V-KOOL® in engineering high performance solar control films, gives the brand a unique perspective in addressing issues and challenges related to aesthetics, energy-cost reduction, cost-efficiency, practicality, protection and safety.

To avoid the unfortunate consequences of excessive solar heat gain, window film manufacturers have been working to develop modern products which block more heat than light, doing it by reflection of the unwanted infrared radiation contained in the solar rays,while still admitting adequate amounts of visible light, necessary to see the outside, and to provide good daylight illumination of the interior.


Enjoy the ultimate protection from scorching infra-red heat and destructive UV rays without losing the sunlight or spoiling your home’s architectural integrity.


Hüper Optik Films Glair Control Ceramic 40 was chosen to control the ambient light.


V-Kool VK70 Performance



VK-70 (iQUE 73FG) film, originally developed for the US space and military program and now adapted for commercial use, features a 94% rejection of infra-red and a 99% rejection of ultra-violet spectrum while allowing 70% of visible light transmission. This makes it ideal for areas that require a high amount of clarity while preventing the least amount of heat to penetrate the interior.

Among the many commercial applications of VK-70 are retail outlets, penthouses, atria and air control towers, essentially places where optimal heat rejection and maximum clarity is required.



V-Kool VK55 Performance



VK-55 (iQUE™ 53GII) represents the next generation film to offer unparalleled solar heat and glare control in today’s market. Developed as the world’s first 10-sputter layer film by the late renowned scientist, Dr. Gene Woodward from Silicon Valley, 53GII is a product of over 10 years of extensive R&D and the first- of-its-kind in the world.

With glare control feature, the VK-55 has the ability to reject over 96% of infra-red rays, while still allowing as much as 58% of daylight to pass through, thus resulting in a solar heat gain coefficient of 0.41. Another unique feature is its visible light reflectivity of 7%, the lowest ever achieved with window films. This gives it the aesthetic quality of natural glass transparency that most architects prefer.


V-Kool VK40 Performance



VK-40 (iQUE™ 43FG) film is the premium choice for home or commercial owners who require less visibility and maximum solar control for their window films. With and amazingly high infra-red rejection of 98%, VK-40 minimizes the solar heat gain and glare problems from large window areas through its maximum solar heat control capability.



In order to get the right kind of window film for your window, look for the Visible Transmittance(VT) value for the film when applied to a single pane of clear glass. Then find the Solar Heat Gain Coefficient (SHGC) for the combination. If the VT value is greater than the SHGC value,you have the right kind of film for a hot climate window, but be sure to check the window manufacturer’s warranty before applying the film.The Light-to-Solar-Gain (LSG) ratio is the VT value divided by the SHGC value. The higher this ratio, the more spectrally selective the film and the better it is for hot climates. It is difficult, however, to achieve LSG values greater than about 1.2 with window films.

Soft multi layer coatings inside double pane windows, however, can achieve values as great as 1.6, providing good transmission of visible light (no dark appearance) as well as good solar heat gain rejection. In order to achieve good solar heat rejection with either a window coating or an applied window film, the SHGC value needs to be low (below approximately 0.3 to 0.5) to be effective—the lower the better. With an LSG ratio of only 1.1, for example, this means that the visible transmittance (VT) value will be about0.33 to 0.55. Low values in this range can impart a dark appearance to the glass and may be objectionable. For sun rooms with vast expanses of glass exposed to the direct sun for much of the day, however, values as low as 0.3 to 0.4 for the VT should not be objectionable, especially since these values can produce SHGC values below 0.3 to 0.4 with window films having LSG values greater than 1.0




V-Kool® goes to great lengths to verify the accuracy of their performance data. When you have the best performing film in its class, it is important to verify product performance by using a neutral third-party organization that is respected by the Federal Government, the glass industry, and noteworthy organizations such as Lawrence Berkeley Laboratories. The "National Fenestration Ratings Council" (NFRC) is the same organization that rates the performance of windows, skylights, and doors so that consumers can have a reliable and accurate way to compare one product to the next. V-Kool® Films are NFRC Certified for your piece of mind, you can rest assured that the performance data published by V-Kool® is accurate and reliable. 



Tips & Facts

Mastering V-Kool Film Technology

Conquering the heat while maintaining an eco-friendly “green” home or workplace might seem an impossible reality given today’s changing climate. Too often, you spend a lot on energy costs just to maintain a cool temperature inside your house while unknowingly increasing your carbon-emission footprint on the environment.

Films engineered with V-KOOL® technology, now allows you to achieve a cooler home while generating savings with ease. With its solar and glare control technology, V-KOOL® gives you an advantage of intelligently taking control of the heat entering your space. With less indoor heat, this means less energy spent making it cooler and more savings for you.

Please read up on our facts, learn our tips and achieve that environmentally friendly place that you can truly be proud of.


Fact #1: Infra-Red Radiation is Heat Radiation

  • The infra-red radiation that comes from the sun is the one wavelength that increases the heat level of any object that it strikes.
  • Glass windows permit the infra-red to enter a space, making it heat up faster.
  • Air-conditioning rooms with large, clear windows end up costing more energy since it is constantly bombarded and heated up by infrared rays.

Tip #1: With V-Kool, IR means “instantly reject.”

Applying V-KOOL® films on your window glass is the best way to reject infra-red rays and lower the heat. With its patented technology, V-KOOL® films offer an unparalleled level of infra-red reflectivity, as high as 98%, to instantly reject these solar rays from penetrating into a given space. The result – less heat buildup in the area protected by V-KOOL® films.


Fact #2: Ultra-violet rays burn

  • Ultra-violet radiation is invisible to the eye and one of the most harmful of the sun’s rays.
  • Sunburn and heat are some of the most common effects of ultra-violet rays.
  • Ultra-violet rays can penetrate your home through glass windows.

Tip #2: Sunscreen lotion for your skin, V-KOOL® films for your windows

V-KOOL® films works just like sunscreen on your skin, protecting you constantly from the damage caused by ultra-violet rays. With as high as 99% ultra-violet rejection, V-KOOL® films prevent the UV rays from penetrating your homes or office through the glass. Heat level and build up is greatly reduced within the V-KOOL® protected space. So come Summer time, or even throughout the year, it is best to be protected from UV with V-KOOL®.


Fact #3: Don’t play the losing game with solar heat gain

  • Solar heat gain refers to the increase in temperature in a space, object or structure because of solar radiation.
  • Objects absorb sunlight and convert the energy into heat.
  • Re-radiated heat from objects increases temperature in the surrounding space – also known as the greenhouse effect.
  • Even with air-conditioning, objects will continue to absorb sunlight and radiate heat, making it more difficult to cool down a room.

Tip #3: Less is more with V-KOOL®

Less solar heat gain means more energy savings with V-KOOL® films. With a solar heat gain and shading coefficients of less than one in most variants, V-KOOL® films drastically lessens and controls the amount of heat buildup in objects in a room while still letting in visible light. As a result, one can easily cool down a space using less energy through minimal air-conditioning.
