  • Perfect solution
Color: White Size: Fits up to 36" Wide Window
Super easy to install and looks very clean, like it’s part of the wall (I have white walls). It’s very well padded, made of durable nylon type fabric on one side and dense foam on the other. The sticky side was great and feels like it won’t budge. Great seal and easy to cut to fit my window. I love that I can keep it up year round too, 10/10 ... show more

  • Perfect and just what I wanted! 🌟
Color: White Size: Fits 36" - 40" Wide Window
I bought these Breeze Stop Surround Insulation Panels for a large 39 inch window 🪟 in an upstairs guest bedroom/office. Even though we will be using these panels for less than three months total this summer, I totally consider them worth the investment. Love them! 🌟 Because the window is so large, the extended air conditioner side panels did not completely reach the window frame on both sides upon installation. (We had purchased a new, small 5,000 btu unit and the side panels simply weren’t long enough for the size of the window.) We improvised with a few layers of clear heavy duty window sealing tape on the sides to tape up the openings. (Of note: The brand I bought from Amazon is SWRT 2”x 90FT 8 Mil Heavy Duty Transparent Window Weather Sealing Tape, No Residue - which I must say is a fabulous product! Thick, strong, durable and truly no residue upon removal.) Once taped up, the air conditioner was secure but needed something more. This is where Breeze Stop came in. The panels provide insulation and privacy. 👍 Upon receipt of the Breeze Stop Panels, I could see their thick grey foam and covering vinyl. The 40” size was sufficient for the window. I carefully measured and cut the panels to fit with scissors, ✂️ which wasn’t a problem. Note: If you have very old, dull scissors ✂️ do yourself a favor and buy some new sharp scissors! Just take your time and measure and cut correctly. The insulation side panels neatly fit into each side. I was able to use excess pieces to seal the bottom area, too. I then used the window sealing tape to tape around all the edges. I actually didn’t need to, as they were all securely wedged in, but I hate bugs 🪰🪲so wanted to seal it completely. 👍 It looks great! See my pictures. The foam insulation side panels are thick and insulating against outside noise. They also provide insulation for the window panels and keep the cool air in the room. It honestly wasn’t that hard to install! I plan on reusing these side panels next year if I can, or just buying another one next summer. The panels seem durable and well made. Living in the Northeast, we will be taking this air conditioner out come September and storing it for the winter. ❄️ So in summary, take your time, measure correctly and carefully, and have sharp scissors! Highly recommended! 🌟🌟🌟🌟🌟 ... show more

  • Breeze Stop Side Panels: Effective Insulation for Window AC Units in All Seasons
Color: White Size: Fits up to 36" Wide Window
The Breeze Stop Surround Insulation Side Panels are a practical solution designed to seal the gaps around window air conditioning units, improving both insulation and energy efficiency year-round. This product consists of two side panels (18" x 10") and a top panel (36" x 1.75") that are easy to cut and fit over the existing plastic panels of window units. The panels are made from insulating foam covered with white vinyl, which blends seamlessly with most interiors. Key Features: Effective Insulation for All Seasons: These panels help keep out cold drafts in winter and prevent heat from entering during the summer, addressing the common problem of air leakage around window AC units. By ensuring a tighter seal, they help reduce energy consumption, making your home more energy-efficient. Simple Installation: The panels are designed to be easily cut to fit various window sizes, accommodating windows up to 36 inches wide. Installation is straightforward, and they adhere well to the AC unit, creating a secure, sleek fit. Aesthetic Appeal: Unlike other makeshift solutions like towels or foam blocks, Breeze Stop panels offer a clean, built-in look that matches indoor walls. The vinyl surface is also easy to clean, making maintenance hassle-free. Durability and Performance: Made from 1-inch thick insulating foam, these panels are built to last and provide year-round insulation, helping maintain a stable indoor climate. Ideal Use: This product is especially beneficial for people who live in regions with extreme seasonal temperature changes, as it enhances both the cooling and heating efficiency of window AC units. Final Thoughts: The Breeze Stop Insulation Kit is a well-designed, cost-effective solution for anyone looking to improve their window air conditioning setup, whether in the sweltering heat of summer or the chilly drafts of winter. It is user-friendly, blends aesthetically with home decor, and provides long-lasting insulation. While a bit pricier than some DIY options, its durability and clean finish make it a worthwhile investment for energy savings and comfort. ... show more

  • No more draft
Color: White Size: Fits up to 36" Wide Window
Works great and was simple to apply. I read reviews and took advise to watch video first on how to apply. Did that and measured and cut to perfection. It looks so clean and stopped all the drafts. Great product.

  • Work perfectly!
Color: White Size: Fits up to 36" Wide Window
This is the one of those things that you buy just to check and see if it will work, then use it and immediately order more! I used to use duct tape to seal the ACs in the windows every summer and my husband hated it because it ripped off the paint on the trim, forcing him to touch it up every fall. Problem solved now! Not only that, but I’ve noticed a SIGNIFICANT improvement in preventing drafts because the padding is so thick and insulated! Keeps out tiny bugs that got in too! The instructions that were included were very easy to follow, though you really should take your time and do it carefully because if you over-cut the material, the whole thing is useless. So always overcut by a couple millimeters and you can always smush it in or trim it with a sharp utility knife. The adhesive is very strong, haven’t any issues with that. We have five AC units altogether, each one a different size, so I bought these because the size could be customized and they really do fit any type of unit. I honestly can’t praise these enough. So happy I tried them! ... show more

  • Works as expected, but prepare yourself
Color: White Size: Fits up to 36" Wide Window
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. ... show more

  • Only works for 36” window if your AC unit is at least 16.5” wide
Color: White Size: Fits up to 36" Wide Window
I have a 36” wide window and a 16” inch wide air conditioner and the side panels left a gap of slightly larger than 1/2”. The top panel left a similar gap of just about 1/2” on one side. This meant I had to stuff some foam on the one side to fill the gap to achieve the proper insulation but now it doesn’t look nice and uniform - first world problems but irritating given these are not cheap for what they are (foam panels covered with soft vinyl). If your AC is wider than 16” or your window is less than 36” you should be okay. If not, grab the 36-40” version to get full coverage. **my photos are from before I stuffed extra foam to the one side, I had also not used the tape to affix the panels to the AC unit at this point so that I had flexibility. I also offset the top piece so the gap was opposite from the side panel gap, so that I could use the top panel on the one side to help conceal/hold back the extra foam. The tape seems to hold well but these will most likely be a one season use item unless you’re extra careful uninstalling/storing them and or don’t care about taping them back on in the future. ... show more

  • Excellent, but with a caution.
Color: White Size: Fits up to 36" Wide Window
It was easy to use, and fit really well. It blocked out all air and outside temps. One problem though. Consider it a permanent installation. I can't remove it from our AC.
