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 Berkeley High Stadium in Berkeley, south- and west-facing windows receive the most direct solar load and benefit most from film. This is especially problematic for luxury residence installations, which high-end homes require premium ceramic or spectrally selective films that preserve view clarity.
California's drought-resistant landscaping trend has reduced shade tree coverage in many neighborhoods. Homes that previously relied on mature trees for solar shading are now prime candidates for window film.
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.
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.
