works ok so far for condensation
Got this to reduce condensation on windows in the winter. Works so far for 68 degrees F and 60-70% humidity inside and 30’s outside. Compared to the Duck Brands equivalent stuff, it’s more transparent/clear and has a more rigid rather than stretchy feel to it. Although the instructions don’t say so, you CAN shrink it to get rid of wrinkles with a hair dryer. Currently using this indoors rather than outdoors as it’s marketed – I figure that’s fine rather than doing the reverse.

Worked for me
I didnât buy this for a door but rather double windows that are larger than the window package 3M has. This product worked perfectly for the winter months! I didnât expect it to stay flat as itâs normal for the plastic to become one big bubble when the barometric pressure in the atmosphere rises, so I left some slack in it when applying it. I also did two lines all around the window of the adhesive tape that comes with this item. Also – I attached it to the wall outside of the window, not the window pane as I felt this was better coverage and less likely to leak. One thing that I think most every one can agree on – I wish the adhesive was stickier! Had it not been for the two rows of the tape then it definitely would have come undone.

This does work! Great for Rvâs
First off the only reason this product does not get 5 stars is because there is not enough tape included in the package.The product itself is 5stars. We put it on our large Rv window last winter and it worked so well that we bought more and did all our windows. If you have ever been in an Rv during cold winter months youâll understand how important this is. It allows natural light while keeping drafts away from the metal framed windows. Itâs easy to put up and if you get it up tight itâs not unsightly. In the video you can see how nice it looks and also youâll notice the black tape vs the white (included) tape. Also it cuts down the condensation (iykyk) greatly and ice formation on the glass panes. Save yourself a headache and buy extra tape before you start installing. We were lucky to have some on hand but boy I would have been super disappointed if we did not.

A great way to keep the warmth in on those cold New England days.
I’ve used this weatherproofing kit on our outer windows for at least the last 20-25 years. Our house was built in 1884 and breathes through the walls and windows each winter. This winterizing kit for windows makes a huge difference in our natural gas bill and the comfort of our house. It’s fairly easy to apply once you’ve read the directions. I buy an extra roll of tape along with the kit to make double rows of tape so that there is enough to hold it on tightly. I learned that lesson the first year I used it. Also, you really do need to clean the surface well before applying it to make sure it stays on during Noreasters! Once you’ve applied it, the blow dryer should get rid of any wrinkles. I use prepackaged alcohol prep wipes to get all the dirt and oils off the surface before applying the tape. It doesn’t cost much but I think of it as insurance to make sure it lasts through the winter. You should clean the outer glass panes before applying so you don’t have to look through dirty windows all winter. I absolutely love this product and wouldn’t go thru the winter without it.Linneaann

Patio door kit
Will not stay on your door if itâs exposed to weather and wind. Easy to put on but blew off.

keeps cold and heat out
With this changing environment I have been unable to let my screens be uncovered. I have a cat door that doesn’t fit in the custom sliding door and it has to be used with the screen door. Way too cold in the winter and this summer was too hot. So I put this over the screen door and it kept the temperature way better in both seasons.

Plastic is super thin and ripped! Buy Frost King Instead!
I have always used Frost King products to cover 4 sliding glass door for the last 5 years. This year I bought these 3M panels and 3 of the 4 ripped!! I had to buy Frost King again,

Easy to install and can’t tell it’s on after you use hair dryer to tighten it up. Will buy again.

One out of 2 packages was completely unusable because the plastic was fused together and although we’ve used these products for years without any problems, these ones keep coming off. The sticky tape condition was compromised. Have had to order more of the window kits (and pay significant shipping) but hope they arrive in better shape or next time we’ll try a different product or order from elsewhere.

This was the worst item I have ever purchased online. The box had been opened there was no tape in the box, and it certainly was not the item as described. It was a scrumpled up sheet of plastic that was even cut to size. Ib think someone just put a random piece of plastic in the box. Absolutely disgraceful.
