Windows & Doors in Westminster Homes
Typical homes in Westminster: mostly 1950s and '60s single-family homes.
Westminster's 1950s–60s homes often still have original aluminum sliders. Retrofit vinyl windows are the most cost-effective upgrade, and homes near the 405 benefit from acoustic glass.
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.
