Yotache Window Air Conditioner Foam Insulation Strip 2 Pcs 1 X 1 Inch, No Glue Thick Foam Weather Seal Strip with High Resilience, Total 13 Feet Long

Very dense foam and well priced and totally accurate description. I am using this foam behind the curtain rails to block light going up to the ceiling behind the curtains since the sun rises at 5am in the summer!!!! I will have to add double sided tape to it but it is still a great item, as described, just wish it came with tape.

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.

This isn’t flimsy. It will definitely help fill any gaps in the window

Used thi to seal around and under my AC window unit. Long enough to go all around and a little, 1ft to put underneath AC to prevent vibration. Thought it was to wide, but was just right to seal all around and easy to install.
