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.
California's Title 24 energy code and similar state standards increasingly recognize window film as a qualifying energy efficiency measure. Post-installation energy audits can document heat gain reduction for rebate submissions.
How Privacy 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.
UV protection film is clear or nearly clear — it blocks 99% of UV rays without changing the look of your windows. It's the right choice when fading protection is the priority and you don't want any tint.
