Spider Glass Façade Curtain Wall System (also named bolted pointed fixed type) 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.

The rectangular glass sheets have 4 or 6 countersunk drilled holes into which countersunk stainless steel bolts acting as point-fixings. The space between the glass sheets are filled with whether seal. The support elements that hold the fitting can be space frame, glass fin or tension cables.

The deflection of the point fixed glass facade is also important where the sway of the entire structure is being considered. Glass walls can be designed to have low stiffness and tolerate large deflections. The limit of deflections is determined by human perception of safety usually outlined in codes of practice.  Some glass manufacturers produce their system of joints such that the connection between the bolt and the glass is capable of carrying a small bending moment. Others make their systems allow rotation of the glass relative to the joint. Therefore, a detailed understanding of the allowable movement of the point fixed glass façade is required before doing any finite element analysis.

Glass plates in point fixed systems deform and therefore develop stresses when loaded with uniformly distributed surface pressure, like wind loads.

Deformations are elastic until they aggravate inherent flaws in the material and tiny cracks reach a critical length. If the flaw occurs near a concentration of stresses around a bolt, then the panel tensile stress resistance is reduced causing failure.
