The total amount of heat transmitted through the glass into the inside of the building is represented by the SHGC. Each glass type has a different SHGC. The lower the number the better the solar control performance of that particular glass product.

For example, our 4mm VFloat™ Clear glass has an SHGC of 0.85, whilst ComfortPlus™ has an SHGC between 0.57 and 0.60 depending on the colour.
