Frost King AC41WA AC Foam Weather Seal, Heavy Duty 1-1/2" W, 1/2" T, 40" L, White

Just make sure the surface you use it on is clean and dirt and grease removed. I used alcohol and did it twice to make sure it would stay adhered. It’s nice to be able to seal a drafty spot, or around your air conditioner.

We needed to buy two because our ac was a bit larger than these were intended for! It fits really good and you can’t even see it! Has completely cut out any bugs which we had a huge issue with last year! Totally worth it!

The product is flexible and formable. Compared to the black product I ordered similar quality. Though I prefer the more robust black option.For the money the sponge like grayish product is better. It’s longer. Flexible and moldable. Better price for longer more versatile option.Though this is durable for three years the package states. Like the cheaper products. It’s too short to do much anything is why I removed a star.Using this for a portable air conditioner window mount exhaust. Or for the wall mount into the duct system.⭐️⭐️⭐️⭐️

This was perfect for my needs, cut smoothly with normal scissors.

The thickness of this insulation is such that it makes it very inflexible. It's hard to tell from the product images and description.... It's not like the thick, heavy duty spongy insulation I expected to get --- it's more like semi-flexible rubber. No way this material can be worked into gaps .... Far too rigid. Works well for filling in something like a track or channel --- like the bottom track in a window frame when installing a window air conditioner to eliminate that air flow channel and take strain off the window frame. I bought it to fill in gaps when installing window air conditioners, but its unexpected inflexibility made it virtually useless for its intended purpose.

foam material is non-toxic and environmentally friendly, making it a safe choice for use around the home. Its white color blends seamlessly with most air conditioner units, maintaining a clean and professional appearance.

I love that it's white, works great for sealing the gaps on your portable floor model air conditioning units.The black that most vendors sell for AC sealing looks hideous from the inside and the outside of your window. This is the best product for sealing the window gaps on portable AC units I have used.

White shows less than the black, and it's a firmer material than what's at the home-improvement stores. Easy to cut to size. I used it in that gap between the glass in the upper sash and the glass in the lower when the window is opened for the air conditioner.It's short. Could only do one window. But it didn't cost that much.
