Metra Panel's Inter-Tenancy Wall System is constructed to provide structural support and both fire and sound insulation between habitable spaces from one dwelling to another. Suitable for apartment construction, the Metra Inter-tenancy Wall options comprise two different installation methods to achieve the desired sound insulation result, depending on each project's requirement.
One of the thinnest systems with 130mm and 172mm width options, the system is constructed to provide structural support, a 30/30/30 FRR and sound insulation ratings of either STC57 or STC61, whilst offering more overall floor space for projects for the same size building footprint. Proprietary linings can be eliminated and through clever design, plastering may not even be needed due to the larger panel size.
Option One (Standard)
Sound transmission: STC57
Installation Method: Double 18mm panel / 58mm gap / Double 18mm panel
Sound transmission: STC61
Installation Method: 36mm panel / 100mm gap / Double 18mm panel
When integrated with the entire METRAwalls, floor and ceiling system, Metra Panel Inter-tenancy Wall system is suitable for multi-unit developments.
The STC61 Metra Inter-tenancy Wall Design and Construction boasts a FRR 30/30/30 fire resistance rating and STC61 sound insulation, which can achieve a 1S Fire Rating classification for the NZBC and 1 for the NCC upon application of additional specified Resene coating.
