Easy to use shrink film to help seal out cold air and prevent heat loss.
Eliminate condensation, cold drafts, and heat loss. A hair dryer shrinks the window insulator film to form a smooth, tight, and transparent barrier against the weather. Double-sided tape securely holds the plastic film in place. The film lasts 15 months and completely breaks down in 24 months to help reduce the effect of single-use plastics.
