The penetrating transom have a transom body portion and a transom nose portion. The transom nose portion has extensions extending beyond opposed ends of the transom body portion received in the notches of the mullion body portions 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 mullions and transoms 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.
