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 Tork Systems, Inc. in Berkeley, south- and west-facing windows receive the most direct solar load and benefit most from film. 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.
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 Tork Systems, Inc. in HOA Organizers, Inc., Berkeley experience south & west exposure conditions that make window film particularly effective. Ceramic Window Film is specifically engineered to address this solar exposure.
Effective against south & west exposure
Rated for historic or older home protection

Installation Guide
The best time to schedule installation is in the morning, before the glass heats up. Hot glass causes the slip solution to evaporate too quickly, making it harder to position the film correctly.
