Why This Matters
Glare is caused by the high luminance contrast between a bright window and the surrounding wall. Window film reduces that contrast by cutting the peak luminance without eliminating natural light.
Near Financial District Hardware 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.
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
Window film works in both directions: it reduces solar heat gain in summer and helps retain interior heat in winter — making it a year-round performance upgrade.
Anti-reflective film is the most targeted solution for glare: it reduces peak window luminance without significantly cutting total light transmission. Best for rooms where screen visibility is the primary concern.
Retrofits existing glass with a low-emissivity coating for improved thermal performance.
