Frequently Asked Questions
V-KOOL was first introduced in the US in 1991. Based on research originally related to US aerospace and military use, V-KOOL is the world’s first wavelength selective window coating that provides a virtually transparent protective barrier against the sun’s heat and radiation. Wavelength selective coatings enable the Stealth Bomber to evade detection by reducing the aircraft’s radar footprint.
V-KOOL – Wavelength Selective Coatings
V-KOOL utilizes a proprietary and patented di-electric sputtering process that embeds super clear?substrate with up to 10 atomic layers of Indium Oxide and Silver that is further fortified with Gold.?This complex process gives V-KOOL its amazing heat reflection qualities without looking reflective? or dark. V-KOOL’s spectrally selective technology is based on the heat reflection technique.
Other Window Films in the Market
Other window films are mostly made out of common metals like aluminum, nickel and bronze.?These metals have some heat performance but come with compromised reflective look and do not ?allow as much daylight to pass through, making night time driving more difficult and dangerous.?Common metals also have the disadvantage of demetallization and the metals are deposited on?the film more unevenly. Common metals and its manufacturing technology are also significantly? cheaper in material cost. A discerning consumer will be wary of unethical retailers hawking these?films for more than their worth.
Films can be made of non-metals like oxides and nitrates. The benefits of these films are that they?do not have mirror-like surfaces. But their performance in heat rejection is usually compromised.?They work like “sponges”, soaking up heat instead of reflecting heat, so by nature; they are?classified as heat absorbing. Very cheap non-metals such as dyed films will even have color?fading under exposure of sun. Better performing non-metals like nitrates have some heat rejection?properties but they are typically darker, more absorptive and the surface of the film may be prone?to thermal cracks and lines. As the material cost is low, you may want to weigh performance and? benefit to overall cost.
No other film can transmit as much light and reject the same amount of heat as V-KOOL. VK 70 has the highest luminous efficacy in the industry.
Tentu saja, V-KOOL tidak lebih reflektif dari pada kaca polos (tanpa kaca film), jadi tidak akan mendistorsi atau lebih apakah anda siang atau malam hari.
V-KOOL is no more reflective than clear glass, and some of our films (as tested) have lower reflectivity than glass, so you keep your visual clarity day and night. VK-70 is 2% less reflective than glass that no other heat rejecting film can boast.
V-KOOL offers outstanding clarity with its premium films. In most cases in can actually improve the visual aspects of the window. No other film can transmit as much light and reject the same amount of heat as V-KOOL.
No, V-KOOL will have no effect on these devices.
V-KOOL does not necessarily make the glass stronger, but it will keep the glass intact if it is struck by a foreign object. We offer a safety film that takes a tremendous amount of abuse for safety and security applications.
V-Kool and other window films do make your glass shatter resistant. V-KOOL does have safety and security film for various applications. It will keep shards of glass from flying.
V-KOOL blocks 99% of the ultraviolet rays.
We do have glare reducing films but we do not eliminate the glare in its entirety. To do this you would need to block the majority of the natural light.
There are other factors that cause fading; such as heat, light, and the quality of the materials you are trying to protect. V-KOOL does reject 99% of the ultraviolet rays which is the main component of fading, no window film or any other glass product stops fading completely but V-KOOL will substantially extend the life of your furnishings.
V-KOOL has a full line of products that solve almost all energy related problems. Let us explain the difference in each of our products, which will in turn explain cost and technology. Click here to go to our product page.
No, ceramic products are based on the technology of absorbing heat. Due to the high absorption rates, ceramic films cannot offer comparable solar heat gain coefficient measurements with equal light transmission as V-KOOL. V-KOOL is a metalized product that contains microscopic gold and silver particles that rejects the heat without a shiny appearance versus absorbing heat.
You will have more visible light transmission and better solar heat rejection while creating less stress on the glass from absorption.
Yes, V-KOOL can be custom fit to most any size of glass, realizing that the installation time may be the same on a small piece of glass as it is on a large piece of glass.
Because V-KOOL is reducing heat gain, your HVAC system should be used less. Less running hours should result in less maintenance expense and prolong the life of your system
V-KOOL will reduce the amount of heat let in through your windows, and this will reduce the amount of run time for your air conditioning unit. This will cut down on utility bills and enable your air conditioning unit to have a longer lasting life.
We only use trained professionals to install our film so that you do receive 5 years warranty.
V-KOOL is applied on the inside of the glass and our certified installers use the proper tools and equipment to guarantee your application. Water is used to activate the adhesive, so it may take up to 30 days to completely dry.
V-KOOL is warranted to never bubble or change colors. V-KOOL is made of silver and gold and does not use dyes, which have a tendency to change colors because they are not stable. Bubbling is usually a result improper installation, so no window film should result in bubbling.
