Low-E Glass and Solar Heat Gain Coefficient for Winter Haven Homes

How Low-E Glass Helps In Winter Haven

In Winter Haven, the first thing most homeowners notice is not deep cold, it is how hard the sun works on a house from March through October.

For homes in Winter Haven, that matters because sunlight is not just bright, it is a heat load.

Understanding Solar Heat Gain Coefficient

The lower the SHGC, the less solar heat the glass admits.
