    Customer Reviews
    3M™ Indoor Window Insulator Kit, XL Window is rated 2.9 out of 5 by 9.
    Rated 4 out of 5 by from I assure you there another layer When opening the package I experienced the same concern as the 1 star review. I thought I was ripped off and the plastic wasn't 6'8" but after 30 minutes of messing with the plastic I managed to separate the layer and unfold it into the proper height. After that everything was fine, but the it was really hard to find the seem and separate that layer..

    Rated 3 out of 5 by from Tape has changed! For 30 years I have been spending in the ballpark of $100 every heating season for this film and tape and never been sorry (although I have wished I had enough tape as it is SO expensive in the separate rolls). This spring I find that every single window plastic has released from the window frame. EVERY SINGLE ONE. This can only be some change in the tape, because nothing else is different. I don't know whether to be angry or grateful, because I am finally ready to bite the bullet and replace all the storm windows.

    Rated 1 out of 5 by from Film too short I work at a hardware store in town and sold the window kit to a customer for her windows. She brought it back saying it was to short, we examined the product and it was to short. It shows that it should be 6'8" but was less than 4'. We opened another package of the product to check it. It was also too short.

    Rated 1 out of 5 by from DO NOT BUY... FIlm is TOO short The film that came in both of my packages is 3 foot 8 inches and NOT the 7 foot that it promises. I opened two different packages and the same thing! THis is frustrating and I have had to go back to different stores numerous times to buy, rebuy and return. DO NOT BUY THIS MISLEADING PRODUCT

    Rated 1 out of 5 by from Wrong Size I bought this expecting 6 ft 8 in x 19.5 ft. The product inside is not even 4 ft wide...although it is the 19.5 ft long. Hopefully stripping the window will seal properly...Bought Nov 2017

    Rated 5 out of 5 by from Works Very Well and Easy Installation I have used this product three times in three years. It is perfect for my very wide 4-panel patio doors. I agree it would be nice if the box mentioned that it is big enough for this purpose. The reviewer who thought the product was not sized as promise has my sympathy. The film is very thin and it can be deceiving when unfolding it. That is why the company include a little sheet with a suggestion for the best way to unfold the final flaps. Works perfectly. I suspect he or she was not able to discern the need for one more unfolding. Overall, an excellent product.

    Rated 5 out of 5 by from good enough for the job for the ones who think its too short, or not as wide, which ever your calculation is, once you get it unrolled and cut, unfolded, you still have to pull the plastic apart. it doesn't look like it comes apart but it does. use your dry fingers on an edge and keep "rubbing" between your thumb and index finger. eventually it will separate and be the thickness of standard kitchen plastic wrap you use for covering dishes.

    Rated 5 out of 5 by from Labeling is wrong We were looking for a plastic covering for a large patio door that was 12' wide. When looking at the product packaging it says it's for extra large windows with no mention of patio door applications. After looking at the specifications on the box and comparing it to a patio door product it was obvious the sheet was the same size as the patio door plastic. The box should say on it that it will work for an XL window OR patio door.
