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 sealing to seal a wall element with a fixed frame having mullions and transoms with perpendicular ends with which the transoms are attached between the mullions. The fixed frame is fitted with at least one compartment with a rebate for a frame part with an infill element to create a wing that opens, or to replace a damaged infill element, where the seal is intended to create a windproof and watertight connection between the mullions and transoms in the corners of an aforementioned compartment, where the seal is made as a corner piece that is formed and sized such that, on the level of the corners to be sealed, it fits in the form of the rebate in the mullion and transom in question and overlaps and covers the connection between this mullion and transom at the level of the rebate.

Embodiments described herein may be directed towards a male and female gasket coupling for securing adjacent window frames. In accordance with the present disclosure, the male gasket may comprise a head portion that creates a seal inside a cavity of the female gasket. The female gasket may further be enabled to collapse on itself as it engages a surface of the male gasket. The seal may be maintained when the male and female gaskets move toward each other or when the male and female gaskets move away from each other due to fluctuations in temperature.

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).

An expansion joint configured to connect first and second vertical mullions of a curtain wall is disclosed. The first and second vertical mullions may each include an elongated body having an inner contour defining a hollow slot, and an inner sleeve may extend through the hollow slot of both of the first and second vertical mullions. The expansion joint may comprise a body, and an inner contour defining a central inner slot configured to receive the inner sleeve therethrough. The expansion joint may further comprise a first raised lip projecting from a lower surface of the body and configured to be inserted inside of the inner contour of the first vertical mullion, and a second raised lip projecting from an upper surface of the body and configured to be inserted inside of the inner contour of the second vertical mullion. The expansion joint may be formed from a polymeric elastomer.

A mullion assembly is provided for forming a window assembly, the window assembly comprising a first window frame and a second window frame coupled to a monolithic mullion core such that a distal portion of the first window frame is in contact with a proximal surface of the mullion core and a proximal portion of the second window frame is in contact with a distal surface of the mullion core. The mullion assembly further comprises a first and second female connector on a respective first and second side of the mullion core. A plurality of separate compartments is defined along a length of the mullion core vertically between the proximal and distal surfaces and laterally between the first and second female connectors. The mullion assembly further comprises first and second male connectors configured to engage the female connectors and seal the first and second sides of the mullion core.

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.

A building facade system which comprises an anchor. The anchor having a flange extending in a first horizontal direction and serrations along a portion thereof. A vertical mullion being held in shear and secured by shear connection to the anchor to support horizontal members forming a frame for supporting a building facade panel. The shear connection formed by a fastener coupling the anchor to an outside lateral surface of the vertical mullion. The fastener extending in the second horizontal direction through the anchor and the vertical mullion. The angle member having first and second flanges having proximal ends joined together and opposing terminal ends. The second flange being engageable with the flange of the anchor by way of a vertically-oriented coupling securing the flange of the anchor and the angle member. The angle member being securable to a building floor slab and supporting the anchor thereon.

A glazing shield system for retrofitting glazing systems of buildings is disclosed. The glazing shield system includes a support frame and a unitized panel. In certain embodiments, the glazing shield system may be mounted on an existing glazing system in a non-intrusive and non-destructive method. In one embodiment, the support frame may be attached to an infill panel of an existing glazing system using structural adhesives, and the unitized panel may be mounted on the support frame, creating an insulating glazing shield.
