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

A window assembly may include a vacuum insulated glass unit and a frame assembly. The vacuum insulated glass unit may include first and second glass substrates defining a space therebetween that is at a pressure lower than atmospheric pressure. One of the first and second glass substrates may include a vacuum port extending outward therefrom. The vacuum port may define a passage in communication with the space. The frame assembly supports the glass unit and may include a base member and a glazing member. The base member and the glazing member cooperate to define a slot in which an edge portion of the glass unit is received. The glazing member may include a cavity receiving the vacuum port.
