JOINT SIZES

When constructing glass block walls using 190x190x80 or larger dimension glass blocks, Glass Block Technology recommend the use of 10mm horizontal and vertical joints.

SPACER PEGS

10mm spacer pegs are available to assist with accuracy of construction and prevent mortar squeeze.

Glass Block Technology also has a 6mm horizontal and vertical spacer peg in the product range, this can be used only in conjunction with 80mm thick glass blocks. It is primarily used in conjunction with smaller glass blocks for example - 115x115x80, 190x90x80 or for curved glass block screens where it is subject to a tighter than recommended radius.

When the spacer peg is fitted and the wall is finished, the tabs at the end twist off and this is then grouted over.
