What is Thermatech® technology and how does it work?
COLORBOND® steel, incorporating Thermatech® technology, provides a new level of thermal protection for houses and commercial buildings constructed in Australia.
For more than 40 years, COLORBOND® steel has revolutionised Australian building design, transforming our homes and our workspaces along the way. Today, 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 roofing and walling colours. (Thermatech® technology is not available in the colour Night Sky® and is not available in COLORBOND® Stainless steel)
Thermatech® technology was first introduced to COLORBOND® steel standard roofing and walling colours in 2008. In 2013, six new colours were added to the standard COLORBOND® steel standard range, four new shades of grey – Basalt®, Wallaby™, Gully™ and Cove™ – a eucalypt green called Mangrove®, and a rich red called Terrain®. During the development of these new colours Thermatech® technology was incorporated as a standard feature.
More comfortable to live in
Combining COLORBOND® steel with Thermatech® technology with insulation will help your building remain comfortable all year round.
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.
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.
Thermatech® technology can be an effective way to reduce the energy load of your building in summer. 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 moderate to hot climates, COLORBOND® steel with Thermatech® technology can reduce annual cooling energy consumption by up to 20%, compared to roofing materials of similar colour with low solar reflectance. (Average reduction is about 5%: results will depend on level of insulation, building shape and function)
COLORBOND® steel with Thermatech® technology absorbs less heat from the sun, protecting your roof and its supporting structure from extremes in heat. As a result, the stresses placed on your roof and its materials are reduced and your roof lasts longer.
Even darker colours reflect more heat
It's widely known that lighter colours are better at reflecting heat. Now 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®)
