Modular Glazing 40 Range.

Classification
A system of narrow sight line glazing bars and transoms designed on the drained and ventilated stick principle for use primarily in vertical and inclined patent glazing applications.
The cruciform bar configuration sections can be used up to l 200mm modules dependent on spans and glass types. They are designed on the two edge glass support method as defined in BS: 5516.
The box sections are designed on the four edge glass support method with the benefit of wider modules. Dependent on spans and glass type modules up to 1500mm are possible.
Single glass and 24mm thick double glass units can be fitted, although not in conjunction in the same mullion/transom.
Various opening windows, louvres, panels and doors may be directly "glazed" into the Curtain wall grid.

Materials
Aluminium sections shall be extruded in accordance with BS: l474 from 6063 alloy in the TF condition. Associated pressed metal trims shall be from aluminium sheet in accordance with BS: 1470
A) Designation l200 for mill and paint finish
B) Designation 5005 for anodised
All screws or bolts used externally shall be stainless steel designation 304 S I 7 in accordance with BS: 3111 part 2.
Screws or bolts used internally, shall be mild steel or high tensile steel, cadmium or zinc plated and passivated in accordance with BS 1706.
Glazing gaskets and thermal barriers shall be of extruded black EPDM in accordance with BS: 4255.
Glass shall be manufactured in accordance with BS: 952 and fixed in accordance with BS: 6262 and BS: 5516.
Steel fixing cleats shall be mild steel shotblasted and de-greased and either galvanised to BS: 729 or zinc, phosphated and stove painted.
Aluminium fixing cleats shall be extruded alloy ref 6082 in the TF condition. They shall be mill finish as standard offer but paint or anodised finishes will be considered.
Interfaces with structure shall be fitted with PVC tape.

Construction
The glazing mullions shall comprise either extruded aluminium box or cruciform profile sections. Projecting legs shall incorporate integral extruded gasket retaining grooves and channel to receive clamp fixing screws. Concealed drainage channels are included.
Extruded aluminium transoms shall interlock into the mullions and drain into the mullion drain channels. Narrow depth and full depth transoms shall locate on stainless steel pins.
Glass shall be retained in mullions and transoms by means of a continuous extruded aluminium glazing clamp. This shall incorporate integral grooves to retain glazing gaskets and thermal break sections. The clamp shall be secured to mullions with No. 14 self tapping screws at 300mm centres.
The glazing clamp shall be covered with an extruded clip on cover, concealing the clamp and its fixing screws.
All covers are 40mm face width. Standard mullion covers project 22mm from the glass face. Transom covers project 20mm from face of glass.
Standard profile extruded head and cill members are available and should always be used with cruciform profile mullions.
The cill provides a 35mm drip protection and incorporates extruded clip in draught bead with integral gasket.
The head section is an inverted angle profile incorporating the same draught bead as the cill and with grooves to accept the location of adjustable cast aluminium fixing spigots. The head and cill of box profile mullions is usually formed with transom sections incorporating a pressed aluminium drip flashing profiled to suit individual contract details.
Joints in mullions are sleeved with allowance for thermal movement. Purpose designed angle cleats connect mullions structurally and form tie back brackets to structure.
Glazing mullions and transoms are delivered to site in bar form for assembly.
