I need replacement weatherstripping for my 1988 -1990 Kolbe & Kolbe casement windows. I've replaced the sash stripping with your bubble seal, but discovered that I need the interior weatherstripping as well. That product worked exceptionally well.
This appears to be a bubble seal also but its attached to a hard plastic that fits into the window frame. Also the bottom piece appears to be different than the top and sides.
Can you please direct me to one of your products for replacement?
Thank you,
John
