Cembrit is pleased to announce their versatile new base board specially designed for insulated render systems. With the application of liquid renders, specifiers can create facades combining a monolithic appearance with all the advantages of rainscreen claddings.
Cement based Cembrit PB, has low water absorbency and is dimensionally stable. It wont expand and contract with heat and cold nor will it swell and shrink due to changes in moisture, crucial characteristics inhibiting surface cracking in the render finish. Cembrit PBs specially developed reinforced, chamfered edges mean the board can be fixed close to their edges. This maximizes stability at the butt joints, further reducing the risk of the render cracking along the joints, which can be a vulnerable area of the facade.
Cembrit PB has an innovative composition which should please the installer. The boards contain polystyrene beading reducing the weight of the board in comparison with stone, block and concrete. Cembrit PB can be scored and snapped rather than requiring mechanical cutting. Cembrit PB could well be the most user friendly renderbacker available in the UK; it is certainly one of the lightest!
The features which make Cembrit PB an ideal renderbacker also make it an excellent tile backer board for any internal wet area application where the finish will be ceramic tiles.
Cembrits PB boards are tried and tested in all climates across North America and Europe and are supported by both British Standard and North American performance tests.
