Why This Matters
Solar heat gain through windows accounts for 25–30% of residential cooling load in California homes. That's the single largest controllable source of summer heat gain.
Near Mt. Hood Community College in Gresham, california's 260+ sunny days per year make solar control film a year-round performance upgrade. 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 marine layer that covers coastal California in the morning burns off by midday, leaving afternoons with intense, direct sunlight. West-facing rooms without film are at their hottest between 2pm and 5pm.
The Solution
Film selection for south- and west-facing windows should prioritize solar heat rejection. For north-facing windows, UV protection and glare control are typically the primary goals.
Low-e retrofit film is specifically designed for older single-pane windows. It adds a low-emissivity layer that dramatically improves thermal performance — the most cost-effective upgrade for pre-1980 California homes.
Reduces glare and diffuses focused solar energy to protect interiors and improve comfort.
