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 One Montgomery Tower in San Francisco, 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.
Inland California cities experience some of the highest solar irradiance in the country. Combined with older single-pane window stock, this creates strong demand for low-e retrofit and solar control films.
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.
Non-metallic ceramic particles reject heat without interfering with signals or views.
