Asbestos cladding - Fibrolite, Hardiflex, Super Six, Coverline, Highline, Durock, Poilite, and Hardiplank. Asbestos was in widespread use in New Zealand houses and commercial buildings from the 1940s to the 1990s. It was commonly used in wall or roof cladding, for insulation (both thermal and acoustic), soffit linings, as backing to vinyl flooring and in decorative plaster and textured ceilings.
You may come into contact with it if you are removing or replacing certain types of roof tiles, wall claddings, vinyl floor coverings, sprayed fire protection, decorative ceilings and roofing membranes.
Expect asbestos products in homes build between 1940 and 1990. Professional lab testing is the only way to be sure a product contains asbestos.
