Why This Matters
Perforated film achieves one-way privacy through a simple optical principle: the interior is darker than the exterior during daylight hours, so the pattern is visible from outside but transparent from inside.
Near West Sunset Diamond 1 in San Francisco, energy-efficient double-pane glass with low-e coatings can be enhanced further with retrofit 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 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
Solar control film is the workhorse of residential window film. It blocks 40–70% of solar heat gain while maintaining clear views and natural light.
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.
Non-metallic ceramic particles reject heat without interfering with signals or views.
