All the windows and polycarbonate roofing panels on my 20 year old uPVC conservatory are held in by uPVC glazing beads, fitted with rubber a sealing strip which has quite a complex cross-section - see
I would be very grateful for any help both in namimg them correctly and in suggesting suppliers who might be able to supply this stuff. The original conservatory suppliers have long gone out of business, so I can't ask them! I have a feeling that they got their materials from Germany at the time, but I'm not certain of that. As far as size goes, the max horizontal dimension (in the orientation of my photo) is about 20mm and vertical 9mm.
TIA.
