Low-density asbestos fibre boards look similar to asbestos-containing cement sheeting or plaster board. They were used as wall and ceiling panels, particularly in areas of high humidity. Also used as sound insulation boards in plant rooms. They were often painted white. The fibre boards are quite soft – you can leave a mark with your fingernail.
Fibre boards contain up to 70% asbestos fibres, bound in calcium silicate plaster. It can be hard to tell the difference between these boards and other construction sheeting. They can be can be perforated sheeting.
These boards are unlikely to be found in properties built after 1983.

Edges of a board may be roughly bevelled.
Heads of fasteners (clout nails) are often pushed into the surface – they stick out on asbestos cement sheeting.
