How this node works
The north glazing is clamped to the steel mullion by a pressure plate over gaskets, inner and outer. A small channel inside collects the condensation that forms on the cold glass and drains it out by a weep, while the inner gasket makes the air seal. A drip throws the water clear of the frame.
