Prevent Heat Damage Near PACE Supply, Berkeley — Perforated Window Film Guide

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 PACE Supply in Berkeley, south- and west-facing windows receive the most direct solar load and benefit most from film. This is especially problematic for multi-family residence installations, which condos and apartment buildings benefit from film to reduce hvac load and improve tenant comfort.

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.

Micro-perforated pattern provides one-way privacy and solar control without blocking the view.

Climate & Solar Performance

Properties near PACE Supply in West Berkeley, Berkeley experience south & west exposure conditions that make window film particularly effective. Perforated Window Film is specifically engineered to address this solar exposure.
