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 Delaware Children's Museum in Wilmington, west-facing windows at low afternoon sun angles drive the highest interior temperature increases. This is especially problematic for home office installations, which glare control and uv protection are critical for home offices with screen-facing windows.
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.
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.
Blocks high-heat solar wavelengths to reduce interior temperatures and UV exposure.
