Vario Sun is a glass product, that integrates advanced photochromic and thermochromic dual-response technology. Through our proprietary process, it delivers permanent, non-fading performance with no measurable degradation over its service life.

The interlayer automatically tints in response to solar radiation and temperature, darkening under high solar load and elevated temperatures, and returning to a clear state in lower light and cooler conditions.

Operation requires no electrical power, wiring, sensors, or control systems.
This passive, zero-energy dynamic glazing solution reduces solar heat gain, controls glare, and blocks UV radiation while maintaining access to natural daylight. It is available in both laminated glass and IGU Units.
