Easy to install with just scissors and a hair dryer, it fits up to 10 standard windows with crystal-clear visibility and removes cleanly after the season. ## Description During the cold weather months, windows become a prime spot for energy loss. Duck Brand MAX Strength Brand Rolled Window Insulation Kits feature a puncture-resistant rolled film that is two times thicker than standard window kits to create an added barrier between the outdoor air and your home's inside. These heavy-duty window insulation kits help to block drafts that lead to high heating costs and are great for high-traffic or pet-friendly households. Our window kit film comes in an easy-to-use roll of shrink film, which means no measuring needed — simply cut the extra film off once applied. Plus, they are made with crystal clear shrink film for good visibility and are easy to install and remove. For best results, use on clean and dry surfaces, such as painted or finished wood, aluminum or vinyl. Review: This will help! - I found this window kit very helpful during this cold winter. Most of my storm windows are old and using this kit enabled me to seal these windows and reduce heat loss. The tape is very effective and easy to apply and I also found the plastic sheeting easy to handle. The plastic is very clear and allows good outside visibility. I have even used an old window seal kit and found both the tape and the plastic sheeting entirely unaltered after 3 years. I heartily recommend this inexpensive way to both keep more heat in your house and also eliminate drafts from old windows. Review: Works great - I had no issues what so ever putting this window insulation kit up! It was very simple as long as you follow the directions. The hair dryer made it air tight and took all the wrinkles out. It has helped so much to keep the cold air out. I’m hoping in the summer it helps keep the hot air out too! It fits my windows perfectly. It was one of the best prices I could find. It’s not cheap material and it has been up for over a month with no tape issues. ## Features - Save on energy costs during cold weather months.

The window film prevents and blocks drafts; however, we cannot guarantee it will block toxic fumes. **Q: Does this reduce noise outside?** A: Thank you for your question! The film blocks drafts from any air leaks around your window, which may help slightly with noise. **Q: Can this product be used to seal a wall air conditioner?** A: Maaaaaybe??? While it IS thicker, the corners will probably cut through. I think they make specific ones for air conditioners, though. **Q: También ayuda a aislar el ruido de la calle?** A: claro que no ## Customer Reviews ### ⭐⭐⭐⭐⭐ This will help! *by B***T on February 14, 2026* I found this window kit very helpful during this cold winter.
