M-d Building Products Polar Block Indoor Window Shrink Film 42 In. L X 62 In. W 3 Sheet

The M-D Shrink and Seal Indoor Window Insulation Kit is a practical solution for reducing heating costs and improving comfort during cold weather. This three-window pack uses clear plastic film to seal air leaks around window frames, blocking drafts and minimizing heat loss. By creating an insulating air barrier, the kit helps your heating system work more efficiently and maintains warmer indoor temperatures where you need them most.

The shrink film applies easily with a standard hair dryer, shrinking tight and wrinkle-free for a nearly invisible seal that adapts to flat window frames. The included double-sided mounting tape makes installation straightforward, and the clear film design keeps your view unobstructed while providing an effective thermal barrier against cold air infiltration.
