Walls

Fire dampers used to prevent fire in heating, ventilation, and air conditioning (HVAC) ducts may contain asbestos. Fire dampers are used in walls and ceilings, often in the duct system, to create sections that stop fire spreading.

Sheets that contain asbestos are found as the base and around fireplaces. They are also found around wood fire heaters, around gas heaters and also as the wick in kerosene heaters.

Imitation brick cladding was usually nailed onto asbestos cement sheeting. The cladding itself may or may not contain asbestos. 

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.
