Energy-Efficient Windows for Orange Homes
Summer afternoons in Orange regularly reach the 90s, so a Low-E glass package with a low solar heat gain coefficient (SHGC) makes the biggest difference in comfort and air-conditioning costs. Replacing single-pane or early clear dual-pane glass is the single biggest comfort upgrade most Orange homes can make.
Homes near the 55, the 57 and the 22 often add laminated acoustic glass on the noisy side of the house.
