Composite material for heat and/or sound insulation and absorption. This material is advantageously made up of a sheet 10 of a heat and/or sound insulating material consisting, in fact, of a first layer of synthetic foam 10a and of a second layer 10b of synthetic foam, these two layers being separated by a heavy mass 12 made up of a PVC sheet. A grid 11 is integrally attached to the free face of the layer 10a. The free face of the layer 10b is coated with an adhesive film 13 enabling the material to be placed on a panel of sheet metal 14 or the like. This material is advantageously employed for the construction of paint booths, mobile workshops, ventilation and air treatment chambers, white rooms or sterile chambers or even extension offices and the like. <IMAGE> |
