How Window Films Work

How exactly do window films work?

The specialty film market is bursting. By 2019, it’s expected to reach close to $8 billion with a healthy portion of that from solar and safety window films. The surge is primarily due to customers being more aware of the films’ safety abilities and low cost of installation compared to removing old and installing specialty windows.

You may already know that Michigan Glass Coating’s 3M sun control films block up to 99 percent of UV light and close to 80 percent of the sun’s heat. You may even know there are several safety films you can purchase to help prevent glass from shattering when it breaks. Or, that you can purchase decorative window films to create beautiful privacy screens or imagery.

But how do window films exactly work? Typically, films are made of polyester and modified with substances that absorb, scatter and reflect harmful lights. They also come in a variety of thicknesses. Michigan Glass Coatings offers safety and security window films ranging from 4 mil single layer films to 42 micro-layers of strong, tear-resistant technology.

Manufacturers can apply the UV coating either to the film’s base or surface or inside of the layers. Once constructed, these films are usually applied to the inside of a building which helps the window films last longer.

You may have seen do-it-yourself window film kits, however we highly suggest having a professional install it to ensure it’s applied correctly. These professionals will also be able to answer any questions you have about the glass, such as how long, on average, it takes for the film to completely dry.
