COLORBOND® steel with Thermatech® solar reflectance technology sets new benchmarks, providing Australia’s property owners, architects, builders and developers with better choices to meet the challenges of a changing world.

Thermatech® technology optimises the solar reflectance properties of 21 COLORBOND® steel standard colours. With Thermatech® technology, even the darker colours in the COLORBOND® steel range perform better without changing their appearance. So you can choose from a wider range of colours and still enjoy a thermally efficient roof.  (Thermatech® technology is not available in the colour Night Sky® and is not available in COLORBOND® Stainless steel)

In an Australian summer your roof is your building’s first line of defence against the hot summer sun that is high in the sky. Thermatech® technology helps your roof and your building stay cooler by reflecting more of the sun's heat. When heat is reflected away from your building, air-conditioning has an easier job keeping your building cool. Using less energy to cool your building can help occupants save money on energy costs as well as potentially reduce emissions from electricity generation.

In an Australian winter your north facing wall/s are the best part of your building to capture heat from the sun that is lower in the sky and insulation is an effective way of preventing heat loss. The "cooling" effect of a roof made with COLORBOND® steel with Thermatech® technology is greatly reduced in winter because the sun is lower in the sky, and days are shorter and often overcast.
