Research in the USA, Australia and South Africa continues to present the many reasons why clay brick construction, so widely applied in South Africa for house construction, deserves its pre-eminent status in sustainable house construction.

The newly legislated SANS 10400-XA: 2011 and SANS 204: 2008 introduce the requirement for proof of compliance with the standards set out for energy efficiency in buildings. This means that architects and building developers need to ensure that new buildings and building refurbishments are designed to meet the prescribed energy efficiency standards; that a building’s performance in terms of energy usage is calculated and documented; and that the building is built to perform accordingly.  Thermal insulation materials – for roofs, walls and floors – constitute a key element in building to achieve the required thermal resistance values (R-values) as set out in SANS 204.

The current economic crunch and the call for more energy-efficient buildings have led companies to reinvestigate the use of traditional construction materials and to consider alternative composites, such as glass reinforced plastic (GRP), for some applications.  Originally developed in 1938 for use in insulation, GRP is highly durable and combines a number of attributes including high impact strength, low weight, dimensional stability and weatherability. GRP has been used successfully in projects such as the new 3 050m² Masscash Holdings trading warehouse, contracted to Scheltema. The warehouse, with an apex height of 12m which affords the client flexibility in its racking layout and allows for bulk storage of up to six metres, was one of the first large-scale projects in the Western Cape to make use of the non-fragile GRP sheeting known as Modek GRP Walk-on.
