The suitable glass thickness depends on the panel size, balustrade system, fixings and loads. Common laminated glass thicknesses used in balustrades include 8.76 mm (two 4 mm panes) and 12.76 mm (two 6 mm panes). Thicker glass is not automatically better or safer.
The glass and fixings must be specified to work together. Consider the post spacing, glass height, type of clamps or profiles and whether the glass is laminated or toughened laminated. The finished glass panel must be slightly smaller than the opening between posts to allow for fittings and installation tolerances.
