Why install energy-efficient windows?

Save on both heating and cooling bills. Keystone installs windows with low-E coatings, gas-fills, and insulating spacers and frames, which keep the cold out and the heat in. Low-E coatings can also help reduce solar heat in the summer.

Improve comfort in your home. Create your comfort. Energy-efficient windows have a lower U-factor than most, resulting in moderate window temperatures and fewer cold drafts. Conversely, the lower solar heat gain coefficient (SHGC) helps block heat from the summer sun, keeping your home comfortable year-round.

Prevent fading to your valuable home furnishings. All Keystone windows help block harmful UV rays with a glass or plastic film built into the window.
