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 Musée Mécanique in Berkeley, west-facing windows at low afternoon sun angles drive the highest interior temperature increases. This is especially problematic for luxury residence installations, which high-end homes require premium ceramic or spectrally selective films that preserve view clarity.
California's Title 24 energy code sets minimum window performance standards for new construction. Window film can bring older homes up to — and beyond — those standards at a fraction of the cost of window replacement.
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.