Do not wash windows until (30) days after installation of V-KOOL. When cleaning use a soft towel or cloth or a clean synthetic sponge. Use common cleaning solutions such as warm water and detergent. Do not use solutions that contain abrasive materials.
V-KOOL has a scratch resistant coating and has passed the ASTM D-1044 Scratch Resistant Test.
V-KOOL has a hard and scratch-resistant coating under normal maintenance conditions. However, similar to the glass surface, if you use a sharp object to impact the surface will cause scratches. V-KOOL is the same.
For safety reasons, the Road Administration of some countries in the world requires all car owners to meet the following requirements when pasting film:
- Not to be reflective.
- Transmission of the front glass and the two front doors shall be at least 70%.
- The light transmission for the rear glass and the two rear doors shall be at least 25%.
- The front windscreen shall not obstruct, interfere with or interfere with the transmission of signals between the In-vehicle Unit and the Electronic Road Pricing System.
FilmV-KOOL is the only film in the world that allows 73% light transmission and 94% IR reduction. Transparency meets the legal requirements of traffic safety in the world.
V-KOOL's patented revolutionary technology was voted one of the 100 greatest inventions of the millennium by Popular Science Magazine United States. V-KOOL uses 1% ultra-high quality transparent polyester and is sprayed on expensive metal atoms, such as silver and indium oxide. The film is manufactured by a multi-layer Magnetron Coating System that costs up to $ 24 million. Therefore, film products have high efficiency in terms of light transmission and infra red ray removal. It is a product that beat other ¥ films using outdated technology and using cheaper methods.
In fact, with the superior performance of V-KOOL and the ability to save costs in the long run, one can assume that the price of V-KOOL is matched with the higher efficiency than the product has high price.
V-KOOL exclusively utilizes a patented, patented, electroplated spraying process in super-transparent matrix technology coated with 10 layers of indium oxide, silver and reinforced with gold. This state-of-the-art technology makes V-KOOL extremely resistant to heat without glare or hindrance. V-KOOL's spectrally selective technology is based on heat reflecting technology.
The heat absorbing film absorbs infrared light, which accumulates heat as heat is radiated back. Heat-absorbing films generally use heat-absorbing chemicals that are added to a dye or additive, which may fade or become loose, thus less durable. These films are cheap because of the cheap materials and the process of adding dye to polyester is a poor technology, unlike the multi-layered ones used in V-KOOL products. After the film's thermal capacity reaches the limit, all the heat is absorbed into the vehicle. Heat stress on the glass can break or crack the glass.
V-KOOL is glued to the inside of your vehicle's glass. Before proceeding, the inside of the glass is cleaned with a mild solution such as Johnson Baby - a baby shower gel with pure water. Film has a layer of pressure glue, which helps the film stick to the glass. The process of installation is manual process which takes time and must be skilled, not made of machinery. Therefore, for curved glass vehicles, it takes more time and skill.
Depending on the size and model of the car. A sedan takes about 1.5 hour to 2 hours. A curved windscreen model (eg, Volkswagon, BMW) can take up to 5 hours. An MPV can take 3 to 4 hours.
Calls can be made to book ahead to avoid waiting on crowded days.
Film need not be repaired. Like after painting walls, the paint needs time to dry. Films with more layers will be more complex, so that the process will take longer.
In the first to two weeks, you can see a very thin film between the film and the glass. This phenomenon sometimes looks like a water bubble. Its density depends on weather conditions. On a sunny day and you parked in the sun, the speed of evaporation will be very fast. On the contrary on rainy days or if you parked at shade the speed of evaporation will be slow. A few weeks later, the film began to heal and the bubbles gradually reduced. It takes about 4-10 weeks for the film to dry completely.
For peeling, the film will not peel off after gluing unless the film edge is up or the window is pulled up or down for the first 48 hours after gluing. The V-KOOL adhesive attaches securely to the glass and increases durability over time, helping to prevent layering unlike cheap dye films that do not stand the test of time.
The polycarbonate sheet absorbs and then releases (transmits) more moisture than the glass. Since most high-performance films are metallized, these films create a barrier to moisture transmission. This activity causes bubbles or fringes under the film. The water vapor exits creates a pressure on the surface, the plastic and film. Another drawback is that most plastic sheets have scratch-resistant coatings. The coating makes the glue unstable. In fact, these coatings are designed with a smooth surface (low coefficient of friction) to minimize wear and scratches.
The main obstacle to plastic and solar films is the removal of the film. Nine out of ten times, the adhesive will pass to the plastic. When this happens, it is very difficult to remove the adhesive and ultimately not to scratch the plastic. We do not recommend sticking film on polycarbonate resins. Our warranty states that the film must be glued to the glass for full warranty under the regime.
We have many repeat customers and references that will attest to its quality. V-KOOL is independently tested and you will immediately feel the difference in our heat demonstration.
