Abstract: A floor underlayment for positioning and mounting a heating element beneath a finished floor is described. The floor underlayment comprises a plurality of studs extending upwardly from a base layer, where the outer wall of the studs forms an acute angle with the base layer and a smooth inner wall defines a cavity within each stud. Mounting corridors formed by rows or columns of adjacent studs are sized to receive and retain a heating element.

Abstract: The invention relates to a backing layer (10; 20) of a multilayered insulating panel (100) for building constructions. Said backing layer comprises:—a gas-tight reinforcement layer (1) comprising a first surface (F1) and an opposite second surface (F2);—a fire-resistant layer (2) for example in expandable material, operatively associated to the first surface (F1) of the reinforcement layer (1).

Abstract: The invention relates to a multilayer thermal insulation panel for construction (100) and manufacturing method thereof. Such panel comprises: —a main layer (1) in thermally insulating material which comprises a first surface (10) and a second surface (20); —a first backing layer (2) of the main layer connected to the main layer along the first surface (10); a second backing layer (5) of the main layer connected to the main layer along the second surface (20). At least one of such first (2) and second (5) backing layers comprises: —a reinforcement layer (3) in fibrous material, a fire-resistant (4) and thermally insulating layer, —a cladding layer (6) of the reinforcement layer (3); —a binding layer (7) positioned on a surface (8) of the fire-resistant layer (4) in such a way that the fire-resistant layer is sandwiched between the cladding layer (6) and the binding layer. The panel is characterised in that the binding layer (7) is manufactured by means of.
