Why This Matters
Heat gain through glass is cumulative. A room that gains 5°F per hour through unfilmed windows will be 15–20°F above set point by mid-afternoon — forcing the HVAC system to work significantly harder.
Near LBCC Electrical Program in Long Beach, west-facing windows at low afternoon sun angles drive the highest interior temperature increases. 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
Ceramic film is the premium choice for homes where view clarity and signal transparency are priorities. Non-metallic particles absorb heat without the mirror effect of metallic films.
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.
Retrofits existing glass with a low-emissivity coating for improved thermal performance.
