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 Potrero Energy in San Francisco, south- and west-facing windows receive the most direct solar load and benefit most from film. This is especially problematic for home office installations, which glare control and uv protection are critical for home offices with screen-facing windows.
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 at a fraction of the cost of window replacement.
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.
Non-metallic ceramic particles reject heat without interfering with signals or views.
