Window Air Conditioner Foam Insulation Panels

These foam insulation panels worked out great for my window AC. They were very easy to cut and install, and they fit snugly on both sides of the unit. The material feels thick and durable, and it definitely helps block out drafts and hot air from the outside. I noticed right away that my room stayed cooler and the AC didn’t have to work as hard. It also helps reduce noise and gives the window a cleaner, more finished look compared to the flimsy accordion panels that come with most units. Overall, this is a simple but very effective upgrade for any window air conditioner. Great quality and great value.

These side panels are exactly what I needed and they work! I love that you can cut them to fit perfectly!

Thickness is good and easy to cut to fit your window. Price is excellent for what you get. I ended up buying another one in white for another window ac, but light comes through it easily. I might buy it a third time but in black. I use the parts that I cut off as window insulation during the winter, so I got more value out this then I expected.

This was the perfect replacement for the window unit in our storage building. Easy to assemble and place.

Does the job, but worry about durability. Will the foam inserts withstand heavy rain or wind? Foam clearly is not waterproof, so not sure. Reasonably easy to install, just be patient. Final fitting and trimming occurs with AC and window in “closed” position, so have to manipulate and trim foam with access from only one side.

Work awesome

Nicely covers the ugly side panels that are found on most window air conditioners. Gives a cleaner look. Easy to trim and install. Reduced drafts. Adhered well.

Helps the look and keeps the cold out

You still need your side panel frames for these to work - this is not a full side panel replacement if you misplaced them or have broken the plastic exterior to your AC panels. Foam is good quality, however pictures are misleading.
