Why This Matters
California's Title 24 energy code sets minimum window performance standards for new construction. Window film can bring older homes up to — and beyond — those standards without window replacement.
Near Bering Sea Office Supply and Electronics in Unalaska, west-facing windows at low afternoon sun angles drive the highest interior temperature increases. This is especially problematic for historic or older home installations, which older single-pane windows benefit most from low-e retrofit film to improve thermal efficiency.
The California climate — 260+ sunny days per year in most regions — means solar heat gain is a persistent challenge. Window film addresses it at the source, without blocking your view.
The Solution
Perforated film solves the privacy-versus-light tradeoff. The micro-hole pattern maintains outward visibility from inside while blocking the view from outside during daylight hours.
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.
