Customer Reviews for 3M 84 in. x 112 in. Indoor Patio Door Window Insulator Kit

I've been using this for years, but this year the paper won't release from the tape making the product unusable. I see many others have had the same issue. Where is quality control?

The double stick tape does not stick well, like it use too. It’s to bad, because this has always been a great product and I s used it for over 20 years.

what a piece of junk. I've bought this kit for years and know how to apply it, this year the tape is horrible...I just threw out the kit and going to the store to buy a different brand....really 3M I thought more of your product but this is terrible...bye bye...not only me but whoever I could tell about you kit...it will be a negative ...come on the tape is terrible..and your 3M...

I have always had good luck with the indoor patio window insulating kit, and that is what I purchased again this year. After getting everything prepped, I started to attach the tape and realized after about 1/3 done, the paper liner wouldn't peel off! After searching the house (I'm in a rural area and don't have a store within 25 miles) luckily I found enough to complete the project. The film was fine. Disappointed.

I have used 3M window insulator kit for patio doors for years. Inside & outside & they worked great. One year I couldn't find it at m y store so had to use a different brand. Which was poor. Then last year I bought 3M somewhere & the tape was awful. It wouldn't work so I searched the house & found some old rolls of tape that were left from other years. They worked. I talked to someone at 3M & he assured me they were going to improve it for this year. So, I bought the 3M again & the tape is awful. Paper won't come off on either side. I got it off for about 6 inches then the paper ripped & can't peel it. I am so disappointed. Going to have to see what else is available. They need to improve their product or go back to the old tape which worked well

The poor rating I gave was in order to give feedback. I would have given a negative rating if it were available. The film was fine but the two sided tape was defective. It would not separate. Total piece of junk. Worthless. I asked local HD for credit for the tape. They declined. Never shop HD again.

I bought this one day ago. Paper will not release from tape. Plastic is super thin and does not shrink like it used to. Last year I had left over plastic and tape from the year before. From reading reviews I see the problem started last year. I’ve been using this product for over 10 years ,and always told people how superior it was to the competition. Sad to see a company that made a great product ,get so cheap just to save some money. Went and bought Duck max strength and tape and plastic is how 3m’s used to be. Plastic is not quite as crystal clear,but is far superior to 3m’s junk.

I have used this product for years and will only use the 3M Window Insullation kits. It is completely clear and most of all cuts down incredibly on my drafty old very large windows. I highly recommend this product. Cheaper ones are difficult to mount--pull apart in your hands. 3M Indoor Patio Door is best for 2 sets of large double windows and a custom made door...well worth the money.

After 15 minutes of trying to start a corner to peel off the paper liner, the paper tore and left a film on the tape so it isn’t sticky. There is no way to get it off and there is not enough tape redo. So frustrated with this product and will never purchase again.

Excellent product which completely stopped leaks.

The double sided tape has definitely changed it’s quality since last year. I have bought this previously and the tape has been easy to remove. This time the tape would not come off and it ripped leaving the paper side to try and pick off. Would NOT recommend

The tape doesn’t work anymore! It tears like a bad sticker every inch or two. Very frustrating. I returned all the boxes.

Could not remove the backing from the double sided tape provided without tearing it

I have used 3m tape for years but the tape in this package I bought today is defective. It was impossible to peel the paper backing off. I had to peel it off and start over with a separate roll of 3m tape I bought last year.

I was very annoyed with the product this time. The tape in both boxes did not release from the liner. I have contacted 3M. They have no replacement tape. They will send me a refund which is great but I don't really want more film, just more tape. But at least they are standing by their product.

[This review was collected as part of a promotion.] We had a cold draft on our patio door and it made our kitchen drafty in that area during the winter months. This easily installed kit made all the difference. It both blocked the draft and still allowed the light to come through. This is a product I will definitely use every year from not on.

I keep coming back because it really helps to keep the cold out. Easy setup and use.

[This review was collected as part of a promotion.] This is great for extra protection from winter drifts or if you have older windows. Helps keep warm air in. It is easy to install.

[This review was collected as part of a promotion.] Completely fixed the leaky window. Received for free.

Simple to install done the job

Somewhat difficult to install, but worth the effort. It does help a great deal in limiting cold air movement from older windows.

[This review was collected as part of a promotion.] I received a sample of the 3M Window Insulator Kit. This review is based solely on my experience. The film was relatively easy to apply and there was a good seal. It was no air movement through the window after the film was applied so I am expecting to see a decrease in my utility bill for heating. The film seemed sturdy and did not rip during the application.

Easy to install works great
