Also known as an acoustic ceiling great for reducing noise & for its fire resistance capabilities, it is a spray-on textured finish. This style of ceiling coating was popular within the building & construction industry & widely used in multilevel unit & apartment buildings, but fell out of favour in the 1980’s when the harmful effects of asbestos were discovered.
Although not all vermiculite contains asbestos, some products were made with vermiculite that contained asbestos until the early 1990s.Vermiculite mines throughout the world are now regularly tested for it and are supposed to sell products that contain no asbestos.
Pure vermiculite does not contain asbestos and is non-toxic. Impure vermiculite may contain, apart from asbestos, also minordiopside or remnants of the precursor minerals biotite or phlogopite.
Laboratory testing is the only way to tell whether a vermiculite ceiling contains asbestos.
Precautions should be taken before you take samples of any suspected asbestos containing materials. Please refer to the Queensland Governments web site www.deir.qld.gov.au/asbestos for more information.
