I can only speak to US terms, but GS has parameter terms backwards on all its metal window library parts in the 9.0 library. A window "frame" is the portion of the window that fits in the wall opening and is attached to the wall. A "sash" is the portion of the window that fits within the frame and holds the glass or glazing. For fixed Metal or Alum. windows there usually is no "sash".
Graphisoft, please correct this. The odd thing is you have it correct for wood windows.
Thank you!
