situated in NZS 3604 Building Wind Zones up to, and including ‘Very High’.
This specification also covers the weathertightness and structural wind loading of the Hermpac Bevelback and Rebated Bevelback Weatherboard Cavity System when used on timber framed buildings subject to specific design up to a design differential ultimate limit state (ULS) wind pressure of 2.5 kPa.
For applications which are outside the scope of this literature and details which are not in this literature the specifier must ensure that the design meets the relevant performance requirements of the NZBC.
Herman Pacific Limited recommends that professional design advice is sought in these circumstances.
