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 Hammer Throw in Pomona, west-facing windows at low afternoon sun angles drive the highest interior temperature increases. This is especially problematic for single-family home installations, which the most common residential application; window film reduces heat gain and protects furnishings.
Southern California's Santa Ana wind conditions create periods of exceptionally clear, dry air that amplify solar intensity. During these events, unfilmed windows can drive interior temperatures 15–20°F above set point.
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.
Ceramic film is the premium option: non-metallic, signal-transparent, and highly effective at blocking solar energy. It costs 20–40% more than standard films but offers superior clarity and a longer lifespan.
Blocks high-heat solar wavelengths to reduce interior temperatures and UV exposure.
