An improved fire blanket for use in expansion joints of buildings to retard the movement of fire and smoke. The invention permits movement of the joint without damaging or otherwise compromising the fire-retardant properties of the barrier. This movement may occur when the width of the joint changes due to expansion or contraction of the joint or when one side of the joint moves relative to the other along the length, or longitudinal axis, of the joint. The expansion and contraction introduce compressive and tensile loads and the relative movement along the length of the joint introduces shear loads. The invention prevents such compressive/tensile and shear loads from being introduced into the assembly and impacting its fire-retardant capabilities.

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.

The present is a containment enclosure made from refractory material. The enclosure contains a plurality of panels and a plurality of columns made from refractory material. The enclosure has an interior portion and an exterior portion, and wherein the enclosure contains the effects of extreme fire as well as contains the effects of explosions.

System for assisting in reducing the spread of fire between adjacent rooms in a building proximate to the ceiling thereof includes an elongated header track, at least one elongated filler constructed at least partially of compressible or elastic material and at least one fire-blocker constructed at least partially of fire retarding material.

A smoke barrier system includes a bracket, a glass panel and a fastener. The glass panel defines a hole. The fastener is equipped to fasten the bracket to the hole of the glass panel. The bracket is fixed to a supporting construction on which the smoke barrier system is installed. The smoke barrier system also includes a first washer, wherein the washer is arranged between the fastener and the glass panel. The washer is an intumescent washer that expands under thermal influence of a fire, hot smoke and/or hot gas. Under thermal influence, the washer can form a thermally insulating layer. Furthermore, under thermal influence the intumescent washer can build up additional pressure between the fastener and the glass panel.

The invention is a below grade waterproofing and methane barrier sheet membrane with an aluminum facer and a method of making and using same, and more particularly the invention is directed to a dual layer system comprising of at least one bituminous moisture or waterproofing barrier sheet membrane with an aluminum facer or an aluminum layer that when combined is also a methane gas barrier, and is UV stable, that is used in construction of a building, and placed under, or around a foundation of a building or a dwelling or on its below grade retaining walls. Optionally, a liner and/or a drainage protection media can also be used with the inventive dual layer system.

A polyisocyanurate foam insulation product includes polyisocyanurate foam produced from reacting an isocyanate and a polyol blend having a functionality of at least 2.2. The isocyanate and the polyol blend are reacted so that the polyisocyanurate foam has an isocyanate index equivalent with or greater than 300. The polyisocyanurate foam includes a fire retardant and includes between 0.02 and 0.45 weight percent of a zinc salt compound. The foam insulation board exhibits a flame spread of no greater than 25 and a smoke index of no greater than 50 when exposed to flame conditions in accordance with an ASTM E-84 test.

A line penetration for routing a line through a building part. The line penetration includes a first lamellar element with a hollow-cylindrical first base part for receiving the line in a straight-through line opening, and with first circumferential lamellas, which extend outwardly transverse to an axial direction of the first base part; a second lamellar element with a hollow-cylindrical second base part for arrangement in a passage opening of the building part, and with second circumferential lamellas, which extend inwardly transverse to an axial direction of the line opening, where the first and second lamellas mesh with one another in the manner of a comb, so that the side faces of the lamellas are impermeable to gas and bear slidingly on one another.
