Energy-Efficient Windows for San Juan Capistrano Homes
The marine layer keeps San Juan Capistrano 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. Replacing single-pane or early clear dual-pane glass is the single biggest comfort upgrade most San Juan Capistrano homes can make.
Homes near the I-5 and the railroad line through town often add laminated acoustic glass on the noisy side of the house.

What the ratings mean
Every window carries an NFRC label. U-factor measures how well the window insulates (lower is better). Solar heat gain coefficient (SHGC) measures how much of the sun's heat gets through (lower is better in Southern California). Visible transmittance tells you how much daylight comes in. We'll show you these numbers for every window we quote.
