Building insulation materials can be installed within or either side of the buildings structure. At Integra we offer products that provide a good, better best approach to selecting insulation for walls, floors and roof to reduce heat transfer. The selection depends on the balance between condensation and fire requirements. The best solutions may not be the most thermally efficient but one that meets the needs of the client. Radiant barrier are rubbish as insulation. The product so far cannot provide testing to validate the claims and customer experience has not provided energy efficient designs. In Australia, for the major population centres like Sydney and Melbourne condensation risk has lead to rectification of new buildings due to condensation and mould forming on the cold side of glassfibre insulation.
