EBFRML: I used this to make a seal around the lid of my ice chest and it worked excellent. It has stayed in place and the high density foam holds up.

Dynaflowhum: I used this product for a window A/C unit. Makes a good gap seal for an A/C installation. Easy to form into any small gaps and does stay in place with its adhesive backing. Made the installation of a window A/C unit quick and easy.

pepper: it works to seal around an AC unit.
but to seal a window or door?
it will not compress without serious pressure.
but if you gap is 1/2" it might compress "IF" you apply a LOT of pressure - them lock it in place
on the gap between a window and ac unit it does well as there are minor differences/voids to fill that are
about 1/16 of an inch that were filled/blocked off for insects. [be sure to install it warm] as it sticks better
our window has a vinyl frame that it stuck to pretty well.
the foam is high density, So it goes in best when warm. [a bit more than room temp (72f) with the foam warmed to almost 80f.
it is easy to see it will do well in our application, but on a door or window that might be opened more that twice (?)

SMW: This is a nice dense foam seal, which looks robust and simple to apply. There's a decent amount on the roll, and it represents good value for money. Recommended.

Jalapeno: The tape itself looks good, but the glue / adhesive is not very strong. This could be an advantage in some situations (e.g., where you have to adjust or remove it, or it's held in with friction), but not recommended for situations where you need something to really stick. I'd also say it's only about 3/8 of an inch thick -- not a half inch.

BrooksBrooks: I bought this self-adhesive foam tape to block the draft under the door. I applied it to a clean not greasy surface (painted wooden door) as directed.
At first it worked perfectly, but after a few days it fell off even though it was not in contact with anything. There is a gap between the floor and the bottom of the door where I attached the tape, so the tape did not grab on to the floor or anything else. I had to use a glue to put it back in place.
Since then I have used it on several other surfaces like glass, wooden furniture and it fell off again after a few days without being touched by anyone or anything.

Overall, it is a good tape, but do not count on it sticking to things. You will probably need a glue.

Tlmsrr: This tape was interesting to me when I first got it. It was way thicker in width than I thought (but that was own fault as I don't know measurements). I had to unwind atleast half of this tape and I just cut down the center to fix this problem. The tape was sticky as I did this, but it had to be done (for me). Then I applied it to only one side of my doorway and the top (because when I applied it to both sides of doorway, it would not shut). The tape stuck to the side and top but some spots it didn't look like it was sticking too well. So I pushed it again real hard. After I was done, there were still some parts not sticking just right. However, over the next 2 days, it settled in and now is stuck to the side and top of my doorway perfectly! It just needed time (and at first for me to push on it a couple of times after first applying it). Trust me, it works, if you work with it at first.

Also, it really helped with dampening the sounds from outside my room, that I hear.

*And do not worry if you touch the sticky side of this tape ALOT before applying. Because that's what I did, and it still stuck fine in the end result.

**Just make sure, you clean the area you...
