Innovative heat and light protection, made simple

Gradual sunshading with electronically tintable glass

VELUX roof windows with SageGlass® system provides sunshading at the touch of a button thanks to its electrochromic coating, which darkens the glass without obstructing the view. A choice of  levels of tinting offers a pleasant room temperature and sun and glare protection no matter the intensity of the sun.

Excellent heat protection – by darkest tinting g = 0.04

  • Four levels of tinting on demand
  • Optimises daylight penetration without heat gain
  • Avaiable for GGL/GGU in sizes MK04, MK06 and SK06

SageGlass® by Saint-Gobain is electronically tintable glass which allows sunlight to be controlled without the need for external blinds or roller shutters.

Glare and heat are kept under control while allowing an unobstructed view of the outdoors.

Four-step easy operation

The VELUX Electrochrome roof window comes complete with a four-step switch* and 15 m long cable. A scale of coloured LED light clearly shows which level of tinting is active.

* Not compatible with VELUX INTEGRA® and io-homecontrol.
