To explain how, we first need to explain various common window tint film constructions. To simplify what can be a complicated topic, there are three primary ways that a window tint is constructed to give it the look and performance characteristics you see and feel on the glass. They are as follows:
- Dyed Window Tint - Essentially, this is a base layer of polyester film that is dyed to the color and darkness desired. Then, a scratch-resistant coating is applied to the exterior surface and and adhesive layer is applied to the interior side that will attach to the glass. There are various ways that a polyester film can be dyed, but for this article those differences are irrelevant. These films typically give a consumer the look they desire, but do not have a great deal of performance when it comes to heat rejecting properties.
- Metal-Hybrid Window Tint - This film is typically constructed when a layer of polyester film has a layer of metal particles attached to it. There are two primary ways to apply this metal layer, but for this article, it is enough to understand that the polyester layer and metal layer are bonded together. This film can also have the polyester layer dyed as above to achieve the desired look of the final product. Like the dyed window tint above, this combination then has a scratch-resistant coating to the exterior surface and and adhesive layer applied to the interior side that will attach to the glass.
