Structural curtain wall (aluminium and glass)
HP 6800 SERIES
Alumico Architectural Inc
Fabrication of the system shall be made according to the rain screen principle. The rain screen principle applied to the curtain wall system is based on pressure equalization. All joints shall be constructed to prevent entry of water into members. Outside extrusions shall be 63,5mm (2 1/2") wide and inside extrusions shall be 65mm (2 9/16"). The depth will be sufficient to provide the required structural properties (consult wind load chart). The structural part of the system shall be the inner mullion. The assembly of the horizontal and vertical mullions shall be made by means of extruded aluminum shear blocks and hidden screws. A pressure plate fastened to the mullion will secure the insulated glass unit from the outside. A P.V.C. extrusion shall make a thermal seal between the inner mullion and the pressure plate. An outside snap-on cap shall conceal the pressure plate and its screws. The perimeter of the glass shall be sealed by a flexible glazing gasket on the inside and the outside. A door adapter extrusion assembled with the inner mullion shall allow for door installation within the curtain wall system. Such assembly shall respect the 63,5mm (2 1/2") overall width. This door adapter shall allow for replacement of the glass units adjacent to entrances without having to remove the doors from the frame.
The 6800 Series curtain wall meets the FIXED, B7 and C5 performance levels of CSA A440-00 Standard.
All aluminum components shall be made of 6063 alloy with T-5 temper.
