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 Exploratorium in Berkeley, energy-efficient double-pane glass with low-e coatings can be enhanced further with retrofit film. 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.
Reduces glare and diffuses focused solar energy to protect interiors and improve comfort.
Climate & Solar Performance
Properties near Exploratorium in West Berkeley, Berkeley experience low-e glass performance conditions that make window film particularly effective. Anti-Reflective Window Film is specifically engineered to address this solar exposure.
