullets, it is possible for objects to break through bulletproof glass. This depends on a few factors, such as how the glass is made, what it’s made of, and how thick it is. Some types of bulletproof glass are susceptible to repetitive gunshots, blunt objects, and explosions.

4. There’s More Than One Type of Bulletproof Glass

Many people fail to realize that there are multiple types of bulletproof glass solutions. Some variations are made from layers of glass and plastic, while others are completely made of plastic. Other solutions, such as window shields or films, are designed to be applied over existing windows. These different types of bulletproof glass vary in cost and effectiveness, with more expensive solutions tending to be the most resistant to violent forces.

5. It Has More Use Cases Than Just Cars

While the term “bulletproof glass” typically conjures images of bulletproof cars and SUVs, this type of glass is also widely installed in commercial and government buildings, homes, and schools. It provides an extra level of security to any property, protecting people inside the space by keeping intruders and objects outside of the building.

6. It’s Legal for Businesses and Homeowners to Install

Some might think that bulletproof glass is only available for use by politicians and celebrities, but everyone can benefit from utilizing it as a security measure. It is legal for building owners to install bulletproof glass anywhere on private property in order to resist forces from bullets and break-ins. Whether you’re looking for added protection for your car or in your home, bulletproof glass is a valuable option to defend your property.

So, How Does Bulletproof Glass Work?

Glass is a fixed surface that cannot bend to absorb an object’s impact, which causes it to shatter when impacted by a bullet or other hard item. Bulletproof glass works by combining layers of plastic and glass so the plastic can absorb the object’s momentum, preventing it from going through the glass. The thicker the bulletproof glass, the more likely it is to be effective in stopping an object from breaching the barrier.

If bulletproof glass is hit with multiple rounds of bullets, it will likely have marks and cracks. High-quality glass solutions are designed not to shatter or allow the bullets to go inside, despite what damage to the exterior may be visible. It is important to keep in mind that bulletproof glass can change how much light enters a building or create optical distortions. For public buildings such as schools, however, these slight drawbacks don’t outweigh the safety benefits of installing thick, bulletproof glass.


The Different Types of Bulletproof Glass

There are many different variations of bullet-resistant glass commonly used to protect against damage to buildings and vehicles. Each variety differs in durability, cost, materials, usage, and quality.

Laminated Glass

This type of shatterproof glass was the first on the market. Laminated glass is made of a combination of glass and PVB plastic or resin interlayers. While less susceptible to shattering than glass, laminated glass is not completely bullet-resistant. The lamination prevents the glass from shattering inward, but it may not stop a bullet from entering a building.

  • What is it made of? Laminated glass is made of glass and layers of PVB or resin.
  • Durability: While more durable than regular glass, it is unlikely to prevent a bullet or blunt object from puncturing through the glass.
  • Where is it used? Laminated glass is frequently used in vehicles, tall buildings, skylights, balconies, and frameless glass railings.
  • Pros: It’s more challenging to break than regular glass, therefore it is useful as a popular security choice for homes and retailers, as well as helping to protect windows against hurricanes and natural disasters.
  • Cons: Laminated windows are more expensive to repair than regular windows. They may not be able to protect against a determined intruder or a powerful explosion.


Acrylic glass is one of the most common types of bullet-resistant glass. This material is easy to cut and form into unique shapes, like curved windows. Acrylic is not noticeably different from glass, and is able to easily allow sunlight to pass through. Depending on the thickness, acrylic glass can protect buildings from bullets and blunt objects.

  • What is it made of? Acrylic glass is made from a single sheet of acrylic. For better protection, multiple pieces of acrylic can be laminated together.
  • Durability: Acrylic is usually resistant to impact and has 17 times the impact strength of glass.
  • Where is it used? It can be installed in homes, churches, and commercial buildings.
  • Pros: It’s 30 times stronger and twice as light as traditional glass. Acrylic glass is one of the more affordable options on the market.
  • Cons: Acrylic glass is more likely to scratch than glass and isn’t heat resistant. Also, it doesn’t offer the highest level of ballistic protection.


Polycarbonate is a synthetic material that is made up of thermoplastic polymers that contain carbonate structures within their chemical makeup. Polycarbonate is particularly strong and durable.

