Aluminium curtain wall is a term used to describe a building
fa?ade which does not carry any dead load from the building other than
its own dead load, and one which transfers the horizontal loads (wind
loads) that are incident upon it. An aluminum curtain wall is designed
to resist air and water infiltration, wind forces acting on the building,
seismic forces (usually only those imposed by the inertia of the aluminium
curtain wall), and its own dead load forces.
Aluminium curtain wall are typically designed with extruded
aluminium members, although the first aluminium curtain wall were made
of steel. The aluminum frame is typically infilled with glass, which provides
an architecturally pleasing building, as well as benefits such as daylighting.
Aluminium curtain wall differ from storefront systems in that they are
designed to span multiple floors.
The loads imposed on the aluminium curtain wall are
transferred to the building structure through the anchors which attach
the mullions to the building. The building structure needs to be designed
and account for these loads. In the case of aluminium curtain wall, this
load is made up of the weight of the mullions, anchors, and other structural
components of the curtain wall, as well as the weight of the infill material.
Additional dead loads imposed on the aluminium curtain wall, such as sunshades,
must be accounted for in the design of the aluminium curtain wall components
and anchors.
