Why This Matters
Low-e coatings on double-pane windows are optimized for winter heat retention. In summer, they still allow significant solar heat gain. Window film corrects this seasonal imbalance.
Near Save a Lot Solar in Berkeley, west-facing windows at low afternoon sun angles drive the highest interior temperature increases. This is especially problematic for single-family home installations, which the most common residential application; window film reduces heat gain and protects furnishings.
California's combination of high solar intensity, clear skies, and mild winters makes residential window film a year-round performance upgrade — not just a summer fix.
The Solution
Low-e retrofit film is the most cost-effective upgrade for older single-pane windows. It adds a low-emissivity layer that dramatically improves thermal performance without full window replacement.
Hybrid films combine ceramic particles with metallic layers for maximum heat rejection. They're the right choice for extreme solar exposures or homes with very large west-facing glass areas.
Reduces glare and diffuses focused solar energy to protect interiors and improve comfort.
