Energy Star Rated Windows for South Carolina Homes

Energy Star rated windows make more sense in South Carolina than many homeowners expect, especially once summer heat, sticky humidity, and long stretches of sun start pushing the cooling system hard.

Vinyl is usually the lower-cost option and resists moisture well. Fiberglass tends to be stiffer, handles heat better, and often lasts longer in demanding conditions.
