Why This Matters
West-facing windows receive the lowest sun angle in the afternoon — the same angle that drives the highest solar intensity per square foot of glass. This is why west-facing rooms overheat first.
Near Solarwinds in Concord, south- and west-facing windows receive the most direct solar load and benefit most from film. 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
Quality window films carry 10–15 year manufacturer warranties. That's longer than most window treatments and comparable to the lifespan of the windows themselves.
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.
