Wood-cement composites

Product description

Wood-cement composites (also known as fibre-cement) are produced by mixing small pieces of wood with cement under pressure. They are produced in a range of shapes and sizes. Non-structural applications include acoustic ceiling tiles, siding and roadside noise barriers. Structural uses include concrete-filled insulating forms.

Technical information

Wood-cement composites can be made from a variety of different-sized and -shaped wood elements. A porous, low-density panel is made from wood wool (long thin slivers of wood), while a product more similar to conventional particleboard is made from wood particles and shavings. Sawdust and fibres can be used to make moulded products.

Wood-cement composites use much less wood than other wood panels, and in some instances the wood component of the product can be considered as filler to decrease the amount of cement used. Some wood species are not suitable because sugars and other chemicals contained in the wood inhibit the curing of the cement.

Wood-cement composites have good moisture resistance and dimensional stability as long as the edges are sealed, but are more difficult to cut and fasten than traditional wood-based composites. They have very good acoustic and insulating properties.
