• with a building height not exceeding 25 m; and,
• constructed with timber framing subject to specific engineering design; and,
• situated in specific design wind pressures up to a maximum design differential ultimate limit state (ULS) of 3.2 kPa where studs are at maximum 600 mm centres; and,
• with inter-storey deflections designed for and up to height/180 of horizontal in-plane movement during seismic serviceable limit state (SLS) events (based on a 3 m inter-storey height); and,
• when fixed over James Hardie RAB™ Board rigid air barrier for buildings over 10 m in height.

3. Oblique™ Weatherboard (Vertical) Cavity Cladding must only be installed vertically on vertical, flat surfaces.
