Why This Matters
The afternoon sun angle in Southern California between June and September is low enough to drive direct solar radiation deep into west-facing rooms. Standard window treatments block the view; film blocks the heat.
Near The Tech Interactive in San Jose, energy-efficient double-pane glass with low-e coatings can be enhanced further with retrofit film. This is especially problematic for multi-family residence installations, which condos and apartment buildings benefit from film to reduce hvac load and improve tenant comfort.
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
Residential window film is the most targeted solution for solar heat gain: it addresses the problem at the source — the glass — rather than compensating with more cooling.
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.
Non-metallic ceramic particles reject heat without interfering with signals or views.
Climate & Solar Performance
Properties near The Tech Interactive in Downtown San Jose, San Jose experience low-e glass performance conditions that make window film particularly effective. Ceramic Window Film is specifically engineered to address this solar exposure.
