This is the only brand I use. It's very easy to use, keeps the heat in, and the cold air outside. You can also do it by yourself. I love this product. I love all 3M products!!
works well... stays up all winter
Year after year, this product is a workhorse! It keeps the cold out until I want to take it down in the spring. It cost more than off brands, but it is so worth it!!!!!!
The delivery was timely, it's a 3M product, but I haven't used it yet. I have high hopes that this will be the answer to my prayers.
Winter is coming get em now!!!!!
It works to help keep cold out removing takes some work
I have used 3M and other brands, and none compare to the 3M brand. The tip included in the box, using tape to find the last fold works really well.
THIS PRODUCT IS EASY TO INSTALL AND THERE WAS PLENTY OF IT BUT, IT ONLY LASTED A WEEK. IT JUST STARTED TO PEEL OFF. IT IS VERY THIN TO BE CALLED A THERMAL INSULATOR. ALSO, IT COLLECTED CONDENSATION BETWEEN THE PLASTIC AND THE GLASS WHICH RAN DOWN AND POOLED ON THE FLOOR. AFTER THAT HAPPENED IS WHEN THE PLASTIC SHEATH BEGAN TO SHRED APART. I WOULD NOT RECOMMEND THIS ITEM.
I went with this kit thinking it would be better than the cheap ones and it is not. tape does not stick well and plastic ripped a few times. i had to use gorilla tape to make it work and it looks bad. not the first time i have sealed a door. try a different kit.
The item pictured is 6.8ft x 19.5 ft, but the actual item sent is 6.8x9ft. Two totally different items.
