LBG Products Window Air Conditioner Foam Insulation Panels,AC Side Insulating Panel Kit,2 Pack,Black, 17in High x 9in Wide x 7/8in Thick

Works great

Fits the window perfectly

I have an AC in my bedroom window and the sides that come with it are in fine shape but let light in, this solved the problem in about 1 minute. I didnt use the sticking part, just cut a little long and stuffed it in place. Im stupidly happy about this, haha!

This is for a large air condition and I have a small one did not fit

These add extra protection from the elements that the extensions that come with a window don’t also helps dampen noise from outside. I’d buy them again.
