The roof is sheeted with corrugated fibro sheets and the walls with flat fibro sheeting, with fibro battens covering the joints.

[1] Asbestos abatement is utilized during general construction in areas containing asbestos materials, particularly when those materials are being removed, encapsulated, or repaired.
AIB is 16-35% asbestos, typically a blend of amosite and chrysotile, though crocidolite was also used in early boards. AIB is softer, more porous and less dense than asbestos cement . This, and the fact it typically contains a greater proportion of asbestos than the 10-15% of asbestos cement, [ 2 ] makes AIB far more friable and thus at greater ...
Principally he mixed 90% Portland cement and 10% asbestos fibres with water and ran it through a cardboard machine. Originally, the fibres were of asbestos and the material was commonly used as siding in house buildings due to its low cost, fire-resistance, water tightness, lightweight, and other
The regulations did not prohibit the continued use of asbestos-containing materials that were already in place such as asbestos-cement roof sheets or ceilings, the department was satisfied that there was "no undue risk" and they would be replaced in due time.
