rr'H E accompanying illustrations show the new Duilex 1 system of glazing, as introduced by the Rawlings Manufacturing Co., Ltd., 1-29, Larch Road, Balham, London, S.W.12. The chief advantage claimed for this new method is that the operative can see what is happening to the glass panel the whole time, as opposed to the "taking it for granted" method most usually adopted. Furthermore, no excessive pressure is required to install the glass into the metal pan and the removal-of a cracked or broken pane is readily carried out, and without the possibility of causing damage to the paintwork. Reference to the drawings will show that, in the Duflex system, there are two rubber units, complementary to each other in design and purpose, and to the specially shaped metal pan. The first of these rubber units is designed so that it may be fitted, not to the glass, but to the metal pan,to provide a seating, or bed, upon which the glass pane, with all its edges visible, may be placed. Mounting the pane is the next operation, after which the second rubber unit is pressed into position. The ease of removal of a cradled or broken pane will readily be appreciated, it being the work of only a few seconds to prise up the secondary bead and to pull it out by a sweeping and sustained action around the perimeter of the pan.
A most important feature of this new system lies in the n28
protection afforded to the metal work, as it will be noted that the retaining bead of the rubber section embraces the vertical interior flange of the pan section, so preventing water trickling down the glass on to the flanges of the pan. The three stages in the Dufiex system of glazing: (A) First rubber unit fitted to pan. (B) Introducirw the second rubber unit. (C) The pane firmly but resiliently secured in the window
