A curtain wall system of the type having a framing of mullions and transoms adapted to support panels. The mullions have a mullion body portion and a mullion nose portion projecting from the mullion body portion and spaced notches in the mullion body portion. The penetrating transom each have a transom body portion and a transom nose portion projecting from the transom body portion. The transom nose portion has extensions extending beyond opposed ends of the transom body portion, the extensions being received in the notches of the mullion body portions such that the penetrating transoms are supported by the mullions. whereby the framing portion is formed for sealing receiving a panel to form an air barrier, with a gap being defined between the extensions of the transoms and the mullion nose portions. Pressure plates are connected to the mullion nose portions and to the transom nose portions to form a sash with the framing portion so as to secure the panels within the sash. A seal member blocks each gap to form a pressurized cavity with the sash about the glass panel.
