Window tint is a very popular accessory for cars, especially in areas where the temperatures can be hot and oppressive. While some people have window tint applied for cosmetic reasons the main reason for having it is to protect the interior from sun damage and to keep the inside of the vehicle cooler. Window tint film is made of polyester with a thin layer of substances that create the shade of the tint.
These substances consist of various dyes and metals as well in some cases. The window film is bonded to the glass with very powerful glues, much better than when tint first came out years ago. One of the biggest myths in the window tint industry is that having dark tinted windows will impede your ability to drive at night. While this is certainly a possibility if one disobeyed the law and placed dark limo tint on every window, it is not true if the tint is applied properly.
In most states in the U.S. you can only have the darkest window tint on the rear windows. The window tint is applied to reduce glare and will not interfere with your night driving ability.
Another big myth is the thought that the window tint is placed on the outside. If you think about it, this wouldn't even be practical. With objects hitting your windows all the time the film would quickly become damaged and be useless. Normal windows that don't have tint applied to them only reflect about 5% of the visible light while transmitting 90% into the vehicle. Another 5% is absorbed by the glass.
In contrast when tint is applied to your automobile's windows as much as the visible light transmitted can be as low as 15% and the light reflected may be as high as 30% or more. Just by looking at these numbers it is easy to see how window tint works to keep out the sun's damaging rays. Quality window tint film also blocks the harmful and dangerous UV rays that not only are the rays that cause cancer, but are also the most damaging to your car's interior.
In addition these films also keep out the infra red rays that are the source of heat build up in your car. The exact amount of light reflected and heat kept out depends upon the tint that you choose. Before choosing window tint for your vehicle check the local laws in your area, some cities even have municipal ordinances that super cede state laws.
