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.

Glare Reduction (%)

This is the ability of the window film to reduce glare from the sun and other sources of light.

Window films benefits can help reduce eye strain & improve our lives by reflecting away negative sun’s heat.

The higher the %, it means it can shield away more sun’s glare entering into our spaces.

Shading Coefficient

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.

Top 5 Window Film Terms

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 percentage (%)light passes through different materials, including glass used for windows and doors.

Ultra-Violet Rejection (UVR)

The ultra-violet rejection refers to the amount of ultraviolet light that doesn't make its way through windows. 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.

Total Solar Energy Rejection (TSER)

Total solar energy rejection refers to the amount of solar energy that is prevented from entering a space or a building, usually through the use of specialized materials or technologies.

This term is commonly used in the context of building design and construction, where the goal is to minimize the amount of solar heat gain that occurs within a building’s interior.

Solar energy rejection is typically expressed as a percentage of the total solar radiation that is incident on a surface.

For example, a window with a solar energy rejection rate of 70% will prevent 70% of the incoming solar radiation from entering the building, while allowing the remaining 30% to pass through.

The ability to reject solar energy is an important consideration in building design, particularly in warm or hot climates where excessive solar heat gain can lead to uncomfortable indoor temperatures, increased cooling costs, and decreased energy efficiency.

Care & Cleaning Tips
Maintainence Of Window Films

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. 

It is important to know how to clean your windows now that you have an extra layer added to them.

  • 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.
