Abstract

A method for removing cavity wall insulation from a cavity wall comprising first and second wall leaves 12, 14 separated by a cavity space, the cavity space 16 being at least partially filled by cavity insulation material 30 comprises the steps of: forming an outlet aperture 54 in a first one of the leaves; injecting compressed air into the cavity at a number of spaced apart locations 42 located above the outlet aperture; and removing at least part of the cavity wall insulation via the outlet aperture 54, wherein the method further comprises the step of forming bands of empty space within the cavity by injecting the compressed air into the cavity via one or more apertures located at different heights, beginning at or towards the base of the wall, and moving upwards in stages.
