Key contribution
Saint-Gobain Glass delivers a large range of solar control glass with excellent light transmittance as well as performing shading systems to help occupants manage uncomfortable glare, while maximizing the amount of natural light in buildings. This is in keeping with our principles of promoting green building and optimizing energy efficiency.
Aim
To avoid glare from the sun by blocking or reflecting direct sunlight away from occupants.
Detailed requirement
Part 1: View Window Shading
At least one of the following is present for all glazing less than 2.1 m [7 ft] above the floor in regularly occupied spaces:
- Interior window shading or blinds that are controllable by the occupants or set to automatically prevent glare.
- External shading systems that are set to prevent glare.
- Variable opacity glazing, such as electrochromic glass, which can reduce transmissivity by 90% or more.
Part 2: Daylight Management
At least one of the following is required for all glazing greater than 2.1 m [7 ft] above the floor in regularly occupied spaces:
- Interior window shading or blinds that are controllable by the occupants or set to automatically prevent glare.
- External shading systems that are set to prevent glare.
- Interior light shelves to reflect sunlight toward the ceiling.
- A film of micromirrors on the window that reflects sunlight toward the ceiling.
- Variable opacity glazing, such as electrochromic glass, which can reduce transmissivity by 90% or more.

Our contribution

Used in double or triple glazing, CLIMAPLUS/CLIMATOP SCREENS manage disruptive glare emanating from windows, while letting in lots of natural light. The glazing integrates an electrically operated venetian blind within the cavity, providing efficient solar and glare control. Modern control technology allows the occupants to adjust the louvres that can be automatically operated via switch or remote control. Thanks to its variable controls for raising, lowering and turning the louvres, the desired level of solar control can be provided.
