Abstract: This invention relates to a complex sound-insulating material comprising a first lower sub-assembly, itself comprising at least one layer of a bituminous product, and a second upper layer which covers said first sub-assembly. The first sub-assembly comprises a first upper layer, a first intermediate layer and a first lower layer, whilst a) each of the first upper and lower layers is made of oxidized bitumen reinforced with first fibers and has a surface mass of between 500 and 1000 g/m.sup.2 ; b) the first intermediate layer is made of an organic binding agent, such as a bitumen, and by second fibers which are embedded in said binding agent and are in a non-woven form; and c) the second upper layer is made of an elastic foam.One application of the invention is the production of a sound-insulated tiled flooring.

Abstract: This invention relates to a profiled strip particularly adapted to compensate the relative displacements of surface coverings with respect to the walls, wherein said profiled strip comprises: a generally flat sole plate; two principal limbs which extend from the sole plate, perpendicularly thereto; a bridge for connecting the ends of said principal limbs and two secondary limbs which extend substantially parallel to the sole plate, from the principal limb most remote from the free edge of the sole plate, these two secondary limbs having substantially equal widths; the sole plate and the principal limbs being made of a hard, semi-rigid material, and the connecting bridge being made of a supple material.One application of the invention is production of the zone of connection between a tiled floor and partition.

Abstract: This invention relates to a material for use in the production of a flooring in a building construction.According to the invention, this material comprises an upper layer, an intermediate layer and a lower layer, while: a) each of the upper and lower layers is made of oxidized bitumen reinforced with first fibers and has a surface mass of between 500 and 1000 g/m.sup.2 ; and b) the intermediate layer is made of an organic binding agent, such as a bitumen, and by second fibers, which are embedded in said binding agent and are in non-woven form.One application is constituted by the laying of a tiling not subject to the development of cracks.
