THERMWELL - 1-1/4 x 1-1/4 x 42-Inch Air Conditioner Foam Weather Seal

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.

I never messed with installing a foam strip on top of the window sash with the air conditioner in until one morning there was creature on top of the curtain. A sparrow apparently came up between the sashes. I always thought about maybe a bee or a fly coming in, but it never seemed to happen. A bird, go figure.

Worked well between windiw and AC

It worked exactly as expected, and since it clearly stated 42" in the description and the picture I was not expecting any more than 42."

Product standard for installion. Delivery time was unusually long.
