Prevent Heat Damage Near PIER 39, Berkeley — Low-E Retrofit Window Film Guide

Why This Matters

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 without window replacement.

Near PIER 39 in Berkeley, south- and west-facing windows receive the most direct solar load and benefit most from 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.

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

Perforated film solves the privacy-versus-light tradeoff. The micro-hole pattern maintains outward visibility from inside while blocking the view from outside during daylight hours.
