Why Low-E Windows Are Popular in South Carolina Homes

Homeowners in South Carolina keep choosing low-E windows because they tackle one of the state's biggest problems, heat gain, while still letting in natural light.

For homeowners dealing with noise along busier corridors, low-E glass can also be part of a broader upgrade package that includes better sealing and thicker insulated panes.
