Window Air Conditioner Foam Insulated Panel, 17-Inch High x 9-Inch Wide All Season Protection Window AC Side Panels Kit with Air Conditioner Top Seal Strip

I used these for winterizing my window air conditioner -- I put on an insulated cover on the outside and a separate one on the inside for extra protection. I then used these two foam panels on each side of the unit as extra protection.

This is like a foam board with adhesive. It does the job of keeping air from seeping in around your air condition, although it doesn't look clean and neat but that just could very well be the way I cut the product and the shape of my window.

We love this stuff! It has made quite a difference to our setup. It looks nice and is more insulated. I really like how nice the bedroom looks and how easy it was to install.

I don't like the tape they should provide a double sided tape to do the installation

This is NOT easy to assemble. It does not cut easily or evenly for that matter. The tape does not stick well and it feels cheap, especially for the price. Would not recommend! Wish I could return it.

This product was easy to install and does an incredible job of insulating the air conditioner. It covered all gaps in the window and was very easy to cut to size.

First time leaving a/c in window and this product helped to insulate around it!
