Energy-Efficient Windows for Fullerton Homes
Summer afternoons in Fullerton 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. West-facing living rooms and upstairs bedrooms are usually where Fullerton homeowners notice the difference first.
Homes near the 57, the 91 and the rail lines through downtown often add laminated acoustic glass on the noisy side of the house.

Why it matters in Orange County
Inland cities regularly see summer afternoons in the 90s, and west- and south-facing glass is the biggest source of heat gain in most homes. Replacing single-pane or early clear dual-pane glass with modern Low-E glass keeps rooms cooler, reduces fading of floors and furniture, and lets your air conditioner run less.
