Indoor Window Insulator Kit – Oversized Window with Heat-Shrink Film & Scotch® Mounting Tape

The 3M™ Indoor Window Insulator Kit 2149W-6 is designed to keep cold drafts out and warm air in, helping reduce heating costs throughout the winter season. Featuring crystal-clear heat-shrink film and Scotch® Window Film Mounting Tape, this kit provides a transparent, wrinkle-free seal that stays in place all season long. The film can increase the R-value of a single pane of glass by up to 90%, while preventing condensation and frost buildup. Quick and easy to install with just a hair dryer, the kit fits one extra-large 6'8" x 19.5' indoor window and is backed by a 1-year limited warranty for dependable home energy savings.
