Energy-Efficient Windows for Santa Ana Homes
Summer afternoons in Santa Ana 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. Low-E glass also blocks most UV, which protects floors, cabinets and furniture from fading.
Homes near the I-5, the 55, the 22 and John Wayne Airport to the south often add laminated acoustic glass on the noisy side of the house.

What the ratings mean
Every window carries an NFRC label. U-factor measures how well the window insulates (lower is better). Solar heat gain coefficient (SHGC) measures how much of the sun's heat gets through (lower is better in Southern California). Visible transmittance tells you how much daylight comes in. We'll show you these numbers for every window we quote.
