Point Fixed Glass System Curtain Walls is a system for point-supported vertical glazing in which thermally toughened (Tempered) glass sheets are used, in single glazing or in insulated glass. Laminated safety glass (tempered laminated glass) is preferable to be used in single glazing or as the outer sheet of the insulating glass units.
This system consists of a number of accessories with metal arms. At the end of each arm, a sheet of glass is fixed by the corners with a special screw. The vacuum between these sheets is filled up with isolators to overcome mechanical pressure and weather conditions.
Point Fixed Glass System Curtain Walls are used most frequently in structural glass curtain walls to create transparency and depth of vision for the occupants.
The glass panes are either bolted or clamped with components providing attachment to the structural system. The most common system type is often referred to as a “spider” system. The metallic fingers that support the glass façades allow the designer to increase transparency by minimizing the structural framing.
A four- armed fitting, usually of cast stainless steel, supports four glass panes at adjacent corners on the glazing grid and ties back to the structural system. The spider fitting is designed to provide for glazing system movement under environmental loading, as well as to accommodate specified field tolerance during assembly. A variety of spider systems are available from the suppliers of cable and rod rigging systems.
Cast stainless components can be quite expensive, especially if large, customs spiders are required, as they often are in large glass grids. Alternatively simple stainless spring plates have been used in place of a cast fitting with excellent results.
Point fixed glass - Bolted:
The approach for the point-fixing of glass, since the development of the suspended glass wall, has been mechanical attachment with a fitting that accommodates a bolt through a hole drilled in the glass panel that ties it to supporting structure.
Multi-layer glass panels presented a particular problem at the start of the point-fixed systems. A method had to be found to seal around the fixing component so as not to compromise the air cavity of the panel.
Glass manufacturers and fabricators developed a ringed spacer that could be sealed around the holes to this purpose. This development has made the sourcing of this type of product become easier and more competitive worldwide.
Toughened glass is a requirement to accommodate the stresses concentrations resulting from bolting directly to glass façade plates. Planar fittings support the dead weight of the glass by direct bearing on the bolts, so it is critical to maximize the strength of the glass around these joints.
The bolt holes are diamond drilled into annealed glass and subsequently heat soaked to assure that nickel sulphide inclusions do not cause spontaneous fracture of finished glass panels.
Point fixed glass - Clamped:
Bolted method of point fixing has the disadvantage of requiring drilling and countersinking of the glass panes, and with insulated glass units the insertion of a sealing ring in the space between the glass panes around the bolt hole.
Each laminated or insulated glass unit requires the drilling of at least eight holes. Insulated-laminated panes require a minimum of 12 holes. Obviously, this adds to the cost of the glass panels.
An alternate approach that eliminates the need for drilling and instead clamps the glass at the perimeter is frequently referred to as a “pinch-plate” system. With a spider-type system, the spider component is rotated 45 degrees so that the spider arms are aligned with the glass seams.
A narrow blade of metal penetrates from the spider through the center of and parallel to the glass joint. A relatively small clamp plate on the outside surface of the glazing plane is then fixed to the blade, clamping in place the two glass panels on either side of the seam.
Another approach, frequently employed on cable nets, is to set the glass into a specially designed clamp component tied to the supporting structure. A cover plate is then attached over the outside corners of the glass, effectively clamping the glass at the corners. Neoprene pads are used on both faces of the clamps to protect the glass.

Features of the Point Fixed Glass System Curtain Walls (spider system):
• Engineers and modern architects have designed this system with a main objective of getting the most possible transparency and thus the clearest vision which is normally hindered by using the various constructing elements.
• The spider system offers practical solutions to glass assembly that no other system can provide.
• To fix the glass up at the edges of the facade, one or two arms-accessories can be used. In special applications, the number of arms might be more than two and the sheet of glass can be fixed by one arm at each corner.
• The used accessories can be mounted against metal frames or against glass fins and tension rods are used to pull these accessories together.
• Single, Insulating and laminated glass can be used with the spider system. The thickness of the glass depends on the specifications of the project; therefore a special study is performed for each project.
• When the spider system is chosen, halls will be applied to glass before being assembled. Therefore, tempered glass should be used.
