Why This Matters
Low-e glass was a major step forward in window efficiency. But it has limits. Low-e retrofit film extends that performance further, adding a second emissivity layer that existing glass lacks.
Near Frank Lloyd Wright Home & Studio in Chicago, energy-efficient double-pane glass with low-e coatings can be enhanced further with retrofit film. 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
Most residential window film installations are completed in a single day. The film cures fully within 30 days, after which performance is at its rated specification.
Perforated film solves the privacy-versus-light tradeoff for street-facing rooms. The micro-hole pattern maintains outward visibility from inside while blocking the view from outside during daylight hours.
Non-metallic ceramic particles reject heat without interfering with signals or views.
Climate & Solar Performance