In addition to being strong and durable it is lightweight, it is softer when compared to other bullet resistant materials. Because of polycarbonate’s softness, it can actually “catch” a bullet within the sheet. The material will not shatter into dangerous shards. As a result, the bullet will not ricochet around the interior protected space potentially causing further damage or injury.

  • What is it made of? Polycarbonate windows and doors combine acrylic, PVB film and polycarbonate, made up of thermoplastic polymers containing carbonate structures in their chemical makeup. Sometimes, polycarbonate sheets are fixed to the outside of existing windows.
  • Durability: Durable against blunt objects and bullet-resistant.
  • Where is it used? Typically installed in commercial businesses and buildings.
  • Pros: It provides a sturdy layer of fragment resistance, is lightweight, easy to cut and shape, and simple to install.

Glass-Clad Polycarbonate

Delivering superior protection against forced entry attempts, glass-clad polycarbonate is made of polycarbonate, acrylics, and other plastic resins. This bullet-resistant glass is more difficult to break than laminated glass. Designed to withstand firearm threats and bomb blasts, it’s one of the most durable bulletproof solutions on the market.

  • What is it made of? Glass-clad polycarbonate is made of a combination of polycarbonate, plastic resins, and glass.
  • Durability: It’s highly unbreakable and impenetrable. Likely to withstand firearm threats, explosions, and aggressive attacks.
  • Where is it used? Installed in military or law enforcement vehicles, government buildings, courthouses, banks, schools, and stadiums.
  • Pros: It will protect glass from gunshots, explosions, and blunt objects. Typically wears well and is used for exterior windows and doors.
  • Cons: It’s one of the most expensive types of bulletproof glass. Glass-clad polycarbonate tends to have poor light transmission


glass thickness impacts bullet resistance

Glass Thickness Impacts Bullet-Resistance

While the material of bulletproof glass certainly impacts its durability and ability to resist impact, the thickness of the glass can change its level of protection. To standardize glass protection ratings, the Underwriter’s Laboratory (UL) created a 10-level scale. They’re a global safety science company dedicated to research and standards development.

Most bulletproof glass provides Level 1 through Level 4 protection on the UL’s scale.

    • UL 752 Level 1 – Stopped three bullets from a small-caliber, 9mm handgun.
    • UL 752 Level 2 – Stopped three bullets from a large-caliber, 357 handgun.
    • UL 752 Level 3 – Stopped three bullets from large guns such as .44 magnums.
    • UL 752 Level 4 – Stopped one bullet from a .30 caliber rifle.

See how the type and thickness of glass change its resistance to bullets.

Glass Laminate

  • 1.185 Inches – Level 1 Protection
  • 1.4 Inches – Level 2 Protection
  • 1.59 Inches – Level 3 Protection


  • 1.25 Inches – Level 1 Protection
  • 1.375 Inches – Level 2 Protection


  • 0.75 Inches – Level 1 Protection
  • 1.03 Inches – Level 2 Protection
  • 1.25 Inches – Level 3 Protection

Glass-Clad Polycarbonate 

  • 0.818 Inches – Level 1 Protection
  • 1.075 Inches – Level 2 Protection
  • 1.288 Inches – Level 3 Protection
  • 1.338 Inches – Level 4 Protection
  • 2.374 Inches – Level 8 Protection

Overall, glass-clad polycarbonate is the most bullet-resistant. Acrylic panels provide the least ballistic protection, while glass laminate and polycarbonate are ranked between Levels 1 and 3. However, notice that glass laminate must be much thicker than polycarbonate to maintain the same levels of protection.

What Can Break Bulletproof Glass?

As discussed above, the type and thickness of glass change how resistant it is to impact. But what objects can break bulletproof glass, and how quickly?

  • Guns: Repeated gunshots can eventually cause bulletproof glass to shatter and break. However, it depends on the type of gun and how many shots were fired. While glass-clad polycarbonate is the most durable type of glass against gunshots, shots from certain caliber handguns and rifles may eventually wear it down.
  • Sledgehammers: Sledgehammers can’t break polycarbonate or glass-clad polycarbonate, but they can shatter acrylic and laminated glass. However, it would take several minutes or even hours for someone to break it.
  • Dynamite or explosives: Many types of bulletproof glass are resistant to explosives. If an explosive is detonated one or more times near the glass, however, it will eventually shatter. It’s important to note that these types of explosives are illegal for civilians to own.

