There are many definitions of Curtain Wall.
Basically the name is derived from the concept
that the exterior skin hangs on the superstructure
like 'drapery', and does not bear the weight
of the building itself. The term 'Window
Wall' is often used to describe a special
category of Curtain Walls made only with
glazing components. Aesthetics: Typically, a Curtain Wall is
the most striking visual element of the building
from the exterior. It is what initially draws
'Tenants' to rent or purchase office space,
and this is our Client's primary objective. Structural: Even though a Curtain Wall does
not carry any of the building's loads, it
must support its own self-weight, resist
imposed wind loads, and remain structurally
sound throughout its design life.
Weather-Resistance: Basically the Curtain Wall separates the exterior climate
from the interior controlled climate. It achieves this through 'Thermal Insulation',
providing a 'Water Barrier', and reducing 'Noise Levels'. Design: The design of Curtain Wall typically
involves several parties. The manufacturers
of each individual component provide materials
already designed to meet certain pre-established
criteria. However, the connections between
different systems and selection of components
are left to the Project Designer. The responsibility
in this area usually rests with the Architect
and Engineer, and in some cases the Curtain
Wall Contractor is charged with these responsibilities. Materials: The material selected for each
individual project usually relates to the
Clients and Architects choices, however,
local availability and climate zones also
play an important factor. Materials must
be chosen carefully to ensure the building
maintains its appearance over its design
life. Construction: The overall quality of the
Curtain Wall is dependent not only on good
design, but also the way it is assembled
in the fabrication plant, and the way it
is erected in the field. The Curtain Wall
contractor has a major responsibility in
this area. Operation: After the completion of the
Curtain Wall installation, the continued
performance is dependent on the 'building
maintenance'. The system and equipment utilized
to carry out maintenance duties must be suited
to the type of Curtain Wall. |
