Frequent Questions

V-KOOL® - Heat insulating film for automotive glass

1. Why is film V-KOOL so expensive?

V-KOOL's patented revolutionary technology was voted one of the 100 greatest inventions of the millennium by scientific journals enjoying the 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 ultraviolet 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 It is a product that beat other ¥ films using outdated technology and using cheaper methods.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.

2. What is the difference between V-KOOL and XYZ (heat absorbing film competition)?

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 spectral filter 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.

3. How long has V-KOOL been on the market? Are there any trial and trial data available?

V-KOOL was first installed in 1991 in the United States. Performance data were collected using the Perkin-Elmer Lambda 9 Spectrophotometer combined with the Windows and Daylighting Group's "Window 4.0 Fenestration Program" at Lawrence Berkeley Laboratories, a scientific group. Study on the first film in the world. It has been certified in many countries such as Singapore, USA, Thailand, Malaysia, etc.

4. Does V-KOOL meet traffic regulations?

For safety reasons, the Road Administration of some countries in the world requires all car owners to meet the following requirements when pasting film:
a) Not to be reflective.
b) Transmission of the front glass and the two front doors shall be at least 70%.
c) The light transmission for the rear glass and the two rear doors shall be at least 25%.
d) 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.

5. I can paste filmV-KOOL cheaper at another store. Why are you selling it more expensive here?

V-KOOL prices are standardized and fixed. The price is the same whether ordered or executed by any authorized dealer of V-KOOL. If someone offers V-KOOL cheaper, we are afraid V-KOOL film. For sure, you can confirm with our office by phone: (84-4) 38 314 357. Or Hotline: (84-4) 983 240900 - (84-4) 902 187881.

6. Can V-KOOL be scratched easily?

V-KOOL has a hard and scratch-resistant coating under normal maintenance conditions. The scratch-resistant, scratch-resistant, 100-wiped abrasive abrasive abrasives used in taber grinders with a pressure of 500 gm / square inch of smooth steel. However, similar to the glass surface, if you use a sharp object to impact the surface will cause scratches. V-KOOL is the same.

7. How to paste V-KOOL?

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. You can refer to how to paste the film from the 'The Making of V-KOOL' manual. In 'The V-KOOL Experience', there is a video presentation.

8. How long is the warranty period?

V-KOOL in Vietnam has a 10-year warranty on the phenomenon of peeling, cracking, flying colors and the original errors of the film.

9. How long does it take to film?

Depending on the size and model of the car. A sedan takes about 1 hour to 1.5 hours. A curved windscreen model (eg, Volkswagon, BMW) can take up to 2 hours. An MPV can take 2 to 3 hours.
Calls can be made to book ahead to avoid waiting on crowded days.

10. If there are bubbles or peeling in the film?

We call it 'good time'. 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.

11. Can V-KOOL be applied on polycarbonate resin? (Note: some polycarbonate sports cars)

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. Clients want to put the film on polycarbonate plastic will be at risk.
