The invention relates to a device for passing pipes or cables through an opening in a building. Said device comprises a sleeve-like housing that has an axial passage channel that is open at its opposite ends; bristles that are mounted on the walls of the passage channel in such a way that they are opposite each other and that are extended inwards in such a way that they mesh with one another in order to close the passage channel; and flexible strips of material that are mounted in the passage channel and that are coated with an intumescent material.

A ventilation duct for a fire rated ventilation duct wall penetration has one or more metal sheets forming said duct, wherein said metal sheet duct is covered on the outside by a heat insulating material, and said duct includes elongated stiffening members located on the outside of the duct and attached to said metal sheets. The stiffening members each comprises a metal profile and at least one non-combustible bar of inorganic material. The metal profile is fixed to the metal sheet of the duct and retains the non-combustible bar by at least partly encircling the bar.

Conduit through which at least one pipe or cable extends, wherein the conduit has an inner wall and is provided with a system for sealing in the conduit that is unoccupied by the at least one pipe or cable, wherein the system comprises: at least one rubber element for providing in the conduit a support-structure which is clamped-in between the inner wall and the at least one pipe or cable; and a sealant layer against the support-structure and for sealing off at least one end of the conduit between the inner wall and the at least one pipe or cable, wherein each rubber element is made of a fire-resistant vulcanized rubber of a thermally substantially non-expandable type, and wherein the sealant is made of a fire-resistant polymer which is vulcanizable at room temperature under exposure to humidity and which is also of the thermally substantially non-expandable type.

A feedthrough module for cables, cable bundles, cable trays, pipes, pipelines, empty pipes and/or combinations thereof contains hardwood, softwood or mixtures thereof and is intended for installation in a tested and/or approved wooden wall and/or wooden ceiling construction in buildings. The tested and/or approved wooden wall and/or wooden ceiling construction has an equal or lower burn rate than the feedthrough module. The feedthrough module has a cuboid body having edge lengths a, b, c, wherein c represents the edge length corresponding to the installation thickness (D) of the feedthrough module, and wherein the feedthrough module has a nominal burn rate of 0.7 mm/min or less.
