Energy Star Rated Windows for South Carolina Homes

In South Carolina, Energy Star rated windows can be one of the more sensible home improvements because they help reduce heat gain without sacrificing natural light.

Old windows often show their age in the summer first. Rooms feel hotter, the air near the glass feels uneven, and cooling costs rise even when nothing else in the house has changed.
