What Drives Window Film Demand in This Area
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.
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.
How Low-E Retrofit Window Film Works
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.
