It's good squishy foam for sealing air gaps in windows and stuff

It's foam. I use it to close the gap on the top of the open windows when I put the a/c in. Works good for a few times. Then I gotta buy more. Does the job. I buy the 4 inch so I can squeeze it in there and get a good seal.

Get some tape with it

We live in a trailer with single pane windows this is a must have keeps the cold air in the bugs out and enough cushion for the flimsy windows in a trailer I buy it every year I could reuse it but I would have to keep up with itWhy did you pick this product vs others?:We also put them in the heat vents because the central air no longer works it helps keep Little critters out

This foam makes it so easy to fill in the gaps around my window, air conditioner units! It’s a great way to keep the cold air in and keep the hot air out!

Good if you need thicker insulation

Thick, heavy duty foam but it's too short for $5. I had to buy 2. You could buy thinner foam for most uses.

just as described

Just what I needed. It had been hot for a few days and these foams were sold out locally so I went to Amazon and got them right away. Easy to cut to fit perfectly where you need them.

Get this larger one

Worked great for me. I used some of it for cracks after cutting that piece in 1/2. Easy to do, so get thus larger one if not sure if size.

Ease of use

Came in very handy with my purchase of the Amazon LuckIn No Drill Window AC Support Bracket sold here on Amazon. Sealed up the bottom of my air conditioner no problem.
