ADVERTORIAL Metal roofing is regaining popularity in residential applications. T he challenge for the global construction industry is to meet the world’s growing needs while also limiting the downstream impact of its activities. Steel is increasingly important as a material of choice as it offers a wide range of solutions that make buildings more energy efficient, less costly to construct and occupy and therefore more sustainable. The challenge for the global construction industry is to meet the world’s growing needs while also limiting the downstream impact of its activities. Steel as an ideal construction material: Steel’s high strength-to-weight ratio reduces a building’s environmental impact and conserves natural resources; it requires less material than traditional construction technologies. Steel roofing works wonders in low-cost housing: It incorporates green building elements into low-cost housing developments, affording greater comfort and lower costs to those who can least afford to foot high energy and water bills. Steel roofs allow for easy integration of green technologies: Water harvesting is more hygienic off a smooth surface (such as steel) than off a surface which harbours dust. Steel roofs are also competitive with the installation of solar heating panels and are entirely watertight when junctions are sealed. Steel is the most recycled material in the world: It is 100% and indefinitely recyclable, without any quality loss. Recycled steel represents 40% of the steel industry ferrous resource in the world. Steel provides more comfortable housing: Aluminium zinc roofing is highly reflective and is available in cool colours which absorb less heat. Steel also holds less heat over a period of time. Steel roofing is up to 4% cooler than clay or fibre cement roof coverings. Aside from its green credentials, steel is also fire retardant: It provides a high degree of personal safety for occupants as it is estimated that 15% of criminals who commit burglaries access buildings through a tiled roof. Government is going green in meeting its national objectives: In partnership with the Council for Scientific and Industrial Research (CSIR), the Department of Public Works (DPW) has developed a Green Building Framework. This framework also seeks to introduce a green building skills development and training programme, enhance research and development on the subject and establish centres of excellence on green buildings. This is a wonderful and exciting case of working towards ‘a better life for all’. Versatile: Available in a variety of profiles, including one with a tile aesthetic. Historic restorations call for durable, but beautiful roofing. O C TO B E R 2 016 11
