About to do some insulation work and trying to figure out if it would be worth pumping the cavity walls with beads ?
Construction method is twin leaf brick/block work; 425mm and 300mm outer leaf, 225mm inner leaf block and 300mm block, with probably 100mm cavity and 60mm expanded polystyrene insulation .
