High-performance cement bonded particle building board
RCM Cemboard is a rigid, medium density, high-performance cement bonded particle building board which offers great strength and stability with the workability of wood.
Cemboard is used primarily as an external sheathing board. It provides excellent acoustic properties making it an excellent acoustic building board. Used extensively on both metal and timber frame structures, it is also a great choice for modular and offsite builds.
Cemboard can be used behind all types of façade solutions, as well as in many acoustic floor and roof constructions.
