Doors and windows

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. 

Standard surface compressed asbestos cement (AC) sheets are smooth on both sides, or smooth on one side with a patterned surface on the other side. They may be painted. Their main use was balustrades and windowsills.
