Cembrit’s versatile building board, Cembrit PB, which is ideally suited as a stable base for a range of internal and external applications is now available in flex formulation. Cembrit PB Flex has been specifically developed for use on curved walls, arches, vaulted ceilings and around beams and columns.

Cement-based Cembrit PB delivers impressive dimensional stability and water resistance, to minimise expansion and contraction as a result of heat, cold and moisture. Its 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. With the newly-launched Cembrit PB Flex, it is now possible to render onto curved surfaces, including columns, spiral staircases and archways.

“We are confident that Cembrit PB Flex will help to make the life of the installer easier,” comments Cembrit Marketing Manager, Ged Ferris. “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.”

Compared to standard Cembrit PB, Flex 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. The 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. Cembrit PB Flex can be curved to 90° with a minimum radius of 150mm.

Cembrit’s 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. Highly resistant, Cembrit PB impedes both fungus and mould to sustain a healthy, durable environment.

Using skills built up over 80 years, Cembrit offers a wide range of fibre cement and natural slates, as well as corrugated sheets, cladding and building board panels. Our factories operate Environmental Management Systems (EMS) to EN14001. Environmental Product Declarations (EPD) are available on all Cembrit manufactured ranges and Cembrit fibre cement slates are listed on the Greenbooklive.com register of environmental products. Quality levels at group factories are rigorously maintained to high standards, with many products manufactured under the control of ISO 9001 and British Board of Agrément. Cembrit UK is a member of Cembrit Holding A/S of Denmark.
