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.

A curtain wall constructed from prefabricated connecting wall elements mounted in rows next to and above each other with the wall elements including a frame of assembled profiles on the inside of the curtain wall and of one or more infill elements on the outside of the curtain wall. The frame contains mullions and transoms in the form of profiles which along the perimeter of the frame have female coupling parts and male coupling parts which allow the adjacent mullions and adjacent transoms in an assembled condition in the curtain wall to engage with their coupling parts to form composite basic profiles, where between two rows of connecting wall elements a horizontal seal has been applied which extends continuously in a horizontal direction over the width of the underlying row.

A curtain wall includes one or more mullions and one or more transoms and panels that are fitted with their edges at least in the mullions and optionally in the transoms. The mullion is assembled from at least an inner profile and an outer profile joined together by means of one or more plastic profiles, wherein at least the inner profile consists substantially of steel.

A wall system for a building (such as an exterior façade for a building) may include a frame structure configured for attachment to the building. The frame structure may include a plurality of horizontal frame elements, a plurality of vertical frame elements, and an energy distribution system including an elongated conductive bar at least partially positionable within at least one of the horizontal frame elements or at least one of the vertical frame elements. The system may include one or more access elements positionable to engage the elongated conductive bar to receive electricity or a data signal from the elongated conductive bar. The frame structure may support infills that connect to the elongated conductive bar and use or produce electricity.

A curtain wall construction system comprises a plurality of interconnected curtain wall supporting beams; one or more elongated and compressible sealing elements attached to at least one of the curtain wall supporting beams, wherein the curtain wall construction system is configured with a dedicated interspace within which a corresponding set of one or more rigid and impermeable panels is introducible. The curtain wall construction system further comprising a linearly displaceable clamping element that is clampable against the introduced set of panels to form a clamping arrangement which provides sealing protection in conjunction with the one or more sealing elements.

A building facade system which comprises a frame to support a building facade panel, a unified vertical shear blade anchor, a vertical mullion and an angled anchor member. The unified vertical shear blade anchor has a body portion and a flange extending horizontally therefrom. The flange has top and bottom surfaces with the bottom surface having serrations. The vertical mullion is secured by a shear connection to the vertical shear blade anchor. The shear connection between the vertical mullion and the vertical shear blade anchor is formed by a fastener which extends through side portions of the body portion and vertical mullion. The angle member has first and second flanges each having proximal ends joined together and opposing terminal ends. The second flange has a top surface with upwardly projecting serrations. The upwardly projecting serrations are configured for engagement with the downwardly projecting serrations of the vertical shear blade anchor.

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.
