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 Duniway Park Lilac Garden in Gresham, california's 260+ sunny days per year make solar control film a year-round performance upgrade. This is especially problematic for home office installations, which glare control and uv protection are critical for home offices with screen-facing windows.
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
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.
Retrofits existing glass with a low-emissivity coating for improved thermal performance.
