Abstract: An assembly of glass blocks held in a structural frame comprises a plurality of glass blocks, a rectangular structural perimeter frame, a plurality of primary muntins, each said primary muntin comprising an elongate web, the primary muntins extending entirely across the structural perimeter frame, a plurality of extruded secondary muntins, and a plurality of structural rods inserted through the secondary muntins and extending entirely across the structural perimeter frame, such that the primary and secondary muntins form a matrix within the structural perimeter frame with openings for receiving the plurality of glass blocks.

Abstract: An assembly of glass blocks is held in a structural frame and comprises a plurality of glass blocks each having two rectangular display faces and four edge faces; a rectangular structural perimeter frame having four sides; and a plurality of primary muntins, each primary muntin connected to the rectangular structural perimeter frame and comprising an elongate web with stand-offs lying within parallel planes and extending outward from the web and at least one elongate hollow boss integral with the web positioned within the planes, the primary muntins extending entirely across the structural perimeter frame, wherein the primary muntins define an array within the structural perimeter frame with openings for receiving the plurality of glass blocks.

Abstract: A framing system is provided for supporting glazing elements on a substrate, such as a building framework or an existing glazing system. The framing system includes a plurality of frames surrounding and supporting respective glazing elements. A plurality of frame members are joined to form sides of each frame. Each frame member includes a rabbet for receiving the glazing element having a pair of spaced sides and a base connecting said spaced sides, and a flange extending outwardly from the rabbet base. Flanges of frame members overlap with flanges of adjacent frame members of adjacent frames. Fasteners extend through the flanges for attaching the framing system to the substrate.
