Section J1.2 is a general provision and does not explicitly set minimum performance requirements directly. Instead, it sets out testing, installation and calculation criteria related to the thermal performance of the building envelope.
For example, it set’s forth insulation testing requirements against the latest versions of AS/NZS 4859.1 - Thermal insulation materials for buildings (Part 1: General criteria and technical provisions), and AS/NZS 4859.2 - Thermal insulation materials for buildings (Part 2: Design), but does not stipulate the minimum performance requirements to be met by them.
Minimum Performance is set out in the following Parts:
- J1.3 Roof and ceiling construction
- J1.4 Roof lights
- J1.5 Walls and glazing
- J1.6 Floors
