Why This Matters
Glass is a poor thermal barrier. Even double-pane windows transmit significant solar heat — especially on south- and west-facing exposures where the sun angle is most direct.
Near University of Integrated Sci in Santa Rosa, 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.
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
Professional installation ensures the film is applied without bubbles, gaps, or edge lifting — all of which reduce effectiveness and shorten lifespan.
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.
Retrofits existing glass with a low-emissivity coating for improved thermal performance.
Climate & Solar Performance
