When applied in layers, e.g. with flexible mineral wool or ceramic mat core, it combines the positive properties of mineral wool
(it is lightweight, provides fire protection, thermal and acoustic insulation) with the very good composite characteristics (high fire
resistance, resistance to moisture and swelling in water). The composite, as a rigid board, is easy in erection with typical carpentry
tools. The wide range of board thicknesses enables the selection of the most economical composite for the prescribed fire
protection class. The composite board edges are bevelled along the long sides, enabling their exact assembly.
