Windows & Doors in Fullerton Homes
Typical homes in Fullerton: historic 1920s–30s homes near downtown, post-war tracts and hillside custom homes.
Fullerton has historic Spanish and Craftsman homes near downtown, 1950s–60s tracts, and hillside homes in Sunny Hills and Golden Hills. Homes near the downtown rail lines often choose laminated acoustic glass.
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.
Homes near the 57, the 91 and the rail lines through downtown often add laminated acoustic glass on the noisy side of the house.
