Low Density Board (LDB) is a lightly compressed asbestos sheeting which looks similar to asbestos cement (AC) sheeting. It is different because it can be easily bent by hand or dented by soft pressure. It is also sometimes referred to as asbestos insulating board.
LDB was manufactured from the 1950s to the 1970s as flat and perforated sheet products and was used for wall and ceiling panels, thermal and acoustic insulation, fire protection and for general building work in industrial and commercial buildings, education facilities and domestic premises. It was sold under product names such as ‘Asbestolux’ (the James Hardie product) and ‘Duralux’ (the Wunderlich product).
LDB contains up to 70 per cent by volume of asbestos fibres and is generally composed of amosite (brown asbestos) and chrysotile (white asbestos) in a calcium silicate plaster. If in good condition and left undisturbed, LDB presents a relatively low risk of releasing asbestos fibres and causing harm.
However, because it is softer than AC sheeting, LDB can break up more easily when disturbed, which increases the likelihood of exposure to airborne respirable asbestos fibres.
Irwin Services specialises in the removal of LDB with over 15 years experience with friable asbestos removal.
