What Drives Window Film Demand in This Area
California's Title 24 energy code sets minimum window performance standards for new construction. Window film can bring older homes up to — and beyond — those standards without window replacement.
California's combination of high solar intensity, clear skies, and mild winters makes residential window film a year-round performance upgrade — not just a summer fix.
How Low-E Retrofit Window Film Works
