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 General Roofing Co. in Berkeley, south- and west-facing windows receive the most direct solar load and benefit most from film. This is especially problematic for single-family home installations, which the most common residential application; window film reduces heat gain and protects furnishings.
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
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.
