Is it Asbestos?
Not sure if the item contains asbestos? There are two classes of asbestos types.
Friable (Class A) Asbestos is classified as any material found under ground level, as well as a few older forms of insulation used in domestic heaters and stoves and in ceiling insulations products. Ceiling insulation containing asbestos was generally used in commercial buildings. In most cases, glass fibres have replaced asbestos in today's insulations products.
Bonded (Class B) Asbestos is a fibre-cement product. The asbestos in firmly embedded in a hardened matrix. The bonded sheets are flat, corrugated or circular tubes.
