This switchable privacy film applies directly to existing glass with a self-adhesive layer. It changes from transparent to opaque with electrical current, providing daytime privacy while allowing light when needed. It’s designed for windows, doors, and partitions.

It helps reflect heat and reduce glare, contributing to energy savings. Best for: ground-floor rooms or street-facing spaces needing ongoing daytime privacy.

Updated backing grids help with clean, precise cuts. The film itself has no inherent color; the rainbow effect emerges from sunlight dispersion. Best for: sun-facing windows where you want color play and privacy without altering interior light much. Caution: the effect is sunlight-driven, so timing and placement matter for the best look.
