Why This Matters
Glare is caused by the high luminance contrast between a bright window and the surrounding wall. Window film reduces that contrast by cutting the peak luminance without eliminating natural light.
Near HCI Solar 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 California climate — 260+ sunny days per year in most regions — means solar heat gain is a persistent challenge. Window film addresses it at the source, without blocking your view.
The Solution
Window film works in both directions: it reduces solar heat gain in summer and helps retain interior heat in winter — making it a year-round performance upgrade.
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.
Blocks high-heat solar wavelengths to reduce interior temperatures and UV exposure.
