Definitions

  • the present invention relates to thermal insulating panels comprising a layer of cellular plastic material ensuring the thermal insulation of constructions.
  • thermal insulation panels of this kind comprising a layer of expanded polystyrene or polyurethane foam, have advantageous thermal resistance characteristics, due to their low coefficient of thermal conductivity.
  • they have a dynamic elastic modulus E of between 2 and 4 MPa depending on their density.
  • the double wall behaves acoustically substantially like a single wall.
  • the isolation of the doubled wall increases as one moves away from the resonant frequency.
  • the presence of insulating complexes with layers of expanded polystyrene can even significantly reduce the overall acoustic insulation of the support wall on which they are placed (drop of 5 to 6 dB (A)).
  • a 14 cm thick concrete wall has an acoustic reduction index R of 52 dB (A).
  • This same wall coated with expanded polystyrene sheets 60 mm thick and gypsum plasterboard 10 mm thick has a sound reduction index R of 50 dB (A).
  • a 22 cm thick reinforced concrete floor has an acoustic reduction index R of 61 db (A), while this same floor, coated on the underside with a sandwich panel made of a expanded polystyrene 80 mm thick and two fibragglo facing 20 mm thick, has an acoustic reduction index R of 55 to 58 dB (A) depending on the nature of the polystyrene and the degree of elasticity.
  • the object of the invention is to avoid these drawbacks.
  • the invention relates to an insulating panel comprising at least one layer of cellular plastic foam, characterized in that said layer has a multiplicity of elongated slots with a chevron profile extending parallel to each other and parallel to the faces of the layer, alternately from the two faces of the layer.
  • the foam layer is in particular a sheet of expanded polystyrene with a thickness of the order of 8 to 20 cm and a format varying from 1.20 by 3.00 m to 0.50 m by 1.00 m.
  • the expanded polystyrene can be elasticized according to the traditional technique mentioned above, then cut and machined to the desired shape.
  • the layer obtained is associated by bonding with one or two fibbraglo facings which may have a thickness of the order of 20 mm.
  • this same layer of expanded polystyrene is associated with one or two smooth facings, with a thickness of 1 to 20 mm approximately, for example one or two gypsum plasterboards of 9.5 mm, 12, 5 mm or 15 mm thick approximately.
  • the dynamic elastic modulus E of the sandwich or composite panel in the thickness direction is of the order of 0.2 to 0.3 MPa.
  • the layer of elastic material working in shear dissipates much more energy. It follows that the vibration level of the wall under the action of a sound field is reduced by this process.
  • the reduction in the vibration level is such that the resonant frequency is no longer marked. Since this resonance frequency is no longer marked, it follows that there is no longer an isolation drop at this frequency and, as a result, the overall isolation of the wall is no longer reduced.
  • the layer of expanded polystyrene, cut and machined remains as it is, without additional facings.
  • Such a monolayer panel has substantially the same modulus of elasticity as the composite panels described above in the direction of the thickness.
  • it has a dynamic elastic modulus in the direction parallel to its faces and perpendicular to the length of the slots of the order of 0.05 to 0.2 MPa and can be compressed elastically in this same direction in a portion a few centimeters per meter, which can represent several millimeters to several centimeters depending on the format of the panel.
  • the invention also relates to a method of insulating lining of a wall by a panel as defined above comprising at least one facing, in which one sticks the facing on the wall, the facing preventing the adhesive from reaching the slots of the foam layer.
  • the panel illustrated in FIG. 3 consists of a sheet of expanded polystyrene 1 previously elasticized according to a traditional process, in which, in a regular pitch 4, cuts or slots 2 and 3 with a herringbone profile have been produced, alternately and respectively from the lower face and the upper face of the plate. These slots extend along the length of the plate and open at its two ends. They can be made using a heated wire with a width of about 1 mm.
  • One of the faces of the expanded polystyrene plate has grooves 5, each of which joins two consecutive slots 3.
  • the chevron-shaped cutouts and the grooves could also be made across the width of the plate.
  • the panel according to the invention represented in FIG. 1 is obtained (FIG. 4) by association of the expanded polystyrene plate 1 of FIG. 3 with fibragglo facing 6 and 7 fixed on the expanded polystyrene plate by gluing.
  • the panel according to the invention represented in the held figure (FIG. 5) by association of an expanded polystyrene plate 1 with a facing of cardboard plasterboard 8 fixed by gluing. This plate differs from that of FIG. 3 by the absence of the grooves 5.
  • the panels, according to FIG. 1, are generally used as insulated lost formwork for concrete floors as shown in section in FIG. 7 in fibragglo. It is associated with a solid concrete slab 12.
  • the panels, according to Figure 2 are mainly used as insulating linings of concrete or masonry walls, as shown in section in Figure 8.
  • This assembly also functions as a particular "mass-spring-mass" system and allows to improve the acoustic insulation R of the wall 14 alone, uncoated.
  • the panels according to FIG. 6 are generally used to insulate sloping roofs, as illustrated in FIG. 9.
  • the panel according to the invention in expanded polystyrene 1 is shown there in section, placed between two rafters 15 and 16 of the roof. To put it in place, it was compressed according to effort 10.
  • the elasticity of the panel allows it to be held in place between the rafters 15 and 16.
  • the panels according to the invention can in particular be used when it is sought to achieve thermal insulation of a wall and when it is desired simultaneously to improve its sound reduction index.
  • Particularly interesting applications can be envisaged for making separating floors between underground car parks and housing, or separating housing walls.
  • the panels with facing may or may not have grooves.
  • the panels according to the invention can optionally comprise one or two facings, whether these are made of fibragglo or of another type.
  • the panels according to the invention are applicable to the insulating lining of the walls as illustrated in FIG. 8, it has been found in this case that the adhesive partially penetrates into the slots and, if necessary, into the grooves of the layer. foam, reducing their effectiveness. This results in an increase in the dynamic elastic modulus and a deterioration in the acoustic characteristics of the lined wall.
  • This method uses a panel as described above and which comprises, at least on the face of the layer of foam facing the wall to be lined, a facing preventing the adhesive from reaching the slots.
  • This facing is interposed between the foam layer 1 and the adhesive pads 13 of FIG. 8.
  • the adhesive cannot therefore penetrate into the slots and, if necessary, into the grooves and the acoustic characteristics of the panel are preserved.
  • Such an air-permeable facing may consist of a glass veil, preferably with a thickness of between 1 and 2 mm approximately.
  • a light and economical facing can be provided by a second layer of plastic foam, for example of elasticized expanded polystyrene, the face of which faces the wall is free of cuts.
  • a layer can have a thickness of between 5 and 10 mm approximately.
  • the face of the layer of foam turned away from the wall can also be covered with a facing, for example made of cardboard plaster, such as that indicated at 8 in FIG. 8.
