Austech External Building Products recommends Foamular XPS insulation for concrete roofs to address specific problems related to energy efficiency and comfort.
The concrete in concrete roofs acts as a conductor with heat passing through the concrete and also getting stored in its thermal mass. As a result, apartments on the top floor can create an uncomfortable environment for occupants as well as reduce energy efficiency.
However, the twin problems of concrete roofs can be resolved by installing Foamular XPS insulation.
Foamular 300kpa 65mm insulation was recently fitted to the roof of the Newcastle Courthouse by NJD Corporation, a construction, maintenance and remedial building company delivering a diverse range of services to the construction industry.
Designed to provide the largest and most technologically advanced NSW court complex outside of Sydney, the seven-storey, 12,000-square-metre Newcastle Courthouse will have 10 state-of-the-art courtrooms and two tribunal rooms to host Local, District and Supreme Court hearings.
The high performance insulation product, Foamular closed cell extruded polystyrene has been installed on the topside of the concrete roof to increase the comfort factor, reduce energy demands and also protect the expensive waterproofing membrane. Foamular has a 50+ year lifecycle and will continue to reduce energy demand over its lifetime. The minimum compressive strength of 300kpa allows Foamular XPS to support high loads.
