Definitions

  • This invention relates to a thermally insulating and sound absorbent panel.
  • Panels consisting of a layer of mineral wool (glass wool or rock wool) covered on one or both sides with a thin containing sheet of paper, cardboard, plastics, metal etc.
  • these panels When used in particular for forming ventilation ducts, these panels are generally covered externally with an aluminium sheet and lined internally with glass cloth or an aluminium sheet.
  • the duct formed with such panels has a considerable tendency to form dust clouds consisting of glass fibres which have been separated by the air flow and entrained by it along the duct.
  • the present invention is further clarified with reference to the enclosed sheet of drawing showing in partially perspective view a panel according to the invention.
  • the panel according to the invention used in particular for forming a ventilation duct, comprises an inner layer 2 of glass wool or rock wool, covered on both sides with two aluminium sheets 4, 6 applied by conventional methods.
  • the aluminium sheet 4 which lies on the inside of the formed ventilation duct, has been previously subjected to an embossing process but has a thickness of about 40 ⁇ , ie a thickness less than the minimum thickness necessary for embossing. In this manner it is subjected by the embossing rollers to a series of stretchings and microlacerations extending over its entire surface.
  • microlacerations are such that they are sufficient to interrupt the surface continuity of the sheet and hence give the resultant panel sufficient sound absorption characteristics, but at the same time are insufficient to allow the fibres of the mineral wool layer to pass and hence lead to undesirable dust formation.
  • microlacerations can in fact be so small that they can be seen in the aluminium sheet only by transparency, and hence are invisible in the formed panel, so eliminating the uncertainty which can sometimes make such a product poorly desirable.
  • the panel can also be advantageously used interposed between two plasterboards to insulate false ceilings, and in other acoustic and/or thermal applications.
