fowong Low Density AC Foam Weather Stripping -1/2" W X 1/2" T, Window Seal Strip High Resilience, Door Insulation Tape, 2 Rolls X 6.5 Ft Each

The foam seal on my standalone generator decomposed after many years and the seal was not available from the manufacturer. So I took the dimensions of my original foam seal and this was close enough in size and is heat resistant. It worked very well since I had to make this into a circle.Many reviews say it's very difficult to remove the adhesive backing paper. But, per an earlier review, someone said to just squeeze/scrunch the foam part of the foam gasket at the bottom to remove the backing paper. So when the product came in I did exactly that and the backing paper very easily peeled off and left the adhesive on the foam gasket. After removing the backing paper it was very easy to form a circle with the foam seal and I placed it on my standalone generator.Consider this, at least 2 reviews, saying the backing paper will easily come off if you squeeze/scrunch the bottom of the foam before trying to remove the backing paper off the adhesive on the top of the foam seal.

i used this to close off the space around the portable a/c window unit.. it sticks very good. and peels of excellent when winter comes around and time to store the a/c unit. nice and thick. draft protection. seal is great flexibility and ease of installation and removal.

Used this to help keep my room cool. It also blocks sound. My neighbors are loud all the time and now I barely hear them. Adhesive is strong, once it’s on there it’s on good. If you try to remove it you might notice some adhesive gets stuck to the surface. Overall it works great, make sure you get the right size for what you’re using it for.

The foam is very soft and flexible. The adhesive is very tacky and bonds extremely well. Sealed up my attic door opening and eliminated heat leaking around the perimeter of the stair door.

I recently bought the Fowong Air Conditioner Window Seal, and it’s exactly what I needed to seal up my AC unit. The foam density is spot-on—thick enough to fit snugly around the edges and really seal up any gaps, ensuring no air leaks. The foam provided by the manufacturer was a corner cut. I'm so glad this company thought of a solution for all of us with portable air conditioners.One of the features I really appreciate is the adhesive on one side. It has just the right amount of stickiness, making it easy to reposition if you don’t get it right on the first try. Plus, the roll is long enough for a second attempt if needed, and it’s also great for fine-tuning any leftover openings around the window where the air conditioning exhaust fan goes.Overall, this product made the job of sealing my AC unit quick and efficient. I’m very satisfied with how well it worked, and I would definitely recommend it to anyone looking to secure their AC setup.

Finally installed my window AC this week. Last year I remember how I had some areas that didn't seal up well as the seals I used were not thick enough. This product solved my issues and was simple to install with a pair of scissors.

The adhesive on the strip is super sticky. I began imagining the end of the season and how much effort it would take to remove the strip and adhesive. It seems that adhering this insulation strip to the AC flange or the AC window panel flange should be the recommended instruction instead of to the window sash. Because it is so soft and pliable, no gaps remained AC panel and sash. Well worth the price. BTW, do not store it unused in a warm place as the paper backing is likely to be difficult to peel away from the strip. Easy to measure, cut and adhere, and well worth the price.

Although it is a good product, it does not compress as easily as it shows in their videos and description. It is a nice quality, but if it compressed a little easier it would be better.
