Asbestos cement is a fragile material and is not weightbearing. Never go onto it without crawling boards. This should not be necessary when removing sheets. If you are working from a ladder, ensure it is in good condition. Ensure that you have someone to help by steadying the foot of the ladder. If the location is very high, awkward, or the job is likely to take a long time, it may be safer ...

Asbestos insulating board, also known as "AIB" or by the trade name "Asbestolux", was an asbestos containing board used in the building trade because of its excellent fire resistance and heat insulating properties. These boards were commonly used in the UK from the 1930s up until production was terminated in 1980.

In cement sheeting the asbestos fibres are bound in a cement matrix, while in fibre boards the asbestos fibres are bound in calcium silicate plaster. This makes the board quite soft and if a fingernail is pressed into the surface it can leave an indentation. It is usually painted white.

n A dense, rigid, board containing a high proportion of asbestos fibers bonded with Portland cement; resistant to fire, flame, and weathering; has low resistance to heat flow. Used as a building material in sheet form and corrugated sheeting (Harris CM (2005) Dictionary of architecture and construction. McGrawHill, New York).

· Asbestos cement is usually manufactured using chrysotile (white asbestos), although crocidolite (blue asbestos) and amosite (brown asbestos) are used for some products. The asbestos fibres and fibre bundles usually exhibit a preferred orientation subparallel to the length of the sheet, tile, or pipe that they are incorporated within. Traces of the asbestos host rock such as serpentinite ...

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. The 1990''s saw the introduction of ...

Asbestos cement is primarily a cementbased product where about 1015% w/w of asbestos fibres are added to reinforce the cement. As well as an insulation and fireproofing aid, asbestos cement was used due to the fact that it is weatherproof in that, although it will absorb moisture, the water does not pass through the product.

· Various products for use in buildings are made with a mixture of 8 to 20 per cent of asbestos with Portland cement. These products are called asbestos cement products. Asbestos cement products are light in weight, strong, durable, water proof and resist corrosion. These can be sawn, drilled and drilled, nailed and screwed.
