Robertson Ventilation Industries designed, manufactured, supplied and installed two custom-designed sun louvre facades for the new Westcon head office.
For their new head office in the Waterfall Logistics Precinct in Midrand, Westcon required a vertical architectural feature that, in addition to enhancing the building’s appearance, would also block out the sun on two sides of the building.
Local ventilation and architectural solutions company, Robertson Ventilation Industries (RVI), came up with a custom-designed solution of vertical CPL 800/80 perforated aluminium louvres with a colour specification of RAL 3966 – matt white aluminium.
Manufactured at RVI’s manufacturing plant in Modderfontein, the vertical sun louvres were made from mild steel and aluminium. All aluminium and bracket components were powder-coated to SANS 1796:2010, to a thickness of 60 micron.
According to the contracts manager at RVI, Pierre van der Merwe, the perforated louvres block out direct sun because the holes on the facade never line up perfectly with the sunrays. At the same time, the perforation also makes it possible to see through the facade so that the view from inside the building is not completely restricted.
The two facades cover an area of approximately 540m². Due to the challenges posed by the size of the installation, RVI acquired the expertise of a structural engineer, THS and Associates, to help design the support framing that holds the perforated sheets. According to Van der Merwe, this was a crucial step to certify that the framing adheres to all the necessary standards in terms of wind loading and more, and to ensure that it is installed correctly without safety risks.
RVI designed, manufactured, supplied and installed the feature from start to finish.
“We are moving boundaries by creating bespoke designs, using new technology and innovative concepts,” says Van der Merwe. “Instead of going through a standard project catalogue and choosing a typical sun louvre system, clients now have many more options – on any size project.”
