To understand the energy efficiency rating of your glass, the SHGC and U-Value are two commonly used measurements. We’ve provided a brief explanation to help you select the right option for your home.
What is a Solar Heat Gain Coefficient (SHGC)?
SHGC stands for Solar Heat Gain Coefficient. Measuring the SHGC helps us understand how much solar heat is gained through the glass window or door as a result of direct sunlight. When sunlight hits the glass, there is a portion of sunlight that is reflected. The remainder is either absorbed by the glass or transmitted through the glass. The SHGC is a percentage measure of solar heat gain that is transmitted through the glass. It is measured as a number between 0 and 1, with a higher co-efficient meaning that more heat gain will occur. More information can be found here
