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.