What Does Bulletproof Glass Protect Against, and Who Should Install It?

Bulletproof glass provides an added layer of security to buildings, including religious buildings and detention centers. It’s an excellent way to protect people during active threats, such as a shooting or break-in. By preventing shattering glass and flying bullets from entering, it can keep people safe and give them time to call for help. The following types of buildings and institutions benefit from bulletproof glass:

Schools and Colleges

With school gun violence on the rise in the United States, security officials and schools are looking for new ways to protect students. Bulletproof glass is part of the answer. Laminated glass and window films can prevent windows from shattering and potentially slow down the intruder, however polycarbonate is the best defense against active shooters. It’s engineered to prevent both bullets and the shooter from entering the building. Bulletproof glass can also be installed in interior rooms as a double layer of protection.

Commercial Buildings

From retailers to banks, businesses are at high risk of break-ins. Regular glass makes it much easier for intruders to quickly break into and enter buildings. Bulletproof or shatter-resistant glass can help burglar-proof a building and make it more challenging for criminals to enter. With so many varieties of security films and bulletproof glass on the market, choosing to install is an easy solution for a building owner to improve the security of first-story windows and doors.

Government Buildings

Government facilities, such as embassies, courthouses, and law enforcement, demand very strict security measures. Many of these buildings require bulletproof windows and doors to protect occupants from bullets and projectiles. Government vehicles, such as police cars, may also have bulletproof windows and windshields to protect against gunshots.


Nowadays, even homeowners are installing bulletproof and shatter-proof glass in their homes to protect against intruders and natural disasters. Bulletproof glass is resistant to high winds and debris caused by thunderstorms or hurricanes. From front and back doors to first-level windows and garage windows, there are many different places homeowners can have bulletproof glass and window film solutions installed.


In addition to government officials and law enforcement, many celebrities and high-profile individuals are hiring professionals to install bulletproof windows and windshields in their cars. While it’s more costly than regular glass, bullet-resistant glass can be life-saving if dangerous situations arise.

window film depot anniversary interview

After decades of commitment to the window film industry, Window Film Depot is excited to announce that it is turning 30! To celebrate this business milestone and Window Film Day, we sat down with Jeff Franson, FutureVu President, and Krissy Mosby, Window Film Depot President, to reflect on their journeys within the company, their entrepreneurship, and the window film industry over the years.

From Modest Beginnings: The Start of Window Film Depot

Raised by a family of successful entrepreneurs, Jeff Franson always thought he’d run his own business. Yet jump-starting a career in window film was never a part of the original agenda.

While at college, Jeff was studying on a pre-law track; after he learned what attorneys actually did every day at work, however, he quickly came to the conclusion that law was not a field he was excited to work in. From there, Jeff shifted gears.

Following in his family’s footsteps, Jeff determined that the life of an entrepreneur offered excitement, freedom, and innovation. While some would have shied away from the risk of building a new business from the ground up, Jeff embraced the opportunity to capitalize on product gaps in the market. Once he decided that he wanted to build an impactful and successful brand, he drew from previous experiences while exploring potential business ideas.

“I was always comfortable working on homes and buildings,” Jeff explains. “An opportunity presented itself in Atlanta, and I took it. I started to work with my brother on a home services business.”

Jeff Franson and Window Film Depot's Modest Beginnings

Eventually, Jeff and his brother discovered an opening in the market for window film.

“Ultimately, we ran across a really cool product: window film;…people loved it, and they didn’t know where to buy it. So, we kinda ran across it by mistake, and recognized it as a nice long-term business opportunity that we pursued.” With this, the first evolution of Window Film Depot was born.

Initial Growth and Expansion

Window Film Depot found immediate success. Jeff’s hunch that there was a market for window film was proven to be correct, and he discovered his opening at the perfect time.

“We went into Atlanta, which was an extremely strong market for what we do,” Jeff describes, “especially in the 90s and early 2000s, the home market being as explosive as it was. Every day we’d have successes in the field…we’d go out to neighborhoods, knock on doors, and get business.”

As sales rose, so did the need to hire a larger team. Jeff marks Window Film Depot’s early ability to recruit talented and driven individuals as one of the brand’s first major wins, serving as an indication that the company was on the right track.

