Window Replacement for Westminster Homes
Mostly 1950s and '60s single-family homes make up much of Westminster, and many still have original or first-generation windows. The marine layer keeps Westminster 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 and the 22 often add laminated acoustic glass on the noisy side of the house.

Meeting California's energy code
Replacement windows in California must meet Title 24 energy standards. For whole-house projects that generally means a U-factor of 0.30 or lower and a solar heat gain coefficient (SHGC) of 0.23 or lower in Orange County's climate zones. Every window we quote is a dual-pane, Low-E unit that meets the code, and we handle the paperwork and permits where your city requires them.
