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 ISKCON Berkeley in Oakland, west-facing windows at low afternoon sun angles drive the highest interior temperature increases. This is especially problematic for luxury residence installations, which high-end homes require premium ceramic or spectrally selective films that preserve view clarity.
Inland California cities experience some of the highest solar irradiance in the country. Combined with older single-pane window stock, this creates strong demand for low-e retrofit and solar control films.
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.
