Why This Matters
Low-e glass was a major step forward in window efficiency. But it has limits. Low-e retrofit film extends that performance further, adding a second emissivity layer that existing glass lacks.
Near Sutter Santa Rosa Regional Hospital in Santa Rosa, 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
Most residential window film installations are completed in a single day. The film cures fully within 30 days, after which performance is at its rated specification.
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.
Retrofits existing glass with a low-emissivity coating for improved thermal performance.
