Non-friable asbestos is a material containing asbestos locked into a hard matrix which prevents it from being crumbled, pulverized or reduced to powder by hand pressure. However, non-friable asbestos material can be made friable by grinding, sawing, abrading, cutting or crushing. The transite or cement asbestos shingles on your house are non ...

Asbestos cement Asbestos cement differs from AIB in that the material has a higher density and contains cement. This means that it is less likely to release asbestos fibres, and also has a greater capacity to repel water. As such, it is more suited to external applications but is not suitable as a fire-retardant board.

Asbestos is common in chimneys, furnaces, and wood stoves in homes and other buildings constructed before 1980 because of its abundant use in construction materials in past decades. Asbestos resists fire and heat, making it useful for insulation in stoves and furnaces. Originally used to make homes safer, these materials may release asbestos fibers and cause harmful exposure.
