Key contribution

Through its efficient insulation and dynamic solar control properties, SageGlass can help achieve thermal comfort during the winter by harnessing the sun’s heat while managing glare at the same time. 


To foster the establishment of optimal conditions for hygrothermal comfort in heating mode.

Detailed requirement

Defining/achieving an appropriate temperature level within spaces, ensuring temperature stability during occupancy periods and air velocity that does not adversely affect comfort and controlling of thermal environment by users and of hygrometry.

Our contribution

  • 8.2.1. Define/achieve an appropriate temperature level within spaces 
  • 8.2.2. Ensure temperature stability during occupancy periods 
  • 8.2.4. Control of thermal environment by users 

With its efficient insulation and dynamic solar control properties, SageGlass helps to achieve comfortable temperatures during the heating season by letting in the sun’s heat and managing glare. It’s important to note that SageGlass® should be mounted in a high-performance airtight framing system with excellent insulation properties. And to achieve higher insulation performance, you can make use of the triple-pane configuration options available.
The user can take control of SageGlass to manage the thermal environment at any time. SageGlass tint control can be done on an entire row of windows, a single window, or even on areas within the same window. This flexibility is a major asset for the creation of specific thermal zones within a building.
