A first embodiment of an aluminium extrusion framing system (10) comprises a first wedge member (12) and a second wedge member (14) made of resilient material for securing and sealing a panel (16) in the framing system. The framing system (10) also comprises an aluminium extrusion (20) having a channel (22) adapted to receive an edge of the panel (16) therein. A first side wall (24b) is formed with a first elongate retention means (28) extending the full length of the extrusion (20) for receiving the first wedge member (12) in connection therewith. A removable cover plate (30) is adapted to be secured to the extrusion (20) and received in close proximity to a top edge of the first side wall (24b) of the channel (22) whereby, in use, when the panel 16 is installed in the channel 22 with the first wedge member (12) received in connection with the first retention means (28), the first wedge member (12) is substantially concealed when the removable cover plate (30) is secured to the extrusion (20).

A window system for a building includes a panel and a first element assembly that supports the panel and includes a cross member and a pressure plate laterally offset from the cross member. A glazing pocket is defined between the cross member and the pressure plate, and a thermal separator is positioned within the glazing pocket and extends between the pressure plate and the cross member. The thermal separator includes a tongue extension and a rod gasket seals an interface between the tongue extension and the cross member.

An exterior wall system includes a pair of split vertical members. A front-load bay is defined between the pair of split vertical members. The front-load bay includes a horizontal member disposed along a bottom edge of the front-load bay. Each split vertical member includes a removable portion coupled to a vertical edge of the front-load bay and a fixed portion coupled to an adjacent section of the exterior wall system. The removable portion may be selectively coupled to the fixed portion to facilitate assembly of the front-load bay to the adjacent section of the exterior wall system. A sill starter is disposed horizontally between the pair of split vertical members below the front-load bay. The horizontal member engages with the sill starter to facilitate support of the front-load bay.

Methods, structures and systems for environmental isolation of metal window, transom and mullion surfaces, including in one aspect a metal frame structure configured to receive an operable window, the frame structure having a first thermally insulated polymer component connected to a side of the frame structure at a side wall and spanning a total width of the side wall, and an operable window having a second thermally insulated polymer component connected to a sash assembly, the window configured to close to a position defining a first gap between the second thermally insulated polymer component and the first thermally insulated polymer component and a second gap between the sash assembly and the frame structure. In one aspect at least one seal is positioned in the first gap and abutting both the second component and the first component and at least one seal positioned in the second gap and abutting both the sash assembly and the frame structure to provide improved insulation effectiveness.

A façade system includes a mullion having exterior and interior portions and defining a glazing pocket between the exterior and interior portions, a thermal break arranged within the glazing pocket and extending between the exterior and interior portions, the thermal break dividing the glazing pocket into a shallow pocket and a deep pocket larger than the shallow pocket, and a collapsible element arranged within the deep pocket and extending between the thermal break and a lateral side of a panel introduced into the deep pocket. The collapsible element is movable between a collapsed state and an expanded state. The collapsible element divides the deep pocket into two or more thermal chambers when in the expanded state to reduce heat transfer by convection through the glazing pocket.

A pultrusion fiber reinforced polymer (PFRP) floor assembly comprises a plurality of PFRP trusses or joists connected to at least one horizontal PFRP I-beam, horizontal PFRP wide flange beam, or horizontal PFRP “C” channel. At least one PFRP clip angle bracket connects the plurality of PFRP trusses or joists to support PFRP floor sheathing. A flexible epoxy bonds the PFRP floor sheathing to the plurality of PFRP trusses or joists, horizontal PFRP I-beams, horizontal PFRP wide flange beams, or horizontal PFRP “C” channels. The flexible epoxy is configured to provide a uniform coefficient of thermal expansion throughout the PFRP floor assembly.

An approved dynamic construction is used for effectively thermally insulating and sealing of a safing slot between a floor of a building and an exterior wall construction. The exterior wall construction includes a curtain wall configuration defined by an interior wall glass surface including one or more aluminum framing members, where the vision glass extends to the finished floor level below. The dynamic, thermally insulating and sealing system includes a first element for receiving the insulating elements, and is positioned in the zero spandrel area of a glass curtain wall construction including only vision glass, to maintain thermally insulating and sealing of the safing slot during exposure to fire and heat as well as movement in order to maintain a complete seal extending across the safing slot.

A glass fastening system includes a glass portion, a support structure defining a recess, a first adhesive layer disposed on an exterior surface of the glass portion facing the recess in the support structure, a second adhesive layer disposed within the recess of the support structure, and a fastener having a first portion secured to the first adhesive layer and a second portion extending away from the first portion and into the second adhesive layer to secure the glass portion to the support structure.

A toggle insert for receiving a toggle assembly in a steel curtain wall structure is disclosed. The toggle insert is a self-leveling profile requiring no welding for fastening to steel curtain wall structure and further provides a screw tolerance of up to 1 inch for locating and fastening toggle screws during installation of glazing elements to the steel curtain wail structure. The toggle insert includes a horizontal section having a front portion, an intermediate portion and a bottom portion, wherein the front portion includes a central elongated opening measuring between 21 mm and 25 mm sandwiched on either sides by slotted screw race and a pair of threaded set screws for leveling into the slotted screw race that fixes the toggle insert by way of wedging into the steel curtain wall structure.
