Why This Matters
Solar heat gain through windows accounts for 25–30% of residential cooling load in California homes. That's the single largest controllable source of summer heat gain.
Near Ilum Solar in Sacramento, california's 260+ sunny days per year make solar control film a year-round performance upgrade. 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 combination of high solar intensity, clear skies, and mild winters makes residential window film a year-round performance upgrade — not just a summer fix.
The Solution
Film selection for south- and west-facing windows should prioritize solar heat rejection. For north-facing windows, UV protection and glare control are typically the primary goals.
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.
