Adaptive Sun Control: Transitional Window Film

Maximize comfort and protection without ever touching a blind. For too long, homeowners have fought a constant battle against the sun, toggling between washed-out screens and a dark, shuttered house just to stay comfortable.

CoolVu provides professional installation of Transitional window films in Princeton, NJ and surrounding areas, serving residential and commercial properties in Hamilton, East Windsor, Dayton, and Trenton, as well as communities throughout Mercer County, Middlesex County, Somerset County and Central New Jersey.

Just like photochromic eyeglasses that darken when you step outside, this film is also a "Smart Tint," utilizing advanced molecular technology to adapt its tint level based on the intensity of the sun.

The film is embedded with light-sensitive photochromic molecules. When these molecules are hit by direct UV (ultraviolet) rays, they undergo a chemical reaction that causes them to expand and darken.

During peak sun: The film darkens to its maximum tint, aggressively blocking heat and blinding glare.
On cloudy days or at night: As UV levels drop, the molecules return to their original state, and the film becomes virtually clear again

Unlike standard films that remain one shade permanently, Transitional Films are dynamic. They constantly work to provide the perfect balance of light and sun protection throughout the entire day.
