In the construction of glass flooring, the structural glass in the form of tiles, blocks, etc., is fitted within frames of various types. The structural glass is available in different forms of varying thicknesses, usually from 10 to 30 mm. The frame-work containing structural glass blocks should be closely spaced that the glass flooring can safely sustain the anticipated loads.
