How Flat Glass Tint Differs from Automotive Tint
We are sometimes asked if it is possible to use flat glass tinting film – used for home and commercial windows – for tinting car windows. One reason for this question is that you might have some tinting film left over from when you had your home or business windows tinted, or you might prefer the darkness or reflective qualities of flat glass tints.
The short answer to this question is, no. But it is a question that warrants a longer answer that explains how flat glass tint differ from automotive tint.
1. Flat Glass Tint Is Not Regulated
The biggest difference between flat glass tint – sometimes also called architectural tint – and automotive tints is that car window tints are strictly regulated in most countries. While the intended purpose for both is the same – increased privacy, and the blocking of harmful UV rays and excess heat – flat glass tints can be much darker or reflective than automotive tints. This in turn results in them blocking out more light and solar energy, and naturally resulting in much more privacy. But car window tints are regulated, and depending on where you live, they cannot block more than 65 percent of visible light. The reason for this is safety: your safety, and the safety of other road users. Blocking out too much light makes it more difficult for you to see what is happening on the road ahead of you, and around you, worsening at night or in low-light conditions.
2. Flat Glass Tint Does Not Shrink
As the name implies, flat glass tint is only applied to flat or plate glass. With no curves, there is no need for the film material to be able to shrink. Many car windows do have curves, no matter how subtle they are, so the film needs to be able to shrink to ensure a proper fit. This also results in the adhesives used to affix the films differing.
3. The Composition of the Film Is Different
Flat glass tint film reflects heat, while automotive tint films absorb heat. One way this is achieved is through the use of metallic compounds in flat glass tints. These are safe for use when tinting the windows of a residential home or business, but if used on car windows would result in electronic interference. Car window tints are specifically designed to minimise any interference with the electronics in the small confines of a car, but this isn’t an issue in houses and buildings.
While it is definitely not advisable to use flat glass tint on car windows, you should also never consider using automotive tint on home or commercial windows. Automotive tinting film’s ability to shrink and to absorb instead of reflecting heat increase the risk of your home or office windows cracking or shattering.
