A roof made from COLORBOND® steel can make a valuable contribution to the overall thermal efficiency of your home, which is good news for your hip pocket and the environment.
Sustainable design is all about designing and building homes that have a reduced impact on the environment.
That means, in part, using long life materials that are recyclable and low maintenance.
COLORBOND® steel falls into that category, which is why it's recognised as a key component of 'green' housing and features on so many award winning, environmentally friendly houses.
Using thermally efficient roofing materials like COLORBOND® steel can help you reduce your cooling and heating costs. In summer, a lightweight insulated roof made from COLORBOND® steel causes less heat to be radiated into your home at night. That's because steel has a low thermal mass, so it cools down fast once the sun is off it.
In winter the same steel roof, properly insulated, helps keep the heat inside. The choice of colour can also influence thermal performance. Lighter colours, in particular, radiate less heat during summer.
COLORBOND® steel now includes Thermatech® technology, enhancing its position as the energy efficient roofing material. For more information view our page on Thermatech® technology.
The choice of roofing material is only one factor to consider when designing a 'green' home.
Both the Building Code of Australia (BCA) and the New South Wales Building and Sustainability Index (BASIX) classify colours into light and dark according to their solar absorption rates.
