Disclosed is a wall framing system having vertical and horizontal mullions each formed of an interior piece and an exterior piece connected together by internal plastic clips. Water diverters are mounted internally of the horizontal mullions for diverting intruded water to exit points on the exterior sides of the mullions. At the crossings of vertical and horizontal mullions, internal water diverter bridge pieces connect through the vertical mullions from the water diverter in one horizontal mullion to the water diverter in the other. The vertical mullion faces each have a height substantially equal to a coextensive with the panels they grip to facilitate glazing and reglazing. A special open channel horizontal mullion with joint forming flanges therein is disclosed, together with a novel snap lock cover system therefor. Installation of the wall system is facilitated by deep glazing pocket vertical jambs, the two piece vertical mullions, and assymetrical glazing gaskets.
