good enough for the job

By themanthatuseshisbrain

Comments about ACE HARDWARE 3M® Indoor Window Kit (2149W6):

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.

plastic film NOT 6.7' tall... not even 4'! :(

By shubes61

from Harrison, NJ, United States

Comments about ACE HARDWARE 3M® Indoor Window Kit (2149W6):

i bought the indoor window insulation kit for one XL window, with the plan to cover a 12' by 5' living room window... the film was more than wide enough... but it was a good foot short of covering the window top to bottom! totally frustrating and totally mislabeled on the box! we're trying to piece it together now... but the film is NOT the size it's supposed to be.

    Been using 3M Indoor Window Shrink Film for many years. It is the best kit out there. Included two-sided tape stays put and the plastic is good quality and crystal-clear.

        Comments about ACE HARDWARE 3M® Indoor Window Kit (2149W6):

        To seal indoor windows air tight with no drafts apply in the late fall and take off in early spring. Follow the directions and the tape will hold tight, the film will pull taught and be very clear. This product works better than all the others I have tried at Walmart, Home Depot, Lowes etc.
        The kit is far better than the competition. Buy it at ACE every year after trying the others. You will get excellent results.
