Why This Matters
West-facing windows receive the lowest sun angle in the afternoon — the same angle that drives the highest solar intensity per square foot of glass. This is why west-facing rooms overheat first.
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 home office installations, which glare control and uv protection are critical for home offices with screen-facing windows.
California's combination of high solar intensity, clear skies, and mild winters makes residential window film a year-round performance upgrade — not just a summer fix.
The Solution
Quality window films carry 10–15 year manufacturer warranties. That's longer than most window treatments and comparable to the lifespan of the windows themselves.
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.
Blocks high-heat solar wavelengths to reduce interior temperatures and UV exposure.
