Why This Matters
Low-e glass was a major step forward in window efficiency. But it has limits. Low-e retrofit film extends that performance further, adding a second emissivity layer that existing glass lacks.
Near Got Watts? in San Francisco, 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
Most residential window film installations are completed in a single day. The film cures fully within 30 days, after which performance is at its rated specification.
Solar control film addresses both heat gain and glare. It's the right choice when you want to reduce cooling costs AND improve comfort. Slightly more visible from outside than anti-reflective film.
Reduces glare and diffuses focused solar energy to protect interiors and improve comfort.
Climate & Solar Performance
Properties near Got Watts? in Mission District, San Francisco experience low-e glass performance conditions that make window film particularly effective. Anti-Reflective Window Film is specifically engineered to address this solar exposure.
