Triboard Inter-tenancy Wall Systems are fire-rated and sound insulating walls based on Triboard panels.
The Triboard Inter-tenancy Wall System has been appraised for use as load bearing or non-load bearing, fire-rated and sound insulating internal walls.
The walls must be straight. The maximum height allowed for any single storey of a Triboard Inter-tenancy Wall System is 3.0 m for loaded walls and 4.5 m for unloaded walls. For loaded walls the maximum allowable design load is 20 kN/m of wall length. For loaded wall heights greater than 3.0 m specific design is required. This is outside the scope of this Appraisal.
The Triboard Inter-tenancy Wall System is suitable for use when interfacing with traditional timber frame construction, light gauge steel frame construction, and with the Triboard Construction System. See Paragraph 7.1.
The Triboard Inter-tenancy Wall System is suitable for use as infill panels within buildings having concrete frames designed to NZS 3101.
The use of Triboard wall panels in the following situations has not been assessed and is outside the scope of this Appraisal:
- sauna rooms and the like where they may be exposed to sustained high humidity (greater than 95% RH) or liquid water.
- where temperatures are in excess of 35C over large areas for prolonged periods or in excess of 50C in localised areas (e.g. the area adjacent to a fuel burning appliance).
