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.
Peak cooling load in homes is driven primarily by solar heat gain through windows. Window film reduces that load at the source — before it enters the home — which is why it consistently delivers the fastest payback of any home comfort upgrade.
How Solar Control 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.
For maximum heat rejection, ceramic or nano-ceramic solar control film outperforms standard dyed or metallic films in every category: heat rejection, UV blocking, visible light transmission, and longevity.
