During the cold weather months, windows become a prime spot for energy loss. Duck 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.

    • The tape doesn't always stick well. One person can do the install.
Size: Standard Window - 5 Pack
The double-sided tape included sometimes sticks to the wall or window frame, and other times it does not. I suspect this is because of incompatibility with some types of paint. I ended up using clear box packing tape to secure the edges of the plastic to the wall or window frames. This is behind the drapes, so out of sight. The shrinking works fine and make the plastic almost perfectly clear to look through. There is a film that is sometimes visible. I'm not sure if this is from packing powder used to make sure the plastic doesn't stick to itself or what, but it is sometimes visible based on the angle of the sunlight coming through the window. The box states, enough to cover up to 5 windows. This is true, but to do 5 windows, they will need to be fairly small. The funny part is that they are clear enough where flies and other insects run into the plastic as they fly towards the window light. The plastic is stretched tight, so they bounce off it and a drum sound is heard. I have two windows opposite one of my rooms, and the flies will go back and forth between them, making the drum sound each time they hit the plastic. This isn't a problem, the fly swatter comes out, and they are swatted. I put this here so if you decide to purchase and install this kit, you won't think you're going nuts when you hear this strange drum sound from time to time. My home is an old modified mobile home into a permeant residential house. Being so old, it has single pane glass. I'm hoping this kit will help reduce the winter heating costs. We have a few low 40 days/nights so far this year, and the kit seemed to work pretty well. The lowest the house has gotten to was 69 degrees on a 42 degree night. Other than the back door (large window in it) and a 3x4 window in the mudd room, all windows in the house have the kit installed. It took two kits to do 3 bedroom windows, 2 mud room windows, 1 dining room windows, and 1 living room window. I only gave a 4 star because of the tape issue. The plastic itself is easy to use, and shrink. ... show more

    • Easy Installation, high quality
Size: XL Window/Patio - 2 Pack
Easy to install, works as it should. We live in and older home, we could probably use new windows, but in today's economy- who can afford that? We've used other brands in the past years, but this one has really made a difference in holding in the heat. Installation is easy peasey!

    • Take your time installing
Size: Standard Window - 10 Pack
Amazing. I put it around my window frames due to the way it is. It was a simple install but a little tedious but once you shrink the plastic, it looks great. I live in an old uninsulated apartment so anything helps. I did this on just the living room windows and already noticed a difference of warmth the first day. Must buy. The tape is very sticky. The plastic wasn’t thin or easy to tear. Simple to cut since it’s folded. ... show more

    • Does well at insulating but struggles to stick on textured drywall.
Size: Standard Window - 5 Pack
This stuff does a surprisingly good job of creating a barrier from freezing temps outside. I went from curtains covering the entirety of the window and it feeling like there was an air conditioner blowing out the sides, to being warm and toasty inside even with the curtains open. BUT I'll be ripping it all out again in the spring since it's nearly impossible to make it look clear and nice like in the pictures. A hair dryer will shrink it, but if you shrink it enough to get all the creases out then there's enough tension on it that the double sided tape WONT STICK to my textured drywall interior very well. And yes I cleaned and dried the wall before hand. The tape sticks to the film well enough, that bond feels chemically fused almost, but the tape wont stick to the wall unless you leave a bit of slack, and wrinkles, in the film. ... show more

    • Amazing product will save me hundreds in heating costs!! Try this!!

Review Image by Mamazon Mamazon
The media could not be loaded. Great deal on this insulation kit. We live in a VERY cold part of the country and I did not even know these DIY insulation kits existed! Tried it out with one bedroom window that allows a lot of winter cold through and voila!! The instructions were perfectly clear and easy to understand and the product easy to install. Just cut to size of window, stick plastic to adhesive and use a hairdryer to make the plastic snug, similar to shrink wrapping (the LOW heat setting slowly shrinks the plastic to fit your window snug and keep the cold from coming through. This is ingenious!! The package is ample and provides enough plastic cover and adhesive for several windows. Duck is a trusted brand and this product is no different than their other stellar tape products. Having absolutely no experience or idea what I was doing, I successfully shrink-wrapped-winterized my window in twenty minutes or less. I will never be without this product to insulate my home for the winter. In one cold night it kept my kiddo’s room at least ten degrees warmer with only one of two windows successfully insulated and no form of heat. Frankly I am amazed!! If you’re not handy, don’t worry. You can do this and with the frigid cold coming, You need this!! This pack was less than twenty bucks and will no doubt make the difference of hundreds of dollars in winter utility/heating bills! ... show more
