What is the difference between SHGC & SC of a glass?

WebFeb 15, 2024 · The solar heat gain coefficient (SHGC) is a ratio that defines the amount of solar energy that reaches a glazing assembly (including both the glass and frame) with the amount that gets through to the inside. It represents the ability of a glazing assembly to resist heat gain from direct solar radiation. A high SHGC indicates poor resistance. WebApr 1, 2024 · As the weakest thermal component of the building envelope, glazing window allows for a large amount of solar heat gain and its solar heat gain coefficient largely affects the building's OTTV.
