Looking for replacement window weatherstripping

A home owner from California says:
I'm replacing weatherstripping on my 35+ year-old aluminum windows. The track in which the window rides appears to be 1 1/32" wide (maybe 1 1/16" in some places) and the windows themselves are 7/8" wide. The windows take pile weatherstripping in 9/32" channels on both the inside and outside.

1. What thickness of pile do you suggest?

2. From another supplier I obtained zipper pile carrying the CR Laurence name, in more than one thickness. I do not think the quality is good, as the pile fibers come off too easily. (Small remnants of pile with a non-zipper-type backing from an unknown source that I obtained from a local window shop were much better.) Do you sell material from the same manufacturer, and does your pile behave this way?

3. Is this possibly an issue with zipper backing in general? Zipper backing is certainly easier to install but I'll go with a non-zipper backing if that's what it takes for better durability of the fibers.

Hey, Ken. We carry many different seals with a 9/32" backing, but I'm not sure what height you need. Start with our 58-099, 58-105, and 58-126. Could you get any of these to work?

I can't speak for the manufacturer who made the wool pile you dealt with before. Our wool pile is of a great quality and we've never heard any complaints about it falling apart. It's possible the sample you had before was old or brittle. Wool pile starts to break down like you describe when it gets old.
