Energy-Efficient Windows for Fountain Valley Homes
The marine layer keeps Fountain Valley 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. Low-E glass also blocks most UV, which protects floors, cabinets and furniture from fading.
Homes near the I-405 often add laminated acoustic glass on the noisy side of the house.

Why it matters in Orange County
Inland cities regularly see summer afternoons in the 90s, and west- and south-facing glass is the biggest source of heat gain in most homes. Replacing single-pane or early clear dual-pane glass with modern Low-E glass keeps rooms cooler, reduces fading of floors and furniture, and lets your air conditioner run less.
