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 West High School Football Field in Torrance, energy-efficient double-pane glass with low-e coatings can be enhanced further with retrofit film. 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
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.
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.
