I have Andersen Perma-Shield, Gliding Windows that were installed in 1973. On the glass is the marking- 12 AW 72 XI. The frames are in fine shape but the weather stripping is cracked and broken or missing. On windy days the curtains move and here in NH that is costly. 3 are approx 4X8', 2 are 4X5' and 6 are 3X3'.
I can take the sashes out but don't know what to do from there. Has anyone replaced the vinyl insulating strips adhered to the sash and the vinyl runners on the sill track?
I can see the various parts here http://www.andersenwindows.com/homeowner/pdfs/PS_Gliding_Window.pdf
Thanks for the help,
