(57) Flush-fitting door whose surround is made up of welded-together hollow PVC sections
(2-6), and in which the panel (7, 8) is held between strips (15) disposed on the PVC
sections (12) and strips (18) which slot behind flanges (16, 17) provided on the PVC
sections, the strips (15, 18) being designed in such a way that they lie fully within
the section thickness.
The section (12) for the surround is preferably a tubular section (13) with at least
one partition (14) which is provided on one side with the fixed strip (15) and the
snap-in flanges (16, 17) for fastening of an insulating panel or insulating glass,
and on the other side has two double-walled strips (20, 21) which are flush with the
outsides of the tubular section, and between which an open chamber (22) is formed.
The inside walls (20', 21') of the double-walled strips (20, 21) are provided with
raised parts (23, 2) (sic), and along the top cross-member (2) and the jambs (4, 5)
of the surround an auxiliary lath (35) which snaps into the said raised parts and
closes the open chamber is provided.
It is advantageous if provision is made, on the double-walled strip at the contact
side of the door, for a groove (25) with raised parts (26, 27) lying opposite each
other in the opening, for the fitting of a sealing strip.
