• the composite stone can be bricked like a normal brick and / or glued with thin bed mortar or the like, and the integrated insulation layer can be provided with a plaster layer or with a facing brick.
• the tongue and groove connection creates a permanent connection between the clay brick and the foam clay insulation layer.
• foam clay as an insulating layer in a masonry clay brick for the composite stone has the advantage that the composite stone can be manufactured in one operation.
• perforated bricks is of particular advantage, since their surface-side channels only have one along running recess, for example for the T-web to form a T-groove, need to be provided. This is expediently already done during the production of the blank.
• the production of the composite stone according to the invention is simplified and inexpensive, because foam clay raw material with or without shape in the desired thickness simply needs to be applied to the grooved brick blanks.
• the foam clay flows into the grooves and also connects superficially to the brick blank.
• the brick blank and the foam clay applied can then be dried and fired together in the composite.
• the insulation layer can then be ground flat and calibrated if necessary.
