3M Indoor 84 In. In. Oversized Window Insulation Kit 2149W-6 Pack of 6

instant savings, awesome product

3M is the best EVER...I order this plastic every single year to cover my non-insulated windows and instantly impressed how much it keeps the cold and heat from coming in my home....I just installed the plastic the other day and before I put it on my windows the temp was down to 58 degrees without any heat or air on in my home....instantly the first days after putting on the plastic my temp in home was 70 degrees and went down to 68 but so far not lower...try it....easy to put up...see through...and instantly be as impressed as I am twice a year...summer and winterRead full review

The best window film and tape available.

Clean the sill before you apply the tape and it will stick reliably. The film is folded so seamlessly that it appears short. Carefully read the instruction that recommends using two pieces on either side to separate. Read full review
