The Advantages of Window Films

These films are an excellent solution if you're tired of dealing with lots of sunlight shining through the glass, making your property feel hotter than it needs to.

While they can prevent excess sunlight from making its way through, the films work just as well to block out UV radiation and prevent glare.

If you have them installed, you can enjoy a greater sense of privacy, increased comfort, and lower energy bills with cost savings that will continue benefiting you for years to come.

How to Achieve Window Energy Efficiency with Zenith Window Films

Zenith Window Films offers a wide variety of film options, including solar options providing the most energy efficiency possible.

For example, our clear series solar films have a visible light transmittance of 65%, offering a glare reduction of 23% and an ultraviolet reduction of 99%.

As a result, the inside of your property would remain cooler as the film prevents more of the sun from shining through your windows.

It’s just one of several types of films offering the energy efficiency you want and need to save much more money in the long run while keeping your property cool and comfortable.

If you want to achieve maximum energy efficiency through your windows, installing films is the most suitable decision. These films will reject the harmful UV rays from the sun, but they’ll also offer more shade and protection from the sun as it hovers over your property.

Angular Optical Properties

Angular optical properties are something to consider when working with windows. A set algorithm offers in-depth details on how the specific angle of a property impacts the overall level of light transmittance and reflectance in conjunction with different factors, including the glazing layers of the windows and the thickness of the glass used.

For example, how much solar radiation your windows absorb would depend heavily on the amount of light transmittance and reflectance, leading to more or less solar radiation, depending on different factors.

These types of calculations come in handy for several reasons. The measures can help you determine the kind of film needed to block out some of the daylight that makes its way into the building, causing the temperature to rise and creating an irritating, unwanted glare.

Shading Coefficient (SC)

The shading coefficient is a particular type of measurement used to determine the thermal performance of windows based on how much sunlight shines through them. It also indicates the level of solar heat transmitted through those windows or any other type of glass.

It’s typically best to see a lower measurement because there isn’t nearly as much solar heat transmitted through the glass compared to those with higher measurements.

The Top 5 Window Film Terms You Need to Know

If you’re thinking about getting window films installed, there are a few components you need to know of to help you understand the quality and efficiency behind the different options available to you.¬†Understanding these terms can help you decide on the perfect window films to invest in for your property, whether it’s your home, rental, or even the office building.

Visible Light Transmittance (VLT)

The visible light transmittance is another specific measurement that indicates how much light passes through different materials, including glass used for windows and doors. For example, glass windows with no tint would have a higher percentage of visible light transmittance than those with tinted films installed.

Ultra-Violet Rejection (UVR)

The ultra-violet rejection refers to the amount of ultraviolet light that doesn't make its way through windows. The window films act as a barrier to block out this ultraviolet light, reducing exposure to it while helping people maintain better temperatures in their homes and workplaces. High-quality window films work well enough to reject a staggering 99% of UV radiation, which is a good thing!

Visible Light Reflectance (VLR)

The visible light reflectance involves the beam of light that passes through your windows. Windows with films and glazing tend to transmit much less light by blocking it.

Solar Heat Gain Coefficient (SHGC)

On the other hand, the solar heat gain coefficient refers to the portion of solar radiation that pours through different types of glass, such as windows and doors composed of the material. When pouring through glass, the solar radiation quickly transmits heat and releases it throughout the property, which will cause the interior temperature to rise. Therefore, having a low SHGC reading is ideal because that would mean there isn’t as much solar heat inside the property, thus resulting in more shade and lower temperatures.

Care & Cleaning Tips: How to Keep Your Window Film in Excellent Condition

Once you’ve had your window films installed, knowing how to take proper care of the films to keep them in the best condition is a must. When we install window films, we take a careful approach while gently placing the material on the glass using soap, water, and a handful of other simple materials to get the job done. Because we take our time, have the installation experience, and use high-quality materials, you can expect these films to last long while offering the added UV protection you want and need. However, it helps to know how to clean your windows now that you have an extra layer added to them.

  • Don’t use harsh, abrasive cleaners. You don’t need anything too strong that could potentially damage your window films.
  • Only use soft materials when wiping down windows. For example, a microfiber cloth is the best product to use to prevent scratches when wiping away dirt and dust.
  • Keep it simple with the cleaning solution. You can get the job of cleaning your windows done without damaging the films by combining warm water with a bit of your favorite dish soap, mixing it, and then dipping your microfiber cloth in it before wiping the glass from top to bottom!


By following these simple cleaning tips, your windows and the films installed on them will continue to look amazing for years.
