Battens 50 mm (2.0 in) wide × 8 mm (0.31 in) thick, used to cover the joints in fibro sheets. "Super Six" corrugated roof sheeting and fencing. Internal wet area sheeting, "Tilux". Pipes of various sizes for water reticulation and drainage. Drainage pipes tend to be made of pitch fibre, with asbestos cement added to strengthen. [9]
