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 Kehilla Community Synagogue in Berkeley, 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.
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.
Climate & Solar Performance
Properties near Kehilla Community Synagogue in Silverado Berkeley Memory Care Community, Berkeley experience afternoon heat gain conditions that make window film particularly effective. Anti-Reflective Window Film is specifically engineered to address this solar exposure.

Installation Guide
The best time to schedule installation is in the morning, before the glass heats up. Hot glass causes the slip solution to evaporate too quickly, making it harder to position the film correctly.
