yotache Window Air Conditioner Foam Insulating Strip 1 X 1 Inch, No Glue Thick Foam Weather Seal Tape with High Resilience, 6.5 Feet Long, 2 Pcs

This foam is durable and tough, but very flexible and can be compressed a lot or cut into smaller pieces for tight spaces. And it can be re-used year after year. Works very well for blocking gaps around window AC. I use 1-inch foam between window sashes, and 2-inch foam around the AC and its side curtains.

Good quality, density and pricing. Doest what it's supposed to do

Nice thick strips. Easy to install. Imagine this will last a few years if stored properly.

I don't often write reviews, but I have to say that hands down, this is the most high quality insulation foam I've come across on Amazon. I purchased it to use in place of the cheap, thin, smashed up ridiculous crap that Amazon provides with their Midea window a/c units. This particular foam is very soft, thick, and bounces back as an insulation foam should. It has a smooth satin finish on one side. The other side is more of an open foam. I purchased the 2" foam moments ago to finish off the insulation of the window unit. Great product!

It’s the recommended stuff to insulate your window ac that Amazon advertises that replaces the inadequate amount and insufficiently poor performing stuff that is typically included with your new AC. Unfortunately it’s too squishy and even doubled up it will wiggle and escape where you place it. I think it’s a better insulator, but without anything adhesive on it and it’s inability to stack itself and stay put I was left with the more obvious issue of uneven black snake like material re-emerging quite visibly and looking well “Homer Simpson-esque”. DISCLAIMER: Many “projects” I attempt look like this in the end, so take this review with that salty stuff they give you for a colonoscopy (Go Class of May 28th ‘22) and don’t take this review too harshly. It’s just my lack of skill and it’s inability to adhere to anything as it’s missing said adhesive side.
