Frost KingAC42H Air Conditioner Weatherseal Tape, 1-1/4 by 1-1/4 by 42-Inch,Black

This product is absolutely perfect.I can use it for multiple things. In the winter I use it for insulation against the cold and in the summer, I use it for the space left inbetween windows from my window AC unit. It is easy to work with and the thickness is perfect!

Perfect for sliding glass doors

While there was some unknown delay in receiving my shipment (it was said to have delivered over a week ago) it showed up today at my post office, and I am thankful. I live in a rural area...and while deliveries typically go smoothly, occassionally there are mix-ups unrelated to the seller. I am thankful that it arrived, and I am tremendously happy with the product and with whomever made certain that I received it. Great product, company and seller, in my book! THANK YOU!

Product standard for installion. Delivery time was unusually long.

Purchased half a dozen on sale @ $2 each. They cost more at brick and mortar stores, so I stocked up. Couldn't find anything this same size any cheaper and they fit between the window panes as good as the pieces of foam that were included in the AC units.

I've been using these for years to seal around my window air conditioner. They work great and are easy to use.

I make sure to clean my air conditioners yearly. Always install on a slight 1/4" angle to keep water out(use level). But make sure top of the window is sealed. And the bottom window nearest air conditioner, has a stuffed one of these in it near the locking mechanism. Many don't know that hidden space let's warm air in or cool out. For a few bucks, each one should have one of these. You can use a scissor to cut to the width of your window. For longer windows, measure and buy two. I use the leftovers to seal or stuff cracks.

I was shocked at how well these foam things stopped a draft. If you have a wide living room window like mine that’s metal and slides from each end toward the center, you may want to get a couple of these. I got some to put in the small gaps around my below-the-window-and-thru-the-wall AC. I dropped the extra one into the bottom of the center window which is the center pane between the two sliding ones, and I noticed an immediate difference. The foam arrives sort of curled, so it may need time to straighten out before you place it.
