Definitions
- the present invention relates to a preformed panel for heat and sound insulation of buildings and structures, such as walls, ceilings and/or floors.
- Materials of mineral origin are, for example, rock wool, glass wool, expanded clay and pumice.
- Materials of natural, vegetable or animal origin are, for example, various types of wood, cellulose, hemp, coconut, jute, reed, cork and lambswool.
- materials of synthetic origin are, for example, expanded polyurethane foam, expanded or extruded polystyrene, and synthetic fibres, such as polyester fibres, polypropylene fibres, polyamide or polyactide fibres and acrylic fibres, modacrylic and aramid (para-aramid and meta-aramid) fibres.
- the abovementioned materials are present commercially in the form of rigid and semi-rigid panels or in the form of loose material, in bead or fibre form, or in the form of matting.
- semi-rigid panels or matting of rock wool or glass wool rigid panels of cork, polystyrene, cork shavings, polyester fibres or polyamide fibres, and matting made of polyester or other synthetic materials.
- Panels made of natural insulants such as wool, wood or cork, ensure both good heat and good sound insulation and do not contain harmful substances, as, instead, is the case with insulants made of mineral fibres. They are, however, prone to deterioration with time and have a fairly high cost.
- Mineral insulating materials such as glass wool and rock wool, although they are fairly inexpensive and have good heat and sound insulating properties due to their fine-hair macroscopic structure which dampens noise and ensures heat insulation by trapping of large amounts of air, have the drawback that they are irritants when they make contact with the skin and require a moisture-proof barrier in order to prevent degradation which reduces the heat-insulating properties.
- Insulating materials of synthetic origin such as polystyrene, although excellent from the point of view of heat insulation, have the defect that they have a low biodegradability as waste material.
- Expanded polyurethane is an excellent material, but involves risks when applied using the spraying technique, and has higher costs than other products of synthetic origin.
- Polyurethane is also used in embossed panels which are characterized by the presence of air chambers which help increase the heat insulation and sound insulation.
- the patent application published under number US 2001/0012812 describes a panel which includes two layers comprising a plurality of cells with a frusto-pyramidal shape which are arranged facing and connected together and two covering layers which close and seal the cavities of the respective plurality of cells.
- the patent US 4,631,221 describes a panel which includes two external covering layers which enclose a shaped layer comprising a plurality of wells.
- the shaped layer is made of fabric, preferably knitted fabric, impregnated with a thermosetting resin.
- the panels described according to the prior art do not satisfy the criteria of lightness, low cost and suitability for recycling which are required nowadays for preformed panels used for the heat and sound insulation of buildings.
- the present invention relates to a preformed panel for heat and sound insulation of buildings and structures, such as walls, ceilings and/or floors, comprising a layer of non-woven fabric, preferably comprising polyester fibres, provided with a plurality of cells.
- the preformed panel according to the present invention preferably comprises, on at least one of the surfaces of the layer of non-woven fabric, preferably on both of them, a rigid covering layer which closes and seals the cells of the preformed panel.
- the Applicant has surprisingly found that the preformed panel according to the present invention is able to overcome the drawbacks mentioned above in connection with the conventional panels used for heat and sound insulation.
- the Applicant has found that, with use of the preformed panel according to the present invention, it is possible to reduce the thickness and weight of the panel, owing to the more efficient heat and sound insulation.
- the Applicant has also found that, with use of the preformed panel according to the present invention, it is possible to improve and simplify installation owing to the greater lightness and rigidity of the panel itself.
- the Applicant has found that, with use of the preformed panel according to the present invention, it is possible to reduce the overall cost of the heat and sound insulation compared to conventional insulation systems since the cost of installation and finishing is reduced.
- the Applicant has also found that the preformed panel according to the present invention offers advantages also from an environmental and ecological point of view, being preferably made of recycling material, in particular fibres of recycled polyester, and in turn being able to be easily recycled.

- the cells 2 have a depth of between 5 mm and 400 mm, preferably between 10 mm and 300 mm, and more preferably between 20 mm and 200 mm.
- the number of cells 2 present in a panel 1 depends on the size of the cells and the panel 1 itself. Generally, the number and the dimensions of the cells 2 are such as to cover a surface, viewed from above as in Figure 1 , greater than 50%, preferably greater than 70%, of the total surface, viewed from above as in Figure 1 , of the panel 1.
- the form and dimensions of the cells 2 are uniform in each panel 1, but it is possible to envisage panels comprising cells 2 of variable shape and size, i.e. with shapes and sizes different from each other, for example, large-size spherical shaped cells alternating with small-size cylindrical shaped cells.
