The existing pile measures with a 1/4" wide tab and 1/8" deep pile. (see the first three photos).
Some of the windows are slightly bowing inward (from years of wind pressure perhaps) resulting in a gap of about a 1/4" (maybe more .. it's hard to measure but you can see in the fifth photo my fabric measuring tape fits easily in the gap even with the existing pile) -- this means when the window is closed the pile is not making contact on this portion of the window. If I press on the window frame I can close up the gap. I'm wondering if I should use deeper pile on this portion of the window or if there is a better solution (or just something to live with!).
What should I be using to replace this?
One more question (fourth photo): There is a metal thing in the base of the window I removed to get the pile sample. I took a photo of it (the fourth picture). Is this part of the frame? something that fell out of the sash? something else? Just curious!
Thanks!
