Cemboard is a rigid, medium density, high performance cement building board which combines the strength and durability of a concrete product with the workability of timber. This board retains its integrity and properties after being subjected to many cycles of soaking, freezing and heating.
Cemboard is classified as a Class’O’ building material and it can be used in the construction of fire resistant building elements. Cemboard fire rated partition systems have been tested in accordance with BS 476: Part 22:1987 (Methods for determination of fire resistance of non-load bearing elements of construction). 1 and 2-hour fire rating systems are available to cater for most local building regulation requirements.
This board is also classified as a sheathing and acoustic building board. The product is used extensively as an outer sheathing board onto metal and timber frame structures, behind the outer cladding finish.
Cemboard can be used for a variety of general purpose applications: behind external cladding systems as a sheathing board, or in acoustic applications in walls, floor and roof structures.

Cutting Drilling and Nailing
Cemboard can be cut, drilled, nailed and worked in a similar fashion to timber and chipboard with standard wood working tools, but offers a much longer performance life. It can be cut easily on site with tungsten carbide tipped saws.
Cemboard has a smooth surface which can be coated with minimum preparation. Alkali resisting paints can be applied directly on to the board. For other types of paint, an alkali resisting primer should be applied first.

Cemboard can be virtually maintained for free and so this board provide a real cost effective choice.
