Fitting 6.1 General information The following guidelines for glass and glass ceramic apply to the fitting and handling of ROBAX®: • The different thermal expansion of ROBAX® and the various frame materials, together with possible manufacturing tolerances, must be taken into account when sizing frame and panels. • If it is necessary to use compression fixing of the panel in the frame for design reasons, the pressure must be applied uniformly (never unevenly or at individual points) around the periphery of the panel. • Non-distorting frames should be used. If slight distortion cannot be avoided, a suitable permanently elastic gasket must be used to prevent the distortion of the frame being transmitted to the glass ceramic panel. • Direct contact between glass and metal (or other hard construction elements) must be avoided. We recommend permanently elastic heat-resistant materials such as mineral fiber materials as an insert between the glass ceramic and the metal. Perfection is a question of more than just materials and design. Correct handling is important as well. Make sure you are always on the safe side by complying with the appropriate guidelines.

If using ROBAX® for such an application, please comply with the following basic points (the general information under point 6.1 naturally applies as well): • The weight of the panel should be distributed across rails of a sufficient size. Stress on specific points, e.g. caused by the weight of the panel “resting” on the screws/bushings, should be avoided. The pressure forces transferred to the glass by the rails must be absorbed with a suitable material that is both temperature-stable and flexible (e.g. glass-fiber cord between hinge/handle and panel). • Contact pressure on the panel which could lead to it bending under force is to be avoided. This can be accomplished with the restriction of torque or a mechanical stop limiting the screw penetration, for example. • The closing of the door should not cause any additional pressure (leverage) on the side of the panel mounted with a hinge. • The hinges should not jam during closing, as the corresponding resistance forces could be transferred to the glass during opening or closing of the door.
