Abstract: Systems and methods of installing and retaining insulation relative to at least one of a mullion and a transom having a given width. The methods comprise: using a fastener to attach to a side surface of the mullion or transom a side plate of each of a plurality of spaced apart L-brackets, each said L-bracket having a first receiving slot formed in the side plate; positioning the insulation in a space adjacent to at least one of the mullion and the transom; and engaging with each L-bracket a clip having a pair of clip legs with a first of the pair of clip legs extending through the first receiving slot of the L-bracket and a second of the pair of clip legs penetrating into the insulation. At least one of the clip legs has a tapered free end.

Abstract: A sealing plug configured for sealing a passage of a curtain wall mullion. The passage has a maximum width and a length. The sealing plug includes a main body extending from a first surface to a second surface. The main body has a width at least as large as the passage maximum width and a length at least as large as the passage length. The main body is manufactured from a compressible foam. An intumescent layer is defined along at least one of the first and second surfaces.

Abstract: A firestopping apparatus including a housing defined by first and second housing members. Each housing member includes a width direction wall panel and a height direction wall panel. The width direction wall panel of the first housing member is configured to connect with the height direction wall panel of the second housing member and the width direction wall panel of the second housing member is configured to connect with the height direction wall panel of the first housing member to define an assembled housing with a through passage. Intumescent material is positioned along an inner surface of each wall panel. A compressible foam is positioned within the intumescent material and substantially closes off the through passage.

Abstract: 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.

At least one of the clip legs has a tapered free end.

Abstract: A curtain wall assembly including a curtain wall and a slab attached to the curtain wall with a gap therebetween. A fire rated bumper assembly is positioned in and seals the gap between the curtain wall and the slab. The fire rated bumper assembly includes a back plate configured for connection to either the curtain wall or the slab. A bumper is attached to the back plate and has an elongated body manufactured from a fire-retardant elastomer which encloses a high temperature insulation material.

Abstract: A sealing plug configured for sealing a passage of a curtain wall mullion. The passage has a maximum width and a length. The sealing plug includes a main body extending from a first surface to a second surface. The main body has a width at least as large as the passage maximum width and a length at least as large as the passage length. The main body is manufactured from a compressible foam. An intumescent layer is defined along at least one of the first and second surfaces.

Abstract: L-shaped bracket for securing insulation relative to a mullion or transom includes a side plate which defines a first major side of the L-shaped bracket and a flange which defines a second major side of the L-shaped bracket. The side plate defines at least one aperture configured to receive a fastener so as to facilitate attachment of the side plate to a side surface of the mullion or transom. A first receiving slot is disposed in the side plate and configured to receive a clip leg of a clip. The first receiving slot can be defined by a slot plate supported in spaced relation to a surface of the side plate. The clip is configured to engage the insulation.

Abstract: A bracket for securing insulation and/or a stiffener relative to a mullion or transom having a given width. The bracket includes a pair of legs extending from a bridge to define a receiving channel having a width equal to or smaller than the given width. The bracket can be attached to the mullion with friction. At least one of the legs defines a first receiving slot configured to receive a clip leg of a respective clip configured to engage the insulation, and an optional second receiving slot configured to receive a face of the stiffener. In an alternative configuration, the bracket can be attached to a side of the mullion via an existing anchor attachment near the floor line so that the anchor attachment does not interfere with the bracket.

Abstract: A firestop system for fire stopping a bus duct that passes through an opening in a marine deck or a marine bulkhead includes a boot seal wrapped around the bus duct housing. The boot seal has a top end attached to the bus duct, and a bottom end attached to the division. The boot seal is made of flexible material to allow for movement of the bus duct relative to the division due to vibration. The boot seal may be made of a thermal barrier wrap or other high-temperature insulating mat materials to allow heat generated under normal condition to escape while providing firestopping and temperature resistance under fire exposure conditions. The firestop system may also have a gasket positioned between the bus duct and the boot seal to accommodate irregularities in the outside surface of the bus duct housing.

Abstract: A firestopping apparatus including a housing defined by first and second housing members. Each housing member includes a width direction wall panel and a height direction wall panel. The width direction wall panel of the first housing member is configured to connect with the height direction wall panel of the second housing member and the width direction wall panel of the second housing member is configured to connect with the height direction wall panel of the first housing member to define an assembled housing with a through passage. Intumescent material is positioned along an inner surface of each wall panel. A compressible foam is positioned within the intumescent material and substantially closes off the through passage.

Abstract: Assembling a multi-story building using a prefabricating a curtain wall assembly (CWA) involves assembling a structural frame and preparing the frame to receive a thermal insulation panel in a spandrel area. A thermal insulation panel is then supported in the spandrel area using a flange plate of a plurality of brackets that are secured to the frame. The thermal insulation panel is engaged or secured using one or more clips which retain the panel to the frame. The process continues by attaching the CWA which has been prefabricated to a floor slab on the building to form a portion of the building curtain wall.
