Maximum nail spacing using 2.8 mm galvanised clouts or flat head nails. Its thermal resistance is essentially the same regardless of the direction of heat flow through it. Add insulation batts between the studs, ensuring they are fit for the wall-frame thickness to avoid compression, and ensure no gaps are left. Methods of testing sheet roof and wall cladding, Method 2: Resistance to wind pressures for non-cyclone regions. This R value needs to be supplemented with additional insulation.

In all other cases, fixings must be hot-dipped galvanised (min. Every new home built or renovated must undergo a BAL (Bushfire Attack Level) assessment. However, some insulation can be hard to retrofit in later renovations. This ensures that condensation does not present a risk to building occupants. Sarking-type material means a material such as a reflective insulation or other flexible membrane of a type normally used for a purpose such as waterproofing, vapour management or thermal reflectance. Cladding systems consist of 2 interacting components: the wall system (for example, lightweight timber framing) and the cladding layers. Compliance with the new Australian Standard is mandatory for all new building projects. Total R value describe the total resistance to heat flow provided by a roof and ceiling assembly, a wall or a floor. The National Construction Code (NCC) has specific requirements for sound attenuation in multi-unit dwellings which can be satisfied by providing 2 leaves of 110mm clay bricks with a cavity of 50mm between leaves and a 13mm cement render on each outside surface.
