The name fibro is short for “fibrous (or fibre) cement sheet”, more commonly called “asbestos cement sheet” or “AC sheet”. It is a building material in which asbestos fibres are used to reinforce thin rigid cement sheets.
Although fibro was used in a number of countries, it was in Australia where its use was the most widespread. Predominantly manufactured and sold by James Hardie & Co. until the mid-1980s, fibro in all its forms was a very popular building material, largely due to its durability. The reinforcing fibres involved were almost always asbestos.
The use of fibro has now been banned in several countries, including Australia itself, due to its asbestos content. Asbestos is directly related to a number of life-threatening diseases including, asbestosis, pleural mesothelioma(lung) and peritoneal mesothelioma (abdomen).
