SHGC stands for Solar Heat Gain Co-efficient. A fraction of solar radiation admitted through a window or door (either transmitted directly and/or absorbed) is subsequently released as head inside the home. The lower the SHGC rating of a window the less solar heat it transmits and the greater its ability to block heat gained from the sun in summer. A window / door with a high SHGC rating is more effective at collecting solar heat gain during winter and keeping the home warm. Our windows and doors have a SHGC rating of 0.45
