Does anyone know how to identify a window manufacturer? My house was built in the late 1980s. The windows are casement windows(crank out stile/Anderson-type). Ideally I would like to find the manufacturer and hopefully buy frame molding in order to repair wood rot to some of the frames. The window glass does not have any identification markings etched on the surface of the glass, but there is a marking stamped on the plate separating the panes of glass. The markings on plates from two of the windows are: D23187X36B2 D34287X26B2 i also have doors that look like they are made by the same manufacturer and the glass in the doors have etchings that read: PPG HERCULITE K TEMPERED SAFETY GLASS BS6206A 16CFR1201 CII ANSI Z-97.1-1984 1/BU 5GCC-250 6013387 If I am not able to identify the manufacturer, can I buy frame molding that is the same width and thickness as what is on my windows to build new frames? Or another thought am I wasting my time trying to repair the windows and should I just bite the bullet and buy replacements? Thank you.
