Thanks Paul, I confirm the wool pile is 6/16" (or 3/8") high [I've measured it multiple times].
I've browsed Swisco's wool pile selection and didn't find any with the specific dimensions I'm seeking. I may have to try the 3/16" base and see if one with the shorter pile height works adequately.
Thanks for you help. If any other reader of this post has suggestions, they are appreciated.
Thanks! I'm glad I could help. Let me know if anything works out for you.
The fin seal helps to keep out air infiltration. However, there's a possibility that it could make your sash harder to open and close. If your window has a little play in it, it may help, but I find that a good rule of thumb is: if your original woolpile has the fin seal, then replace it with fin seal. If it is a regular pile, then replace it with a regular pile.
Thank you for your guidance and assistance, Paul.
Also, I found your Discussion board was terrifically helpful and contained a trove of great information. Thanks for the very quick responses.
Best wishes,
Of course! It was my pleasure. If you have any other questions, please let one of us know, and we would be more than happy to help you.
