Soezy 16 Ft (5m) 196 Inch Sliding sash Windows Doors Tape Pile Draught excluder Brush Seal Strip weatherstrip 5mm x 6mm (3/16 1/4 Inch, Gray)

This is a brush style thin strip insulation that fits the groove on the sides of the flap on a doggie door. It’s designed to slide in the groove from the top which is not possible unless you took the door apart. But it works if you have a pointed round tool like they show at the bottom of their description page. Once I dug out the old strip bit by bit, I was able to insert the new strip the same way but I had to also use a small head thin screwdriver and push on both sides of the strip to get it in there. The backing is stiff and helps hold it in, just be patient and push both sides in all the way to the finish. No glue is needed. It worked well and our flap is tight once again! No more leaks or flies.

Summary from my experience, as someone who’s installed hundreds of weatherstripping products for various applications:• good pile, wouldn’t mind ~slightly~ higher density, but I’d say it’s definitely sufficient• DOES contain center polypropylene fin (this is GOOD as it acts as an airtight barrier - not many others I’ve come across on Amazon have this)• flexible backing (this being good or bad depends on what you need, in my case it was good, but you decide for your application)Now, for the sake of future viewers, to address all the unnecessary negative reviews others wrote due to it not having adhesive:1) it clearly shows there’s no adhesive2) stop writing bad reviews because you don’t know how to use a product and you’re in over your head, or because you didn’t check description.3) adhesive weatherstrip is NOT a long term solution. You will not find any remotely decent product that uses adhesive as the main retention for its weatherstrip. Instead, this type of weatherstrip slides into a channel where it is mechanically retained and will stay as such until the weatherstrip itself wears out.I just wanted to clear this up for future readers, as I think it’s unfortunate when I finally find a good product, but is flooded with negative reviews from people who simply don’t actually know how to use the product.

Works

Before I ordered the weatherstrip, I measured the old one twice to make sure it would fit. It fit perfectly into the channel on the window. To prospective buyers always measure before you buy. Also this product does not have adhesive. I did not want an adhesive product.

Compared to the old weather stripping i had on the door, which i got from a professional door parts supplier, this new stuff is kinda cheap. It not as thick or heavy duty as the old weather stripping.

There is enough product in one packet to redo one sliding door. The install wasn't difficult. From what I learned, it's a good idea to replace this seal every 7 years or so. Anyhow, this product worked fine and seemed equivalent to what was original or came installed with door.

Turned out to be the correct size to fit my 45 year old windows.Worked well to stop the drafts & noise infiltration.

This replaced the worn seal perfectly. Measure your gap and add about 1/8" or 3mm and order that size. Fits nicely and seals well. Seems to be of good quality. Mine had no adhesive on the backing (some will, check yours first) and was simply held in place by a small crimp in the channel which was opened by a steel puddy knife tapped down the channel with a small hammer (gently) to open it. The top and bottom of the windows were like this. The vertical portions were held in place by interference fit with the horizontal ones on the top and bottom. If they're loose in the channel and slide easily (mine fit nice and snug but could be slid in by hand to install) simply add a small drop of glue at the end. It will take very little. Good product.
