The three film grades were created to block up to 99.9 percent of UV rays.

The three films are applied to the outside of glass to reduce thermal stress and can be used on retrofit projects or new construction. According to the company, the films contain no metals, have a thickness less than a Post-it® Note and Exterior PR90 only reduces the amount of sunlight entering a building by, at most, one percent.
