Windows & Doors in Fountain Valley Homes
Typical homes in Fountain Valley: mostly 1960s and '70s single-family tracts.
Fountain Valley's well-kept 1960s–70s homes are prime for a first or second window replacement. Homes along the 405 often add laminated glass on the freeway side.
The marine layer keeps Fountain Valley mild most of the year, but afternoon sun on west- and south-facing walls still drives heat gain, so Low-E glass with a low solar heat gain rating keeps those rooms comfortable.
Homes near the I-405 often add laminated acoustic glass on the noisy side of the house.
