The sealing tape for sealing a joint comprises two foam strips of flexible foam, which are not formed as integral parts of each other, and which are arranged next to each other in the functional direction of the sealing tape. A film strip is arranged between the foam strips and is bonded to both foam strips. Adhesion sites between the film strips and the first foam strip are arranged only in an upper area of the first foam strip and in a lower area of the first foam strip, whereas, in an intermediate area between the upper area and the lower area of the first foam strip, the film strip is not adhesively bonded to the first foam strip.

A fire-stopping material for use in sandwich panels is provided, wherein the fire-stopping material comprises a resilient, porous material at least partially impregnated with an intumescent agent. A panel for an internal wall and an internal wall are also provided, comprising the fire-stopping material disposed between two substantially parallel boards, such as plaster boards. A method of providing a service penetration through an internal wall is also provided.

A fire-stopping material in a panel for an interior building wall is provided. The fire-stopping material includes a resilient, porous material at least partially impregnated with an intumescent agent.

The invention provides a fire-stopping product, an insulated building façade comprising a fire-stopping product, and a method of making a fire-stopping product. The fire-stopping product comprises a resilient, porous material at least partially impregnated with an intumescent agent and held in compression by a releasable restraint. When exposed to hot gases from a fire, the restraint yields to release the resilient, porous material in an initial expansion, thereby exposing the intumescent agent to the hot gases and allowing rapid intumescence to occur. When implemented in a ventilated building façade, the fire-stopping product is able to close an air gap in a short amount of time.

A sealing tape roll comprises a sealing tape of flexible, compressible foam with a plurality of interior barrier layers, wherein the sealing tape is wound up into the sealing tape roll around an axis extending transversely to a longitudinal direction of the sealing tape in such a way that side surfaces of the sealing tape form end surfaces of the sealing tape roll. The sealing tape comprises a plurality of sealing tape sections, which, in an unwound state of the sealing tape, are arranged in a row in the longitudinal direction, wherein a barrier layer of the plurality of barrier layers is arranged between each pair of adjacent sealing tape sections of the plurality of sealing tape sections. The plurality of barrier layers extend over at least 50% of a width of the sealing tape roll between the opposite end surfaces of the sealing tape roll.

The sealing tape comprises at least one base body of flexible foam capable of recovery after compression. In the area of the bottom surface of the sealing tape, an adhesive layer for bonding to a frame profile of a window or door is arranged. The sealing tape comprises a continuous barrier structure for reducing the permeability to the diffusion of water vapor and/or the permeability to air in the functional direction of the sealing tape, wherein the barrier structure extends from the top surface to the bottom surface and also extends over an area of the top surface. The barrier structure comprises, at least in the area of the top surface, a closed-cell flexible foam or consists of closed-cell flexible foam. The barrier structure, at least in the area of the top surface of the sealing tape, has a thickness of between 10 μm and 5 mm.

In the area of the bottom surface of the sealing tape, an adhesive layer for bonding to a frame profile of a window or door is arranged. The sealing tape comprises a continuous barrier structure for reducing the permeability to the diffusion of water vapor and/or the permeability to air in the functional direction of the sealing tape, which barrier structure begins from at least one side surface and extends along the top surface to an area between the side surfaces, from where it then proceeds from the top surface to the bottom surface, and finally extends along a bottom surface of the at least one base body from the area between the side surfaces to at least one side surface.

A method for producing a sealing tape with interior barrier layers, each of which extends between opposite end surfaces of the sealing tape, the method includes the steps of providing a first foam web; applying a first barrier layer to a first surface of the first foam web to form a laminated foam web; introducing a plurality of first cuts into the top surface and a plurality of second cuts into a bottom surface of the laminated foam web in the transverse direction, the cuts being offset from each other in the longitudinal direction, to form strips arranged behind each other in a row; folding over the strips to produce a foam-barrier layer web, such that subsections of the top surface lie opposite each other and subsections of the bottom surface lie opposite each other; and forming a sealing tape roll from the foam-barrier layer web.
