  • Curtain wall assembly of interfitting glass blocks
    Patent number: 4023319
    Abstract: A decorative partition or like curtain wall structure is disclosed which can be formed by stacking a number of elementary glass blocks within a generally rectangular supporting frame. Each glass block has at least top and bottom faces contoured correspondingly for interfitting engagement with similar faces of the upper and lower blocks. The opposite lateral faces of each block may also be contoured correspondingly for interengagement with similar lateral faces of the blocks on both sides. Vertical bracing rods can be used to increase the stability of the glass blocks.
