Asbestos awareness is key to ensuring the health and safety of everyone, we hope you find the general information being provided about the more common asbestos containing materials (ACMs) found in our community helpful.
Below is some information on loose fill asbestos insulation. Our previous newsletters have covered asbestos cement
and asbestos insulation boards
. If you have a particular ACM you would like to hear more about or would like to book in an Asbestos Awareness
course please let us know..
Loose fill Asbestos Insulation
Asbestos was generally considered an ideal material for almost all types of insulation as it's extremely resistant to heat, and the air between the mineral fibres slows down the transfer of heat through the material. The naturally occurring mineral has a unique fibrous nature that allows it to take on a fluffy cotton-like consistency.
Loose-fill asbestos is simply raw, crushed asbestos which was commonly used for ceiling insulation. It was designed to be poured into ceiling spaces, under floors or blown into hollow spaces inside walls and other building structures. Fluffy loose-fill asbestos insulation is considered dangerous and extremely friable because even a slight air current can disturb it, sending respirable asbestos fibres into the air. While this type of insulation was more popular in Australia than New Zealand, there is some risk in properties built during the second half of the twentieth century.
