A profile element is useful for sealing building-structure joints, especially for sealing against sound and smoke and optionally against fire. An apparatus is useful for manufacturing such profile element and to the use of the profile element manufactured according to the invention for the acoustic, smokeproof and/or fireproof sealing of connecting joints in drywalls, especially of expansion joints.

A fire-rated angle piece and wall assemblies or other assemblies that incorporate the fire-rated angle piece, in which the angle piece can include an intumescent or other fire-resistant material strip. The angle can be attached adjacent to a corner of a framing member, such as metal tracks, headers, header tracks, sill plates, bottom tracks, metal studs, wood studs or wall partitions, and placed between the framing member and a wall board member at a perimeter of a wall assembly to create a fire block arrangement. A fire spray material can be applied over a portion of the angle piece.

An elongate component for placement in a wall gap and a wall incorporating such a component. The component includes a wall-face leg configured to extend along a face of a wallboard and a wall-end leg configured to extend along an end of the wallboard. The wall-end leg is oriented perpendicular to the wall-face leg. The component further includes a flexible gap portion configured to be positioned within and extend along the wall gap. The gap portion is located on an opposite side of the wall-end leg relative to the wall-face leg. A blocking element is located in a space defined by the wall-end leg and the gap portion. The blocking element is configured to block fire and/or sound within the wall gap. At least a portion of the flexible gap portion is located on an exterior side of the blocking element.

Described is a construction and parts of the construction for effectively thermally and acoustically insulating and sealing of a head of wall joint within a building construction having a metal deck construction defined by a head of a wall and a metal fluted deck comprising one or more flutes, wherein the head of wall is defined by a head of wall track including vertical studs and a dry wall affixed thereto, and wherein the head of wall track is installed parallel to the flute to the underside of the metal fluted deck defining a head of wall joint extending between the top edge of the dry wall and the underside of the metal fluted deck.

A method of improving at least one property of a partition wall, the method comprising positioning an insert panel inside the partition wall wherein the insert panel comprises a mineral fibre board coated on at least one side with a polymer forming composition comprising a fire retardant compound.

A fire-rated receiver channel includes at least one intumescent or other fire-resistant material strip. The receiver channel can nest with a framing member, such as metal tracks, headers, header tracks, sill plates, bottom tracks, metal studs, wood studs or wall partitions, and placed at a perimeter of a wall assembly to create a fire block arrangement. In other arrangements, a track assembly includes two nested tracks, an inner track and outer track. The assembly is designed so that the outside width of the outer track is equal to or less than the outside width of the inner track to present a substantially flush external surface for attachment of exterior sheathing elements when the assembly is used in an external wall.

A window wall assembly includes a floor slab, a first window with a bottom sill positioned atop the floor slab and a second window with a top sill positioned at a lower surface of the floor slab. A panel extends between the first and second windows such that a void is defined between the panel and the floor slab. A fire-retardant gasket is positioned within the void and in sealing contact with the floor slab and the bottom sill.

Robust multi-purpose, multi-layer, building construction tapes and building construction framing members and related wall assemblies are disclosed that comprise a sheet metal framing member (all profiles) in combination with a new and more robust type of multi-layer building construction tape for fire safety and sound reduction. The multi-layer building construction tape comprises a flexible thermal barrier layer attached to (1) a flexible intumescent material layer having a lesser width (thereby enabling flex-lock rollover) and/or (2) a resilient unfoamed cross-linked polyethylene layer. In combination, the thermal barrier layer is on a surface of the sheet metal framing member, whereas the thermal barrier layer is attached to the intumescent layer or polyethylene layer (as the case may be) such that the thermal barrier layer is between the sheet metal framing member and the intumescent layer or the polyethylene layer. The multi-layer building construction tapes disclosed herein slow and impede the spread of fire and smoke (during a fire) and also reduces sound transmission between adjacent rooms in a building.

A fire-rated component for a linear gap between a wall assembly and an adjacent structure. The component includes an elongate metal profile and a fire-rated board member. The elongate metal profile has a vertical leg, an upper leg and a lower leg. The upper leg extends in a first direction from an upper edge of the vertical leg. The lower leg extends in the first direction from a lower edge of the vertical leg. The fire-rated board member is positioned within a space defined by the vertical leg, the upper leg and the lower leg.

A joint-sealing element is useful for fireproof sealing of building-structure joints, especially for fireproof sealing of a joint between a first building part and a second building part, with a carrier element and a sealing profile disposed on this carrier element, wherein the disposed sealing profile contains an intumescent material.
