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 Master Guild in Berkeley, west-facing windows at low afternoon sun angles drive the highest interior temperature increases. 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 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
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.
Micro-perforated pattern provides one-way privacy and solar control without blocking the view.
