The calcium silicate boards can also be stacked on the wall, but we recommend that you use a thicker board thickness directly. On the one hand, the amount of work involved is almost twice as high, as you have to glue 2 (or more) panels on top of each other, and on the other hand you need more adhesive, which results in unnecessary costs. If it is only a small area - e.g. a radiator recess or similar - you can of course glue one panel on top of the other.
For larger quantities, however, we recommend going straight for the thicker sheets. In addition to our standard thicknesses, we can also offer you all other thicknesses - please do not hesitate to contact us.
