Surround Insulation Side Panels White for Window AC Unit Indoor Air Conditioner Cover for Winter and Summer

Fits my AC perfectly and really helps block drafts from coming in such that I can leave my AC in the window all winter.

As a preface: I consider myself a veteran of the "custom DIY" foam struggle. My previous attempt involved hand-cutting poster board and foam in 90-degree heat while solo-installing an 80lb, 12,000 BTU beast. Because that rushed job was subpar, my New England winter was full of unacceptable drafts and a humidifier that couldn't keep up. Since I refuse to lug that 80lb unit to a basement storage in another building every year, I needed a real solution. This kit was it. It took me about 1.5 hours. Be warned: the materials are soft, squishy foam with vinyl backing. It is not "fun" to cut, especially trimming down millimeters of soft material because you don't like how it looks on the test fit. For most people, you'll likely be restricted to scissors and/or a utility knife. - I recommend ditching the scissors.. Scissors will compress the foam before actually cutting, leading to jagged edges. Use a utility knife with multiple light passes. Let the blade do the work, or you’ll bunch the foam and end up with a mess (or a bandage). - I recommend cutting 1/8" (inch) wider/taller than your actual measurement. I tried 2/8" at first, and it looked like a crumpled accordion in the test fit. 1/8" inch provides a perfect, snug "wedge" fit. - I actually found the adhesive unnecessary; the pieces fit so snugly that they stayed in place on their own. The quality is good for what it is. The thickness is legitimately sufficient to keep the frigid New England air outside where it belongs. It costs about the same as my failed "custom" setup but looks significantly less "unsightly." Value is definitely here. Bonus: My window frame is 32.5", and AC is 24" wide. The 36" kit yielded me enough extra materials to insulate the bottom of the AC as well. Godspeed with your installations. May your cuts be straighter than mine.

Manuel facile à suivre. Excellente isolation et vraiment esthétique.

Really great! I could always feel hot air leaking in through the sides of our air conditioners. Our apartment has basically no insulation, so it’s always a struggle to keep it cold in the summer and warm in the winter. It is thick enough to keep the drafts out. Was very easy to install. It also makes the ugly air conditioner look a little better. It was easy to cut to the size needed, stuck to the window well and did not take any paint off when removed for the season. It held up well and I expect that we will be able to use it again next summer with some double sided tape easily added.

A little pricey for what it is but does the job. It does have a clean look and prevents draft.
