About This

50% Thicker for Improved Winter Insulation: Made with 1.2 mil thickness—compared to standard 0.8 mil shrink films—this window insulation film delivers 50% more strength and better heat retention. Helps block cold drafts, reduce heat loss, and keep indoor spaces warmer throughout winter
Covers Up to 10 Standard Windows: Sized 63 × 433 inches, this window insulation kit fits up to ten 3 × 5 ft windows. Ideal for insulating multiple rooms such as living rooms, bedrooms, and home offices, offering a practical solution for whole-home winterizing
Stronger Film for Long-Lasting Performance: The upgraded, thicker plastic window covering resists tearing and puncturing better than standard films. Built to last through the winter season, it helps keep windows sealed and supports lower heating costs
Easy Heat-Shrink Installation: Simply cut to size, secure with the included tape, and use a standard household hair dryer to shrink the film tight. Achieve a smooth, wrinkle-free finish in minutes without special tools
Clear & Invisible Look: Made from premium POF material, this clear window film remains fully transparent. Once heat-shrunk, it tightens evenly without blocking light or obstructing your view
