Why This Matters
Double-pane windows with low-e coatings perform well in cold climates where retaining heat is the goal. In California's mild winters and hot summers, the priority is solar rejection — which is where window film adds the most value.
Near We Care Solar in Berkeley, west-facing windows at low afternoon sun angles drive the highest interior temperature increases. This is especially problematic for multi-family residence installations, which condos and apartment buildings benefit from film to reduce hvac load and improve tenant comfort.
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
After installation, the film is essentially invisible from inside the home. The exterior may show a slight tint, but view quality and light transmission remain largely unchanged.
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.
Retrofits existing glass with a low-emissivity coating for improved thermal performance.
