UK/France: A project between the University of Bath, University of Brighton, UniLaSalle in Rouen and five other academic and non-academic partners, and funded under the Interreg VA France (Channel) England programme, is investigating the performance of a range of waste materials and bio-based co-products as alternative building insulation materials. Three different materials are being evaluated: wheat straw bales, rapeseed stalks (processed into bio-composite) and recycled duvets.
A research team at the University of Bath is testing and comparing the thermal performance of each of the insulation materials by constructing three identical prototype wall panels, each containing one of the materials. Their performances will be compared and contrasted with each other as well as against industry standard insulation used currently in most buildings. The panels are 150mm thick by 1.1m2 and fitted with 9mm plywood either side, similar to how insulation is commonly installed within buildings. Each panel contains a number of probes to measure relative humidity, interior and exterior temperature, and heat flux. The panels will undergo six weeks of consecutive testing in an environmental chamber at the University’s Building Research Park. There will be two tests – a steady state and a non-steady state temperature test.
“This is the first time these materials will have been tested in such a robust scientific way, allowing us to accurately assess their thermal performance against each other as well as against industry standard insulation,” said Shawn Platt, Research Associate in the University of Bath’s Department of Architecture & Civil Engineering.
