Curvature with an acoustic benefit


An elegant curvature which has also helped deliver an acoustic benefit in an area prone to severe storms is a striking feature of extensions to the National Research Foundation building in Persequor, Pretoria.

One of the two new wings built for the foundation, the government mandated research and science development agency, houses an auditorium and entertainment area while the other comprises offices.
In designing these wings, Snapp Architects repeated certain design features to maintain the rhythm of the existing building and also opted for the innovative contemporary building material that is RHEINZINK zinc alloy. RHEINZINK was specified as cladding and roofing material to form the elegant curvature on the northern facade of the wing housing the auditorium.  No other product could provide the radius sought by the architects.

The substructure required for the RHEINZINK installation also helped to achieve optimal acoustics inside the auditorium - an added advantage since having metal roof sheeting on an auditorium in an area prone to severe rainstorms and hail can be problematic.

Known for quality, durability and lasting value, RHEINZINK - such as the selected RHEINZINK-prePATINA  in graphite-grey - avoids the need for intensive regular maintenance that may result from use of in-vogue alternatives.The aesthetic patina created by natural weathering will protect the material for decades.
RHEINZINK requires little energy in production and is 100% recyclable, meeting today’s essential design considerations for sustainability and low energy use.
