Description
To partly address the future sustainability of energy use in buildings, there is a program in Europe to retrofit domestic and commercial buildings with non-load bearing insulated re-cladding and over-cladding panels. Recent research work has shown that limited composite action is possible depending on the type of non-conductive shear connector and the stiffness of the insulation between the inner and outer wythes. This paper reports on the mix design development to develop high strength 20mm thick wythes and the manufacture of sandwich panels with five silicone-bonded layers of XPS insulation, making up a panel which is 220mm thick. These model panels are then tested in flexure using displacement control to establish the effectiveness of the composite action and post-cracking ductility of the panel in resisting loads.
