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 SunPower® in Berkeley, california's 260+ sunny days per year make solar control film a year-round performance upgrade. 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.
California's drought-resistant landscaping trend has reduced shade tree coverage in many neighborhoods. Homes that previously relied on mature trees for solar shading are now prime candidates for window film.
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.
Ceramic film is the premium option: non-metallic, signal-transparent, and highly effective at blocking solar energy. It costs 20–40% more than standard films but offers superior clarity and a longer lifespan.
Retrofits existing glass with a low-emissivity coating for improved thermal performance.
