Fireplaces

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. They were often painted white. The fibre boards are quite soft – you can leave a mark with your fingernail.  

Asbestos millboard was mostly used for insulation and fire protection, and around heating elements in air conditioning ducts. 

Movement joints of 30.5 centimetres (1 foot) lengths were made with soft, non-hardening caulking material. The caulking forms a flexible seal used in seams, joints and openings between pipes, planks and wall sections. 

Sealants used like caulking – to prevent the transmission of dust, sound and heat – may contain asbestos.
