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 Sunlight Electri-Cal Solutions 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.
Inland California cities experience some of the highest solar irradiance in the country. Combined with older single-pane window stock, this creates strong demand for low-e retrofit and solar control films.
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.
