2.1 BRICKS & BRICK OUT DETAIL
Brick size and refractory:
The standard brick out is the stretcher bond style. However, other styles can be bricked
according to your liking. Some bricklayers prefer to us their own refractory. Please check with
the bricklayer.
Bricks come in a standard size of 230 x 115 x 75mm. 25 mm and 40 mm thick bricks are
available, at a higher cost however due to more bricks being necessary for the brick out.
The figures below show different pattern styles that are bricked with the standard brick size of
230 x 115 x 75mm.
