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
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
• 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
• 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.
