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 Fox Point State Park in Newark, 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.
The marine layer that covers coastal California in the morning burns off by midday, leaving afternoons with intense, direct sunlight. West-facing rooms without film are at their hottest between 2pm and 5pm.
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.
Low-e retrofit film is specifically designed for older single-pane windows. It adds a low-emissivity layer that dramatically improves thermal performance — the most cost-effective upgrade for pre-1980 California homes.
Retrofits existing glass with a low-emissivity coating for improved thermal performance.
