Roof/upper floor ceiling
| Options | Description of construction |
|---|---|
| 1 | Roof Pitched roof clad with tiles, or not less than 0.5 mm roofing iron, or 6mm corrugated cellulose-cement Ceiling 12.5 mm plasterboard fixed to underside of horizontal ceiling joist or ceiling battens. Insulation Fibre insulation batt or blanket with a thickness of not less than 94 mm and density of not less than 12 kg/m3 (such as Ceiling Pink Batts R2.2 or equivalent), laid between ceiling joists. |
| 2 | Roof Steel trough roofing or other roofing iron, not less than 0.5 mm thick. Ceiling One layer of 12.5 mm thick plasterboard fixed to the same timber framework as the roof but with a separation of not less than 150 mm between the roofing and the plasterboard. Insulation Fibre insulation batt or blanket with a thickness of not less than 94mm and density of not less than 12 kg/m3 (such as Ceiling Pink Batts R2.2 or equivalent), laid between joists or compressed over purlins (can be combined with integral waterproof membrane). |
Notes:
The required degree of insulation will only be provided if the specified level of integrity is maintained throughout the envelope of the building in respect to areas in which sound insulation requirements apply. If a sound transmission path is provided from outside the building to inside the insulated room via a path that is not fully and appropriately insulation against, then the design of the building shall not comply with the permitted activity performance standard.
In determining the insulation performance of roof/ceiling arrangements, roof spaces are assumed to have not more than the casual ventilation typical of the jointing capping and guttering details used in normal construction. Mechanical ventilation of spaces with non opening windows or sound insulated windows should be provided in accordance with provisions of the New Zealand Building Code G4 in a manner which does not compromise sound insulation.
Outer walls
| Options | Description of construction |
| 1 | Contruction Conventional timber stud-framed walls External cladding Not less than 18 mm thick timber weather board; or Not less than 9 mm thick compressed fibre cement sheets; or Not less than 18mm thick solid plaster. Internal lining Not less than 9.5mm thick plasterboard. Cavity insulation Fibre insulation batt or blanket with a thickness of not less than 94mm and density of not less than 12 kg/m3 (such as wall Pink Batts R2.2 or equivalent) |
| 2 | Construction Conventional brick veneer installed in accordance with clearly presented and adequate technical information on installation supplied by the manufacturer. Internal lining Not less than 9.5mm thick plasterboard. |
Notes:
The required degree of insulation will only be provided if the specified level of integrity is maintained throughout the envelope of the building in respect to areas in which sound insulation requirements apply. Is a sound transmission path is provided from outside the building to inside the insulated room in question via a path than is not fully and appropriately insulation against then the design of the building shall not comply with the permitted activity performance standard.
Mechanical ventilation of spaces with non opening windows or sound insulated windows should be provided in accordance with provisions of the New Zealand Building Code G4 in a manner which does not compromise sound insulation.
Outer windows
| Options | Description of construction |
| 1 | Construction Single glass windows in an aluminium, steel, timber or PVC frame with a positive sealing arrangement. Area Up to 50% of the total exterior wall area. Glazing Not less than 6 mm monolithic or laminated glass. |
| 2 | Construction Double glazed or double windows in an aluminium, timber or PVC frame with a positive sealing arrangement. Area Up to 50% of the total exterior wall area. Glazing Two panes of a minimum thickness of 4 mm with an airspace of not less than 6 mm. |
Notes:
The required degree of insulation will only be provided if the specified level of integrity is maintained throughout the envelope of the building in respect to areas in which sound insulation requirements apply. Is a sound transmission path is provided from outside the building to inside the insulated room in question via a path than is not fully and appropriately insulation against then the design of the building shall not comply with the permitted activity performance standard.
Mechanical ventilation of spaces with non opening windows or sound insulated windows should be provided in accordance with provisions of the New Zealand Building Code G4 in a manner which does not compromise sound insulation.
In all cases opening windows are permissible. Where non-opening windows are used, an early warning smoke detection system should be installed and maintained within the premises (particularly in sleeping rooms and exitways) in accordance with an approved New Zealand Code or Standard or AS3786:1993). Where mechanical ventilation is provided devices should be installed to shut down or close off the system to prevent the travel of fire and smoke products.
Outer doors
| Options | Description of construction |
| 1 | Solid core door of a thickness not less than 35 mm and a superficial density of not less than 20 kg/m3 complete with soft gasket around sides and top and drop seal at base. |
