M-D Building Products 02006 1-1/4 in x 42 in Gray Foam Window Seal Strip – Air Conditioner Window Seal, Weather Stripping Foam Insulation for Window AC Units, Adhesive Foam Strip

Perfect product for sealing up air leaks around doors and windows the side of my house that faces where the wind blows I have trouble with a lot of air leakage around my sliding glass doors this was just the right shape and material I needed to fill the areas that need reinforced. Good product to help sure up some efficiency issues in your home at a fair price and extremely easy to use.

The 2" strips block even major gaps in windows. No more drafts. Strips are flexible and easily fit into tight spaces. This has made a difference of 5-10°F in the temperature of the room, due to loose windows.

used it for the wall unit ac / works great!

I bought one of these and it worked fine. Ordered two more and after a great deal of confusion they did arrive. I was happy to find a replacement for the original that came with the air conditioner and would buy more if these wear out.

Does exactly what weather stripping should do. Easy to cut to size and install, and it creates a solid seal that noticeably reduces drafts and outside noise. The foam material is dense and holds its shape well over time. Great for doors or windows that have gaps. Simple home improvement that makes a real difference - especially worth it in winter.

This was exactly what I needed. Was installing a diesel heater and needed to exhaust through a double hung window. Needed something to block air around the board I used. This worked great! Easy to press into the sides of the window jamb to block air from getting any further. Easy to manipulate/squeeze to get into tight spaces. Definatly blocks the cold air. The thickness was perfect, the quality of the material is great. I have some left over that I'll use with my air conditioner when summer comes.

Works fine except is does not have an adhesive side as advertised. Had to attach with double sided tape. Listed as "Adhesive Foam Strip" at the time of purchase

helps keep the cold air in and the bugs and warm air out

Really good quality & blocks drafts. Using it for winter drafty gaps under doors & it really works. The foam is soft enough to fill gaps nicely.

Just what we wanted for under the door. Very pleased with it.

It's foam, to be used with installing window air conditioners. There really isn't much to it. It arrived as described.. Got it to replace the one I used the years prior as there was an incident with my old AC, dirty water spilled over and saturated, so had to replace. Works just as well, except that the new one is nice and dry. Fills the gaps perfectly and helped with what turned out to be an effortless AC install.
