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 ISG Software Research in Bend, energy-efficient double-pane glass with low-e coatings can be enhanced further with retrofit film. This is especially problematic for historic or older home installations, which older single-pane windows benefit most from low-e retrofit film to improve thermal efficiency.
The California climate — 260+ sunny days per year in most regions — means solar heat gain is a persistent challenge. Window film addresses it at the source, without blocking your view.
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.
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.
Reduces glare and diffuses focused solar energy to protect interiors and improve comfort.
