Automotive window films can block over 99 percent of UVA and UVB rays, protecting you, as well as the interior of your vehicle. Glare Control Window films also reduce glare by as much as 80 percent, creating a much safer driving environment in strong sun, snow or rear headlight glare. According to Lisa Killen, automotive marketing manager at CPFilms, manufacturer of GILA products, window film can also perform a valuable safety function. Since 1978, American car makers have not been required to install laminated safety glass to the side and back windows of cars. As a result, these tempered windows can sometimes shatter from impact during an accident, exploding tiny glass shards around the passenger compartment.
Window film can provide some anti-lacerative protection by helping to hold shattered glass together.
The result, she concludes, is greater safety. Seat belts, warn the National Highway Safety and Traffic Administration, can deteriorate due to sun exposure. Many people associate window film with dark or faded purple tints that can be seen on some older vehicles. Actually, it's the lighter, higher performing films that provide the most protection and look the best on a car. The lower the percentage, the darker the film and the more privacy it offers.
