Key contribution

Saint-Gobain offers a variety of solar control glass solutions which limits heat gain and therefore, the air conditioning needs. Through the overall shape, orientation, and the size, including its ability to reflect heat, the Saint-Gobain glazing controls the amount of heat allowed to enter the building.


To ensure that zones of occupation benefit from a minimum level of hygrothermal comfort, without cooling system.

Detailed requirement

Ensuring a minimum level of thermal comfort, a sufficient ventilation and controlling the air flow if hygrothermal comfort is achieved by opening windows or doors.

Our contribution

Exposed façade in sunny countries can cause extreme discomfort due to overheating. Hence, it is recommended that occupants' make use of solar control glass to prevent heat from entering the building. The solar control glass is manufactured by tinting or applying a metallic coating. Remember, The online coating offers a varied range of performance and a more neutral appearance for solar protection glass.

To select the most appropriate glazing for rooms with no access to the cooling system, it is necessary 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. The SHGC is commonly referred to as the g-value or solar factor that ranges between 0 to 1. The lower a window’s g-value, the greater its ability to insulate against solar heat build-up.
