Key contribution

Saint-Gobain offers a variety of solar control glass solutions to keep interiors more comfortable by preventing excessive heat build-up in sunny weather.


To encourage the establishment of optimal conditions for hygrothermal comfort in cooling mode.

Detailed requirement

Defining/achieving an appropriate temperature level in the spaces, ensuring air speed that does not adversely affect comfort, controlling solar gains and in particular localized discomfort due to heat radiation, controlling of thermal environment by users and hygrometry in sensitive spaces.

Our contribution

8.4.3 Control solar gains and in particular localized discomfort due to heat radiation.

Occupants living in sunny countries can use solar control or thermally efficient glass to avoid heat from entering the building. This glass greatly helps in reducing conduction solar gains in summer. The glass manufactured is either tinted or has a metallic coating, which helps to absorb the radiation and reduce the transmission of heat to a great level.

Also, before installing the glass, it is important to consider the Solar Heat Gain Coefficient (SHGC), which measures the ability of a window or a façade to transmit solar energy into a room.
