Builders used asbestos cement soffit boards, called Asbestolux, Asbestos Cement Mix (ACM) or Asbestos Insulating Boards (AIB) from the late 1940’s up to the early 1980’s. From the early 1980’s, thin ply board gradually replaced asbestos as the preferred choice for soffits, this was, in part, due to the introduction of asbestos control regulations. Asbestos was used in a number of different materials that were used to create walls, which makes visual identification difficult. Some of the most common types of ACM that were used to create walls include asbestos insulation board (AIB) and cement sheets. AIB’s were used in both commercial and domestic properties to create walls. Over time asbestos sheets may have been replaced with asbestos-free alternatives, but if they are particularly old and look weathered, they are likely to contain asbestos cement. Asbestos sheeting identification can be presumed by getting an idea of how long ago the sheeting was installed (before or after the 1990s) and whether it was ever replaced.

Asbestos cement is primarily a cement-based product where about 10-15% w/w of asbestos fibres are added to reinforce the cement.

Asbestos cement, genericized as fibro or fibrolite - short for "fibrous cement sheet" - and AC sheet, is a building material in which asbestos fibres are used to reinforce thin rigid cement sheets. Although invented at the end of the 19th century, the material rose to necessity during World War II to make sturdy, inexpensive military housing, and continued to be used widely following the war as an affordable external cladding for buildings. Advertised as a fireproof alternative to Asbestos-Cement Siding Basics. Homes built between 1920 and the 1960s are likely to contain asbestos in any cementitious siding tiles. Cementitious siding installed after 1973 is very unlikely to contain asbestos. These materials are known as fiber-cement siding and they contain no asbestos.

Cement sheeting was made of asbestos fibres and cement mix. The cement mix locked in the asbestos fibres. Flat sheet fibro was the most common asbestos cement sheeting. It was nailed to a wooden frame for quick and cheap construction and may have been painted over. You should know that asbestos is a mineral and cement sheets, or fibro. These are those materials which are beneficial because the building materials are developed by using asbestos and cement blend. The natural developing asbestos arises as an extensive and fine form of fibrous crystals.
