The measure of solar heat gain is called the solar heat gain coefficient (SHGC) and is expressed as a decimal between 0 and 1—The lower the SHGC, the less solar gain admitted into a building

Maximize energy savings with an SHGC as low as .04

Control heat transfer without the need for special tints or coatings, like vision glazing

Improve solar heat gain control by as much as 900% compared to traditional insulated glass units

Kalwall can provide a range of SHGCs suitable for a particular application and climate
