Profiled polycarbonate for cooler roofs

The energy-efficiency regulations for buildings, which came into effect in November last year, have steered the South African building industry in a more eco-friendly direction. One issue that has been raised in this context is the urban heat island (UHI) effect, which occurs as a result of a concentration of buildings, hot surfaces and waste heat from human activity that creates a warmer envelope of air over urbanised areas. This not only taxes the air-conditioning systems in buildings, but also increases pollution levels significantly.  Christo Pienaar, marketing director of Modek, a company which specialises in glass reinforced polyester (GRP) and polycarbonate roof sheeting, says that cool roofing is a real solution to the problem. “Cool roofing is one of the simplest and most cost-effective solutions to diminish the UHI effect and it supports energy efficiency in buildings.”
