Switchable film: Instant privacy, dynamic design

Switchable film, the future of privacy, elegance, and innovation, is a revolutionary material that offers you instant privacy with the flick of a switch. This innovative technology provides a modern and elegant solution for both residential and commercial spaces.

How does switchable film work?

At the heart of switchable film is a unique liquid crystal technology. In its “off” state, liquid molecules are randomly dispersed, making the film opaque. When an electrical current is applied, the liquid crystal molecules align, allowing the light to pass through and making the film transparent.

This transition happens instantaneously, providing immediate privacy or openness as desired.
