    What is Marmox Multiboard Ultra made of?

    MARMOX Board Ultra is an extruded polystyrene board, covered on both sides with an ultra thin polymeric cement mortar, reinforced with alkali resistance glass fiber mesh,providing a very special surface texture which ensures excellent adhesion to renders and adhesives.

    This de-coupling layer gives the Multiboard Ultra the same property as a crack isolation mat. Lateral movement in the floor and wall will not be transmitted to the rendered, finished or tiled surface.
