Fibrolite was used as wall or eaves lining. This is fibre cement sheeting with asbestos as the binding fibre that was used in residential construction until around 1988. In early years it was mostly used for eaves lining, or the sheet cladding to garages. Fibre cement has not contained asbestos since then. It contains the less durable cellulose from wood pulp instead. Fibrolite can be recognised as having a dimpled back surface, rather than the smoother rear surface of a cellulose based product that replaced it.
