Aluminum Windows for Lake Forest Homes
Older aluminum windows conduct heat and don't meet today's energy code, but modern aluminum windows use a thermal break — an insulating barrier inside the frame — to meet California requirements. Their thin profiles and large glass areas suit contemporary and mid-century modern homes.
Summer afternoons in Lake Forest regularly reach the 90s, so a Low-E glass package with a low solar heat gain coefficient (SHGC) makes the biggest difference in comfort and air-conditioning costs.
Many Lake Forest 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.
