A curtain wall is definitely an external swaddle of a building in which the surfaces are nonstructural, meaning they do not " contact form part of a structural program but may from time to time be subject to causes other than their own weight. вЂќ( Windapo, A. 2012. Study course reader). The curtain wall membrane building that we visited is usually ABSA Center Cape Community, which is the first aluminium-framed building in Cape City to use a constant glass drape wall. This type of wall is different from other types by their construction technique and the types of elements used.,

The moment erecting this kind of building, the elements that include aluminium beams and content, concrete articles and slabs and the non-load bearing infill panels (which in this case are glasses), happen to be " constructed and glazed in the manufacturer, shipped towards the site and erected on the buildingвЂќ(Vigener, And. 2011. Building Envelope Design) using tower system cranes. The construction process generally involves affixing or hooking up these manufacturer made materials to the aluminium frame applying welded screwing, bolting or perhaps joint sealants to join the glass to aluminium. This type of wall construction is faster and budget-friendly since it could be easily installed and managed compared to other types like masonry walls though on large projects an appropriate and careful design, which in turn takes into consideration the Nationwide Building Rules (NBR) requirements such as; drinking water penetration, structural strength and stability, behaviour on fire, moisture build-up or condensation, thermal expansion and shrinkage, thermal movements and visual, is necessary. Beams, which support the floor as well as the roof program and posts, which carry the beams and transfer the loads to the foundation, are made of aluminum. Aluminium material is the best choice to become used in a sizable curtain wall membrane project since it has large strength-weight ratio, low thickness, good agent of thermal expansion and also because it withstands corrosion.
