MARMOX Rock Board PRO –
non combustable
MARMOX Rock Board PRO – non combustable is a lightweight construction board with the non-combustablöe core made of mineral wool. The surfaces are coated with a cement based special mortar, reinforced with glass fibre mesh. The coating is water proof against zero water pressure. The outstanding feature of MARMOX Rock Board PRO – non combustable is the direction of the mineral fibres which are vertical to the cement coated surface. That improves the stability of the board and reduce the risk of delamination considerable.

MARMOX Rock Board PRO – non combustable are easy to cut on size by cutter or saw. The fastening can be done with glue, either applied on the full surface or alternative with dabs of glue. The boards have to be laid in a staggered pattern, aligned vertically and horizontally. Once the tile adhesive cured, drill the holes into the wall at the dabs position, insert dowels, washers and stainless steel screws/nails. Cover all joints and washers with glass fiber mesh or sealing tape, embedded in a layer of flexible glue.
