eastbay is correct that while the A series sash is fiberglass, Andersen does use fibrex in the frame.
My apologies for any confusion on that one. The last time I chatted with "someone" at AW about the A series they said that they were going to be full fiberglass; however my bad that I never followed up on that one before replying about the actual make up of the finished windows/doors.
If I recall correctly AW did look into both full fibrex and full fiberglass during development of the A series and I also seem to remember that they did produce full fiberglass versions of A series units at one time, but I don't know if they ever actually sold any that way.
Per "someone" who absolutely does know, A series is like 200 and 400 series in that the frame is actually clad wood rather than just fibrex (A series) or vinyl (200 and 400).
So to be precise, A series units use fibrex clad wood for the frame and pultruded fiberglass for the sash.
Again sorry for any confusion that I might have caused.
