Window Film Needs for This Home Type
Single-pane home windows have an R-value of about 1. Double-pane is around R-2. Low-e retrofit film can improve that to R-3 or better — a meaningful improvement for older homes that can't justify full window replacement.
Inland residential markets experience some of the highest solar irradiance in the country. Window film is one of the most cost-effective ways to manage that heat load without replacing windows or oversizing AC equipment.
How Decorative Window Film Works
The right film for your home balances comfort with aesthetics — typically a neutral-appearance solar control film with moderate VLT and high heat rejection that satisfies both energy performance and curb appeal.
Low-e retrofit film is the most cost-effective upgrade for single-pane home windows: it adds an insulating layer that improves thermal performance and reduces heating and cooling costs without the expense of full window replacement.
