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 Stu Gordon Stadium in Berkeley, west-facing windows at low afternoon sun angles drive the highest interior temperature increases. This is especially problematic for historic or older home installations, which older single-pane windows benefit most from low-e retrofit film to improve thermal efficiency.
Inland California cities experience some of the highest solar irradiance in the country. Combined with older single-pane window stock, this creates strong demand for low-e retrofit and solar control films.
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 Stu Gordon Stadium in West Berkeley, Berkeley experience afternoon heat gain conditions that make window film particularly effective. Ceramic Window Film is specifically engineered to address this solar exposure.
