Weatherstripping is flat strip 5/8" wide in total. 1/4" is relatively stiff and has two 1/8" barbs for holding in channel on window frame. The remaining 3/8" is more flexible. It is made of some sort of vinyl-type material.
I need to replace the weatherstripping on all four sides of numerous windows, so I hope there is a replacement available in rolls that can be cut to length.
Thanks.
