Example of highly damaged asbestos insulating board (AIB) panels to the underside of pitched roof sections in an old industrial building. The panels had been smashed through in order to fix the gutter above, leaving asbestos debris to all lower level surfaces.
AIB is commonly used for fire protection, thermal and acoustic insulation & as general building board. It can be also be found in service ducts, firebreaks, infill panels, partitions and ceilings (including ceiling tiles), roof underlay, wall linings, soffits, external canopies and porch linings.
AIB usually contains a mixture of amosite (brown) and chrysotile (white) asbestos fibres in a calcium silicate.
Almost all work with AIB will require a licensed contractor.
