A liner for lining an aperture in sheet material such as plasterboard, the liner having an annular ring defining a hole having a smaller diameter than an aperture to be lined, a slot extending from the inner periphery of the hole to the outer periphery of the ring, so sized and shaped as to allow the liner to be passed from one side of the aperture to the other. A lip may be provided around the hole. The lip may have deformable tabs for gripping the inside of the aperture. The liner may be of flame resistant fibreboard. Resiliently-deformable and size adjustable liners are also provided. Also provided are methods of repairing, reinforcing or re-sizing apertures in sheet materials.
