M-D Building Products 43846 3/8 in. x 3/8 in. x 17 ft. White Premium Silicone Rubber Platinum™ Window Seal for Ex-Large Gaps

The Adhesive is not sticky enough to keep in in place upside down, almost enough but not quite.More so the issue I had was the last maybe foot or 2 is all crumpled up because of how they packaged it. Due to the weak adhesive I cannot get it to stay flat on something, you basically lose 4 feet of this pricey product(for what it is).

I have a large patio window that is 20+ years old, and the wood frame started to warp from the sun over the years, so during windy days the windy blows through the tiny gaps and makes high pitch noise. I tried many weather strips to no avail, but this one actually works. I don't know what makes this one different from other seemingly identical weather strips, all I know is I bought 10 of these for all my windows and doors, and they are still going strong after 4 months when all others failed after weeks. The adhesive on this one is a bit on the weak side, but nothing some Gorilla Glues won't fix.

They do work awesome and reshape after long periods of pressure load.

For those occasions when good, ol' fashioned  Duck Brand brown duct tape  won't do the trick, this is an excellent, sturdy, and sticky product. It was recommended that I try using weatherseal around the frame of our door for soundproofing. We have had a serious noise problem, as our condo faces a loud common-area whose open space amplifies sound. Residents and foot-traffic generate noise that travels right into our unit. Since we were desperate for a modicum of peace & quiet, we thought we'd give this product a try. It was easy to apply around the door's frame; the silicone "wave" profile really does expand & contract to seal gaps. The brown color blends in unobtrusively. Now, there is a marked difference in the amount of noise-intrusion, for which I'm grateful. This M-D Building Products weatherseal provides an effective barrier not just to minimize dust and temperature variation, but against noise. Highly recommended!

It sealed an air leak on my front door perfectly. The dual bead helps. We

Just got this to help seal an indoor swinging door. The product works well and I am sure will help with cooling now and heating this winter. A word of warning the package and the description say 17 feet, our package had 10 feet at the most. Amazon customer service is sending out a second package and will be looking into this but I wanted everyone to have a heads up as of now these run 7 feet short.UPDATEJust got the package that Amazon shipped out and it is also 10 feet long.

We just purchased a house in Massachusetts, land of taxes and cold winters. The previous homeowners had done a terribly poor job of winterizing the house. By that, I mean they had basically done nothing, so there were drafts coming in all around the doors and windows. When I saw this product, I thought it could be the answer to reducing drafts and hopefully our sky high heating oil bills. It did work for a while, but then the product started losing its stickiness and portions would just peel up and hang off the inside of the door. I would try it again to give it a second chance, but it is frustrating to need to spend more money to keep fixing the same problem.

This seal was easy to install and use and I saw that the draft coming through my windows immediately stopped. The only issue is that the adhesive could be improved, as the seal didn't stick well at certain points, but since I don't always open the windows, it's not a big issue for me.
