fowong Air Conditioner Window Seal 1 Inch X 1 Inch, Thick AC Weather Stripping High Resilience Foam Sealing Tape Adhesive AC Window Seal Kit 6.5ft Long (6.5ft x 2 Rolls, Black)

It’s probably really strange to be as enthusiastic about window sealing as I am, but this product is great. My portable AC window panel has two extensions but they’re markedly smaller than the main panel. I used this thick and squishy sealing around the perimeter of the panel, and it worked amazing. The adhesive is really sticky and resilient but in some areas, all I needed to do was squish between the sill and the panels. The backing can be hard to remove but once you get the squish technique down, it goes quickly. Make sure to cut it to length with the backing on or your scissors may stick. I wish it came in white. That’s my only complaint. My panels and window sills are white.

This quality weather stripping tape is exactly what I needed to seal the gaps around my mother's window adapter panel for her air conditioner, and it's worked efficiently! She used to feel air coming from the window panel, But after sealing the panel with this seal foam tape, it resolved all problems she was facing regarding air, or dust debris.

This foam tape is very good quality, very sticky and easy to peel the lining, well, if there is any, the 2nd time I purchased this item the lining was gone for 3/4 of one of the rolls, it was all stuck together and when I unraveled it the foam was ripped off a little bit. the box it came in was very cheap and flimsy.

Came in handy for my window! Easy to use, came in great packaging. And I have extra which is great! It’s very thick!

Exactly what I was looking for!

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.

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.

The paper that covers the sticky part overhangs the end of the roll. Once you cut the first piece, it’s extremely difficult to peel the paper off of the next piece. Frustrating.
