Abstract: A glass construction block comprising a plurality of glass members, each of which has a front wall, a rear wall and a plurality of side walls. A frame surrounds the glass members and is secured to the glass members spacing the glass members apart from each other while holding the glass members in a static position. The frame defines a channel member with side walls which extend inward from the outer side edge of the glass members terminating in a bottom wall and has flange portions which extend outward and are secured to the side walls. The blocks are assembled as a wall system by fitting a positive rib placed into the channel member into the channel member of an adjacent block. The two are adjoined with a void between the edges of the blocks which is then filled with a sealant.
