Seal the gaps. Cut the drafts. Give your window AC a clean, built-in look.

If you have a window air conditioner, you've probably lived with it — the cold air that seeps in around the sides in winter, the gaps that let bugs and dust through, and the cheap plastic accordion panels that make the whole setup look unfinished. BreezeStop fixes all of that in under 10 minutes.

The Surround Insulation Kit wraps around your window AC unit with two insulating side panels and a top panel, sealing the gaps that your AC's built-in plastic panels were never designed to handle. The foam-core, vinyl-covered panels blend seamlessly with your interior walls — no more eyesore, no more drafts.

Whether you're battening down for winter or trying to get more out of your AC in summer, BreezeStop pays for itself fast. A sealed window means your AC runs more efficiently, your furnace works less, and your home stays comfortable year-round.

What's Included:

  • 2 side panels (20" x 10")
  • 1 top panel (40" x 1.75")
  • All panels are foam-core insulation wrapped in white vinyl

Fits windows Between 36" and 40". 

Easy to install — trims to fit with scissors or a box cutter. No tools, no hardware, no contractor needed.

Frequently Asked Questions

Will this fit my AC unit? The BreezeStop Surround Kit fits any window AC installation in a window Between 36" and 40". The panels are designed to fit over your existing plastic accordion side panels — no need to remove anything first. 

Does it work in winter too? Absolutely — in fact, many customers buy BreezeStop specifically for winter. The gaps around a window AC unit are a major source of cold air infiltration. BreezeStop seals those gaps and adds an insulating layer to reduce heat loss significantly.

Can I cut it to fit my window? Yes. The panels trim easily with scissors or a box cutter, so you can customize the fit to your exact window dimensions.

What color are the panels? The panels are white vinyl, designed to blend with standard interior walls. Some customers paint them to match their wall color — standard latex interior paint adheres well to the vinyl surface.

Does it work with all AC brands? Yes. BreezeStop is brand-agnostic and works with most traditional window units.

Before you buy

Questions, answered

Will it fit my AC unit?
It fits any traditional window AC in a window up to 36" wide. The panels are trimmed to size during install, so you get an exact fit. Wider window? There's a large size available too.
Does the adhesive damage my wall or window?
No. The adhesive flaps attach to the AC unit itself - not your wall, trim, or window frame. Nothing sticky touches your home, and the panels peel off cleanly.
Do I need tools to install it?
Just scissors or a utility knife to trim the panels to fit. No drilling, no hardware, no contractor. Most people are done in a few minutes.
Can I take it off and reuse it?
Yes. It's removable and reusable, so you can take it down when you pull the unit for the season and put it back up next year.
What exactly comes in the kit?
Two side panels (18"x10"), one top panel (36"x1.75"), and pre-attached adhesive flaps. Everything you need to seal a standard window AC.
