Abstract: For removing water condensed on the outer surface of a tube (10) which is insulated by means of an insultating assembly (12), a plug (30) is arranged extending through the insulating assembly. The plug comprises a conduit component (32) in which a capillary suction material (36) is enclosed. The material (36) communicates with an evaporator foil (38) circumferentially encircling the outer cylindrical surface of the insulating assembly (12). The capillary suction material (36) may be substituted by a foil of a capillary suction material or a hygroscopic paint.

Abstract: Method for insulating of roofs by which insulating slabs of mineral wool with fibres bonded at their intersections are placed on top of the water-impermeable membrane on the roof. The insulating slabs on their surface facing the water-impermeable membrane are provided with a vapor-impermeable foil.

Abstract: A composite load-bearing structural column utilizable as studding in the exterior walls of wooden frame buildings includes a pair of vertically extending parallel and spaced wooden stud elements. Substantially completely filling the space between the stud elements there is positioned a core of mineral fibre felt having the fibres thereof bonded together with a resinous material. The core is joined adhesively on the respective opposite faces thereof to corresponding abutting faces of the stud elements. The core has a depth at least as great as the combined depths of the stud elements.
