I used this foam insulation tape for my window AC unit and it worked really well. It was easy to cut and install, and it fit perfectly in the gaps around the unit. It definitely helped seal everything better, and I could feel less air coming in from outside. It also made a small difference with noise, which was a nice bonus. The foam feels durable and sticks well without peeling off. So far it’s holding up great. Overall, it’s a simple and effective solution if you need to seal gaps around a window AC. I’d buy it again.

This fowong air conditioner window seal works exactly as advertised. The 1" x 1" thickness is perfect for filling gaps around the AC unit and does a great job blocking hot air, dust, and drafts. It was easy to cut to size and install, and it stays in place securely. The material feels dense and durable, not cheap foam. I noticed an immediate improvement in keeping the cool air in and outside air out. If you need reliable weather stripping for your window AC, this is a great option. Highly recommend!

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.

Extremely squishy and has good adhesive. Used in my truck to seal the open airbox against the hood and direct hot air away from the intake filter. Works great and will be buying again in the future.

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.

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 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.
