Why This Matters
Single-pane windows — still common in California homes built before 1980 — have almost no thermal resistance. Low-e retrofit film can cut their solar heat gain by 40–60% at a fraction of the cost of replacement.
Near Downtown Berkeley 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 drought-resistant landscaping trend has reduced shade tree coverage in many neighborhoods. Homes that previously relied on mature trees for solar shading are now prime candidates for window film.
The Solution
The installation process is non-invasive: clean the glass, apply the film with a slip solution, squeegee out air pockets, and trim to fit. No construction, no permits, no disruption.
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.
