Embodiments of a leno weave mesh of the present invention generally include a plurality of high-temperature weft yarns, high-temperature warp yarns, and low melting point warp yarns; wherein each low melting point warp yarn is intertwined with a high-temperature warp yarn, each intertwined pair of warp yarns is positioned such that the low melting point warp yarn and high-temperature warp yarn are disposed alternatingly on either side of the woven mesh at intersections of the weft and warp yarns, and the woven mesh is heated whereby the surfaces of the low melting point warp yarns adhere to the surface of the high-temperature warp yarns and said high-temperature weft yarns at contact points there between. An intumescent coating system employing embodiments of the mesh, and a method of providing thermal protection to a substrate utilizing the intumescent coating system, are also provided.

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.

An object of the present invention is to provide a sound insulating sheet member that has high sound-insulating performance which exceeds mass law while being relatively light weight, that is highly flexible in design, excellent in versatility, and easy to manufacture so that productivity and economic efficiency can be improved, and a sound insulating structural body or the like using the same. The object thereof is achieved by using a sound insulating sheet member comprising at least a sheet having rubber elasticity and a plurality of resonant portions, wherein the resonant portions are provided in contact with a sheet surface of the sheet, each of the resonant portions including a base part and a weight part, and the weight part being supported by the base part and having a larger mass than the base part.

A lumber use designation system includes a building construction plan that shows the layout, wall thickness, wall height, ceiling angles, etc., of a structure, which are color coded from a series of color codes each corresponding to a preselected, standard board size and length of lumber that should be selected for constructing a particular portion of the structure. The system includes a supply of lumber boards marked with a color code correlating to the color code found on the construction plans. The lumber boards may be imprinted by an ink spray head. A method of installing lumber during the construction of a structure is disclosed.

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 composite material, a method for the production thereof, and a fire protection element containing the composite material can be used for the protection of passage openings in components in the event of fire, such as building parts, through which conduits are guided. The composite material can also be used as a fire protection element for sealing passage openings and/or joints in components.

This disclosure relates to a wall cladding, including: a supporting structure; a safety supporting structure; wall cladding elements; at least one structure attachment element made of plastic; at least one cladding attachment element per wall cladding element, where the cladding attachment element forms part of the wall cladding element or is attached thereto and is couplable to the structure attachment element; at least one safety attachment element per wall cladding element, where the safety attachment element forms part of the wall cladding element or is attached thereto; and at least one safety element per wall cladding element, where the safety element is designed to be fire-resistant, is attachable to the safety supporting structure, and is attachable to the safety attachment element.

There is provided a ceiling panel for a pod room. The ceiling panel comprises one or more cover components movable between an open configuration and a closed configuration; and an actuation mechanism configured to move the one or more cover components from the closed configuration to the open configuration in response to a trigger. The ceiling panel may provide a specified percentage open area in the open configuration. The ceiling panel may be adapted to acoustically insulate the pod room in the closed configuration.
