Windows & Doors in Placentia Homes
Typical homes in Placentia: mostly 1960s–1980s single-family homes.
Placentia's 1960s–80s homes are ready for their first window replacement. Hot afternoons make west-facing rooms a priority for Low-E glass.
Summer afternoons in Placentia 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 and the rail line through town often add laminated acoustic glass on the noisy side of the house.
