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 Altadena Energy & Solar in Pasadena, 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.
Anti-reflective film is the most targeted solution for glare: it reduces peak window luminance without significantly cutting total light transmission. Best for rooms where screen visibility is the primary concern.
Blocks high-heat solar wavelengths to reduce interior temperatures and UV exposure.
