M-d Building Products Polar Block Indoor Window Shrink Film 42 In. L X 62 In. W 9 Sheet

This indoor window insulation kit uses clear shrink film to block cold-air drafts and reduce heat loss through window glass. Winter weather and temperature swings can let precious heated air escape through windows, driving up energy costs and creating uncomfortable drafts and frost buildup. The M-D Building Products shrink film creates a transparent thermal barrier that seals windows without blocking natural light or views.

The heavy-duty, crystal-clear plastic sheet fits standard windows up to 42 by 62 inches without trimming or waste. The convenient pack includes enough film for 6 windows, making it ideal for insulating multiple rooms or preparing your entire home for cold months. Installation is straightforward: apply the included mounting tape around the window frame, attach the film, and use a hairdryer to shrink it tight and wrinkle-free for a professional seal.
