Frost King Available R930H Sponge Rubber Foam Tape 9/16-Inch, Black, 1/2" W,9/16" T

Good foam easy to install and works well

Product is dimensionally as described. I use a portable air conditioner in my garage, however there were gaps where the window sash rests on the exhaust plate. Moths were coming in at night and fluttering around my security cams causing unintended motion alarms.I've not had any fluttering intruders since dealing with this product.

Worked decently, had to remove and apply a different product this didnt do exactly as I needed.

I used to help insulate in and around the windows for my 2 portable A/C units - great adhesion to the windows, as they're vertical windows I was able to stick it under the sliding pane and it comfortable molded around the window kit, and it fit perfectly in front of the kit, between the interior sill.The insulation can easily be cut into small squares that fit in those little holes/nooks and cranny's as well, and it sticks really well! There was a small crack around the window kit I installed, and you could feel the air blowing strong - once I put this in that hole, bam! No air flow, and it keeps cool even with direct sunlight.

As expected
