Windows & Doors in Los Alamitos Homes
Typical homes in Los Alamitos: mostly 1950s and '60s single-family homes.
Los Alamitos is a small city of mostly 1950s–60s homes. Being next to the Joint Forces Training Base and the 605 makes acoustic glass a popular upgrade for bedrooms.
The marine layer keeps Los Alamitos 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-605 and activity at the Joint Forces Training Base often add laminated acoustic glass on the noisy side of the house.
