Overview
Flat Cement-Bonded Board is a functional cement-bonded particle board with identical flat faces in the natural grey of its cement and wood. It has many uses from floor to roof and is an ideal building board for prefabricated and steel-framed buildings.
It works as subfloor, raised-floor and mezzanine panels, as partition and lift-shaft walls, as roof sheathing and as a backer board for interior and exterior cladding or tiles in wet spaces. It is compatible with underfloor heating and resists the biological waste of animals.
On exteriors, facades, outdoor ceilings and soffits are recommended only for prefabricated and light steel buildings. Tile backing in wet spaces applies only to boards fixed mechanically to a metal frame.
Performance
- 01
Floor to roof
One board for subfloors, walls, ceilings and roof sheathing.
