Yotache Open Cell Foam Air Conditioner Insulation Seal Strip 2"x1", Non-Adhesive Air Conditioning Weather Strip, 6.5 Feet Long

Great price worked well has great adhesive

Best insulation ever.

It does the job of sealing gaps and stops drafts and keeps out insects.

Worked well with my new AC from Amazon.

I love this foam! It’s sturdy and flexible, stays where I put it and is very dense so it makes a good seal

Good stuff

Perfect insulation for those shafts in the windowsill!

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.
