Why This Matters
Solar control film works across the full solar spectrum — blocking near-infrared heat, visible light glare, and UV radiation simultaneously. No other window treatment addresses all three.
Near Middle Harbor Shoreline Park in Berkeley, west-facing windows at low afternoon sun angles drive the highest interior temperature increases. This is especially problematic for home office installations, which glare control and uv protection are critical for home offices with screen-facing windows.
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
The right film for your home depends on three factors: window orientation, glass type, and what you're primarily trying to solve. A qualified installer can assess all three in a single visit.
Low-e retrofit film is specifically designed for older single-pane windows. It adds a low-emissivity layer that dramatically improves thermal performance — the most cost-effective upgrade for pre-1980 California homes.
Retrofits existing glass with a low-emissivity coating for improved thermal performance.
