Cembrit, the roofing slate and cladding specialist, will be demonstrating its new versatile building board, Cembrit PB Flex at this year’s National Homebuilding & Renovating show (26th – 29th March 2015, NEC Birmingham) on stand F125.

Specially designed for use on curved walls, arches, vaulted ceilings and around beams and columns, Cembrit PB Flex makes it possible to render onto curved surfaces, including columns, spiral staircases and archways.

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

Cembrit PB is a versatile base board specially designed for insulated render systems. 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.
