Why This Matters
Heat gain through glass is cumulative. A room that gains 5°F per hour through unfilmed windows will be 15–20°F above set point by mid-afternoon — forcing the HVAC system to work significantly harder.
Near As-Salam Mosque in Berkeley, south- and west-facing windows receive the most direct solar load and benefit most from film. This is especially problematic for multi-family residence installations, which condos and apartment buildings benefit from film to reduce hvac load and improve tenant comfort.
Southern California's Santa Ana wind conditions create periods of exceptionally clear, dry air that amplify solar intensity. During these events, unfilmed windows can drive interior temperatures 15–20°F above set point.
The Solution
Ceramic film is the premium choice for homes where view clarity and signal transparency are priorities. Non-metallic particles absorb heat without the mirror effect of metallic films.
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.
Blocks high-heat solar wavelengths to reduce interior temperatures and UV exposure.
