This was a great find. I feel extra protected from any critters getting through the side of my window. It looks nice too.

This is not easy to use, it is very cheap, and the wind will come in, so it will consume a lot of electricity. Dont buy it.

I have done a lot of diy AC unit insulation using duct tape and cutting up curtains and plugging up tiny holes. Not only did these foam pads do all of the work in about 10 seconds of prepping, they worked probably better. Better seal, better sound proofing, better insulation. Are these traits specific to this brand? Im not sure, I havent test many of these products, but this one did the trick, highly recommend if youre looking for a good way to block out sound, light, keep the bugs out, or whatever. It’s just so easy, and they were mighty large too, so I had plenty of extra to cut off as well.
