Why This Matters
UV radiation is responsible for 40–60% of interior fading. It passes through standard glass almost unimpeded — clear glass blocks almost no UV. Window film changes that equation completely.
Near Sha'ar Zahav in San Francisco, 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.
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
The cost of residential window film installation ranges from $8–$20 per square foot installed, depending on film grade and window complexity. Most homes see full payback within 3–5 years.
Solar control film addresses both heat gain and glare. It's the right choice when you want to reduce cooling costs AND improve comfort. Slightly more visible from outside than anti-reflective film.
Retrofits existing glass with a low-emissivity coating for improved thermal performance.