One such talented hire? Krissy Mosby, who joined Window Film Depot as an intern in 2005. Similar to Jeff, Krissy wasn’t originally on a path to window film; she thought she would work in medicine, and had been completing her prerequisites for medical school before taking an opportunity with WFD.

“I started working answering phones, stuffing envelopes, doing mailers, stuff like that,” says Krissy. As she continued through school, her responsibilities increased. “(By the time) I graduated, I was doing sales, and even managing one of the small accounts we had. Jeff offered me a full-time position right out of college. Starting to work instead of going right back into school sounded a lot better at the time!”

Thus began a period of foundational growth for the company; with valued team members and an established local market, it was time to expand even further.

Adapting to a Changing Market

Boosted by a young, determined team and modern capabilities, Window Film Depot rapidly transformed with the times, leveraging new innovations in technology to outpace its competitors.

“We were young in an older man’s business, quite frankly,” explains Jeff. “The internet, early on, was the biggest accelerator of our growth. We employed tools more rapidly than our counterparts…we got out front very quickly, with local landing pages in 40-50 markets around the country.”

Ebbs and flows in markets also drastically changed Window Film Depot’s business model, inadvertently breeding expansion. While largely a local company up until 2007, the housing crash forced Window Film Depot to shift from residential to commercial business. Krissy experienced this shift firsthand.

“Back when I joined, our company was very local here in Atlanta…we were over 95% residential. We started to see a need for a national presence; people had multiple locations, and wanted us to take care of all of them.”

“Around 2008, is really when our business changed. Fast forward, and now we’re over 90% commercial. We’re one of the largest 3M dealers in the country, servicing national accounts.”

This tremendous growth led Window Film Depot to be recognized as the #1 3M Window Film Dealer in the US for multiple years. Even Jeff didn’t foresee this type of growth; according to him, he expected that their team was capable of achieving it, but gaining the title was never a goal. Instead, earning that recognition was a byproduct of Window Film Depot’s commitment to their customers.

It was also around this time that Krissy gained a more major role within Window Film Depot, planting the seeds for the company’s leadership in the future.

“Jeff, who was the President at the time, stayed behind after work one day and asked me if I wanted to become one of the owners of Window Film Depot,” Krissy recalls. “It showed I was valued, and that he wanted me to be a part of the company permanently.”

Impact Security, FutureVu, and the Future of Window Film Depot

As business continued to expand, Window Film Depot began to run into client needs they couldn’t yet handle. With a team full of entrepreneurs, Window Film Depot saw these needs as opportunities to innovate, resulting in the creation of Window Film Depot’s sister brands.

Take, for example, Impact Security, LLC. Window Film Depot customers began experiencing severe smash & grab attacks on their stores; traditional window film wasn’t cutting it. After combing for solutions, Jeff recognized another gap in the market.

“We didn’t see what we thought we needed, partnered with engineers, and invented retrofit security shields,” he explains. From there, Impact Security branched off and became a separate entity from Window Film Depot.

After founding several more successful brands, Jeff created FutureVu to be a single, holistic parent company. While brands such as Window Film Depot would still operate on their own, FutureVu would oversee all company operations, searching for other brands to add to the family.

Today, the FutureVu umbrella encapsulates a number of diverse brands, including Window Film Depot, Impact Security, CoolVu, and LongVu Wholesale Company. Although Window Film Depot was once a group of up-and-comers, Jeff explains, they are now industry leaders, a successful model that others seek to replicate.

“8-10 years ago we went from the young guns who were pushing too hard in a lot of people’s minds, to ‘Wow, these guys have done something special and they’re willing to share.’ No longer am I a young gun, but I’m right in the middle as a forty-something-year-old…I’m considered one of the older guys!”

Window Film Depot: A Pioneer of Female Leadership in Window Film

While Jeff leads FutureVu, Krissy has taken the helm as president of Window Film Depot.

She’s grateful for concentrated internal efforts to support her growth as a professional, especially in such a male-dominated industry.

“(Window Film Depot) never limited any opportunity that came my way, or any opportunity within the company…I was never told no,” explains Krissy. “I was always brought new opportunities based on what I had achieved…they would never leave me out because I was a woman, or new, or anything like that.”

