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 Seattle Center in Shoreline, south- and west-facing windows receive the most direct solar load and benefit most from film. 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.
Southern California's Santa Ana wind conditions create periods of exceptionally clear, dry air that amplify solar intensity. During these events, unfilmed windows can drive interior temperatures 15–20°F above set point.
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.
Solar control film addresses both heat gain and glare. It's the right choice when you want to reduce cooling costs AND improve comfort. Slightly more visible from outside than anti-reflective film.
Retrofits existing glass with a low-emissivity coating for improved thermal performance.
