Cembrit PB Flex enables curves to be created
Cembrit PB Flex for curved walls, beams, columns, arches and vaulted ceilings
Cembrit PB is a versatile building board providing a stable base for a range of internal and external applications. Low water absorbency makes Cembrit PB ideal for use as a tile backer board for any internal wet area application where ceramic tiles will be used as the decorative finish, as well as externally for applications such as rendering, brick slips or stone cladding.
- delivers dimensional stability and water resistance, to minimise expansion and contraction as a result of heat, cold and moisture
- supported by both British Standard and North American performance tests
- highly resistant, impedes both fungus and mould
Rendering onto curved surfaces with new Cembrit PB Flex
Now available in flex formulation, cement-based Cembrit PB Flex has been developed for use on
- curved walls, arches, vaulted ceilings and around beams and columns.
- render onto curved surfaces, including columns, spiral staircases and archways
Ged Ferris, Cembrit Marketing Manager: Cembrit PB Flex will help to make the life of the installer easier. For contractors working on rendering projects with curved surfaces, Flex is the ideal solution. Rather than requiring mechanical cutting, Cembrit PB Flex can be scored and snapped, making it incredibly user-friendly. We have a network of nationwide stockists ready to supply the product, which will ensure impressive and convenient lead times.
Advantages of Flex compared to standard Cembrit PB
- offers reduced dimensions of width and weight per panel
All Cembrit PB boards contain polystyrene beading, which makes them remarkably lightweight in comparison with stone, block and concrete.
Strengthened with nylon mesh, the boards also boast an especially reinforced, tapered edge to allow an invisible fixing within 10mm of the board’s edge.
- configuration of PB Flex maximizes stability at the butt joints and forms a tough structure to ensure a long-lasting result over the lifetime of the installation
- can be curved to 90° with a minimum radius of 150mm
