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 Berkeley Law Admissions Office in Berkeley, energy-efficient double-pane glass with low-e coatings can be enhanced further with retrofit 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.
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.
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.
Blocks high-heat solar wavelengths to reduce interior temperatures and UV exposure.
