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 Sierra Solar Inc. in Ontario, 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.
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.
Perforated film solves the privacy-versus-light tradeoff for street-facing rooms. The micro-hole pattern maintains outward visibility from inside while blocking the view from outside during daylight hours.
Non-metallic ceramic particles reject heat without interfering with signals or views.
