Sound absorbing impact resistant laminate
Sound absorbing impact resistant laminate comprising a sound absorption layer 101, a gas permeable layer 103 and an intermediate spacer layer 102 having an open structure defining pockets. The gas permeable layer secured in position under tension of 0.5 5 N. The gas permeable layer may be fabric comprising a natural fibre such as wool, or cotton, a synthetic fibre such as polypropylene, polyester, nylon, viscose or viscose rayon. The fabric may be woven or non-woven. The sound absorption layer may be foam based, which may be open celled, or fibrous, which may be mineral or textile fibres. The spacer layer may comprise a mesh, grid, lattice, net or web structure which may be formed of a textile fibre, cotton, steel wires or a synthetic fibre. The defined pockets may be air filled. The spacer layer may be rigid or semi-rigid to resist deformation. The laminate may comprise an edging 113 which may be a rigid or semi rigid plastic, aluminium, timber, steel or an alloy thereof. The laminate may be formed as a panel. Also included are claims for a building, wall, floor or roof structure comprising the laminate.
