For producing the floor, a polyurethane reaction mixture is sprayed onto a base (1) in order to form a polyurethane foam layer (2), and a covering floor (3, 4) is subsequently placed on this polyurethane foam layer (2). Unlike the existing methods, a softer polyurethane foam layer is sprayed in such a way that not only heat insulation, but also sound insulation is obtained. The hardness H of the foam layer, measured in accordance with NBN EN 826 at a compression of 10%, more particularly ranges between 5 and 80 kPa. As a function of said hardness, the foam layer is laid in a thickness in cm ranging between 1.5 x H/16 and 8.0 x H/16. <IMAGE> |
