Breeze Stop Surround Insulation for Window AC Units (Fits up to 36" wide window)

The gaps around your window AC are costing you money. BreezeStop seals them.

The accordion plastic panels your unit came with aren't real insulation — they flex in wind and let cold air straight through. BreezeStop fits directly over them, sealing every gap and giving the whole installation a clean, finished look.

What's in the box:

• 2 side panels (18"×10") — slip over your existing accordion sides
• 1 top panel (36"×1.75") — seals the gap above the unit most people ignore
• Adhesive flaps — attach to the unit, not your wall or window frame

What it does:

• Stops cold drafts in winter
• Blocks hot air infiltration in summer
• Reduces outside noise
• Turns an eyesore into a clean, built-in look

What it takes to install:

• Scissors or a utility knife to trim to fit
• No tools, no hardware, no contractor

Works with: Any window AC brand. Fits windows up to 36" wide.