From the company’s start, Window Film Depot has relied on contributions from dedicated women. During early pushes for sales, Jeff’s wife, Hanna, was instrumental in getting the ball rolling.

“My wife, we’ve been together for over 25 years…she and her girlfriends would rollerblade around neighborhoods with flyers,” recalls Jeff. “It wasn’t just me out there, it was a team.”

Even with such a supportive work environment, breaking into the construction industry (or any male-dominated field) isn’t easy for female professionals. Krissy gave specific advice for women looking to succeed like she has.

“Don’t let yourself be intimidated by being the only woman in the room. If at first, it seems like you’re getting pushed back for being a woman, stand strong in your opinions. Be knowledgeable, and you’ll gain the respect of anyone in a conversation.”

Today, Krissy hopes to lead the charge on growing Window Film Depot even further and maintain the positive work culture that kept her on board for so long in the first place.

“There’s always room for growth and improvement in every aspect of the business…continuing to maintain our company values, and striving to make the office a fun and safe work environment. I’ve been with the business for over 15 years…so many of our employees are 5+, 8+ employees of WFD.”

Closing Advice From Jeff to Young Entrepreneurs

To bring things to a close, we asked Jeff to offer words of wisdom to other young entrepreneurs looking to run a business of their own as successful as Window Film Depot. According to Jeff, it’s essential not to fret the small stuff.

“Control the things you can control, and don’t let the things you can’t control worry you or bother you, even though it might be expensive…things are going to happen that are out of your control, and if you sweat every detail you’ll have a heart attack. Focus on blocking and tackling, and you should be able to survive.”

As the past 30 years has proven, Jeff has taken his own advice in stride, exemplifying outstanding leadership with strong leaders such as Jeff and Krissy at the helm, working in tandem to support innovation and drive success in the company. We look forward to another 30 prosperous years of Window Film Depot!

Benefits & Best Practices for Using Window Film for Historic Window Restoration

window film historic window restoration

Are you looking for a better alternative to new glass additions for a government-owned historic building? Historic window restoration is another suitable option for revamps.

Older buildings provide a sense of nostalgia that allows us to recollect memories from our past. This especially applies to long-standing governmental properties found in historic neighborhoods and major cities. Many have a gorgeous architectural style with classic features and design accents, including vintage-style window film frames. The most popular styles back then were stained glass, arches, and transoms.

Upkeep of a historic property may present greater challenges than that of a modern design. Building decomposition and outdated framing styles are just two of many threats faced by historic building owners. On top of that, they’re up against present-day building code requirements that can be costly to adapt to meet.

When structural window damage affects a government-owned property, remodels should quickly follow. Some building owners automatically believe that new window installations are the answer. To replace window film entirely is not only costly. It can also compromise a building’s historic integrity. Ideal upgrades to an older property should preserve the property’s original elements as closely as possible.

3 Benefits of Historic Window Restoration

When restoring windows on government-owned historic buildings, the U.S. Department of Interior recommends the usage of window film. They even provide guidelines and best practices for doing so in their “Standards for Rehabilitation & Illustrated Guidelines on Sustainability for Rehabilitating Historic Buildings.”

When the time comes for window renovations on an older property, these benefits alone should convince you that window film restoration is the way to go.

Preserves & Restores Historical Buildings

Simply put, you’re more likely to keep a historic building’s appearance intact with window film restoration–not window film replacements. Going the route of preservation and restoration has its fair share of benefits, including the avoidance of glass damage and the protection of valuable interior furnishings.

Proper maintenance on a building’s original windows is not as invasive as other methods of repair. It’s also less expensive, less time-consuming, and much more sustainably sound.

Increased or Improved Energy Efficiency

Professionally-restored windows are known to increase energy efficiency, which can potentially lead to a 25-30% reduction in heat escaping from the windows.

Much can also be accomplished by retrofitting historic windows with clear film or high-performance glazing, including greater energy efficiency that’ll likely reduce cooling costs by 25-30%.

Additionally, retrofitting curtain-wall systems and historic steel windows has its fair share of sustainability perks–one being improved thermal performance and greater indoor comfort

Advanced UV Ray Protection

When restored properly, window film achieves the goal of blocking harmful UV rays. This can increase prevention of skin damage and deterioration of property valuables.

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.
