Definitions

  • the invention relates to the field of furnishing panels.
  • Known and already used are furnishing panels with through holes consisting of a high or medium density central layer of wood fibre or wood pulp or the like and a veneer on the two larger surfaces.
  • One type of such panels is marketed by Locatelli Laminati SaS di Locatelli Uberto & C. These panels have a thickness of 6 mm or less. They are generally used for decorative purposes, for cupboard doors, room dividers and generally where it is wished to allow a certain passage of light and air and a partial vision.
  • An object in the building field is to obtain increasingly good sound absorbing effects with a relatively small bulk and low weight.
  • the invention solves the problem posed above and provides excellent sound absorption with a little thickness and a good aesthetic appearance.
  • the new panel comprises a core layer of compressed wood material coated on each side with wood veneer, this layer having through holes, and a layer of sound absorbent material, comprising a sheet of non-woven fabric, glued to a veneered surface.
  • the through holes can be square, rectangular or round in shape, preferably with a void to solid ratio of not less than 15%.
  • the invention achieves the above mentioned objects.
  • the panel of the invention is indicated as a whole with reference numeral 10. It comprises a layer 12 of wood or wood type material and a layer 14 of sound absorbent material.
  • the layer of wood material 12 comprises a core 16 of sound compact wood fibre or the like, that is to say, with a density from 500 to 1100 kg/m3 and two sheets of veneer on the larger surfaces, indicated respectively with 18 and 20.
  • the layer 12 of wood material has an arrangement of through holes 22, in this case a regular arrangement of square holes with a void/solid ratio of about 25%. Obviously the shape of the holes can be different, for example round, polygonal, etc.
  • the holes in the layer 12 are covered or closed, on one side of the wood layer, by the sheet of sound absorbent material 14.
  • the layer of wood is preferably 0.5 to 1 mm thick.
  • the sound absorbent material 14 can be a commercially available sheet material, for example a non-woven fabric in polyester, and/or cellulose, and/or polypropylene, etc.
  • a further sheet or plate 24 of sound absorbent material (Figure 3) can be applied to the panel to improve its performance.
  • the sheet 14 and the sheet 24 can be applied in any known manner, for example by gluing.
  • the sound absorbent panel thus created has particularly high levels of sound absorption, superior to that which might logically be expected from a combination of the two basic elements (panel with holes and sheet) and superior to those that can be obtained with known panels of the same thickness.
