Knauf’s PERMAROCK® Cement Board (Outdoor) is made of Portland cement and aggregate core, with coated glass fibre mesh embedded in back and front surfaces. It is a solid, engineered, inorganic wall lining that is 100% water and mould resistant.
The ends of the boards are square cut and both edges are reinforced and finished smoothly. PERMAROCK® Cement Board Outdoor is an extremely durable building material, providing a solid and dry foundation that can withstand harsh climates including high winds, rain and snow.
It can be used as a substrate for ventilated exterior walls and also for directly applied systems using water-managed design principles.
PERMAROCK® Cement Board Outdoor is the ideal render or tile substrate for external walls and ceilings in commercial, residential and industrial applications. It is also perfect when finished with decorative coverings or paint.
PERMAROCK® is suitable for replacing facades or renovating existing buildings as the lightweight nature of the system means that additional reinforcement of the primary structure is not required.
