ABSTRACT:
An elongate frame member of uniform cross-section is provided for a combined door and window frame assembly. The said frame member is adapted to divide an outer perimeter frame into two areas, one to accommodate an opening window and the other to accommodate a sliding door in its closed position and comprises a rigid supporting portion, an elongate recess of L-shaped cross-section to receive one edge of the window and an elongate flange connected to the supporting portion and spaced therefrom by an intervening web, said flange being so positioned, in the assembled frame, that a part of the sliding door when closed can engage between the flange and the supporting portion to facilitate a draught proof seal.
