Energy-Efficient Windows for Aliso Viejo Homes
The marine layer keeps Aliso Viejo 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 Aliso Viejo homes can make.
Homes near the 73 Toll Road and Aliso Creek Road often add laminated acoustic glass on the noisy side of the house.
Many Aliso Viejo neighborhoods have HOA or architectural review guidelines for frame colors, grid patterns and door styles — we provide product specs and drawings for your approval application.

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.
