Company: James Hardie
James Hardie has a range of external cladding products which are suitable for use where non-combustible cladding materials are required as per section 5.8.1 of Acceptable Solutions of ‘Protection from Fire’ Clause-C of NZBC in high density design.
Cladding solutions such as Scyon Linea Weatherboard, Scyon Stria Cladding, Scyon Axon Panel or Titan Façade Panel with coating thickness of less than 1mm, are suitable when designing fire resistant systems for use in multiple tenancy occupation in a building or when close to boundaries.
Another solution to consider is when James Hardie RAB Board is used in lieu of a building underlay in a James Hardie fire rated system, then the published fire rating can be achieved without relying on the cladding product.
The range of James Hardie claddings 6mm or thicker are suitable for use in fire rated wall systems, with a range of interior linings suitable for sound-insulated walls that are suitable for use in apartments, hotels, motels and similar accommodation.
James Hardie internal lining products have the material ‘Group Number’ of 1-S or 1 when tested as per ISO9705 (e.g. Rawform, HardieGlaze & Horizon have a Group Number 1-S and Villaboard and HardieGroove have a Group Number 1). Villaboard lining is not only suitable for use in internal fire rated and acoustic rated walls, it can also be used to achieve bracing where required, providing significant bracing strength immediately after the installation.
The James Hardie Fire & Acoustic Design Manual is intended to assist designers in selecting a suitable system which will meet their performance requirements. Download a copy of the James Hardie Fire & Acoustic Design Manual.
