Window Tinting Explained


It is a common misconception that darker films will always work better in terms of heat reduction and UV protection. It is true that a darker shade of tint will always offer better glare reduction than a lighter tint, the reasons for which should be obvious. Allow us to provide more information regarding other aspects of light v’s dark window films to help assist you in your decision making process.


Any window film of reasonable quality, light or dark, has the ability to block out over 99% of all ultra violet radiation. The most prominent reason for this is that the adhesive on these films contains a UV inhibitor to protect it from being broken down under direct sunlight. Therefore, in truth, UV protection is actually only a by-product of the films design. So this should not play any part in the light v’s dark conflict as both methods of tinting will offer the same results in this category.


The most common misrepresentation of window films for your car, is the belief that a darker tint will stop more heat than a lighter one. In many cases, this couldn’t be further from the truth. New technology in the form of ‘spectrally selective films’ is now allowing manufacturers to develop solar film that can target the specific parts of the light spectrum that cause heat (U.V. & Infra Red). These films will be almost transparent and yet stop more heat than any dark coloured tint could ever hope to achieve. Very dark tints are often produced by adding dye to the lamination process (usually mixed in with the bonding adhesive) giving the appearance of a darker look and a more dominant glare reduction. The down side to this process, is that often the dye, made up of Blue, Yellow & Red dyes to produce black, will be affected over time by the suns U.V. radiation, causing the yellow dye to fade away faster than the blue and red. This causes what is often seen on older style cars that appear to have purple coloured tinting.


The introduction of nanotechnology to the window film industry has lead to many breakthroughs in recent years, allowing films that are virtually transparent to offer better heat reduction than much darker films through ‘spectral selection’. This technology allows the film to prevent only certain parts of the total light spectrum to pass through the film. By blocking 99% of U.V. rays, and approx 95% of the Infra Red radiation, this new breed of film is capable of allowing a large amount of visible light to be transmitted while still being able to leave the room, or car very cool inside. Come in and see us for a demonstration.
