Australian Standard AS 4256.4 -2006 states the following: Type B cladding shall only be used when fully and continuously supported over structural framing or over existing walling. Classification: Type B cladding is defined as having a transverse bending stiffness less than 1.0 Nm2, in accordance with AS/NZS 4257.9. All foam backed vinyl (PVC) cladding falls into this classification – Type B Cladding This means that for new construction or over new framework, foam backed vinyl cladding must be installed over an underlay to meet Australian Standards. It is also recommended that studwork be built with 450mm centres.
Levelwall acts as an insulation wrap, reducing air infiltration, insulating timber studs and reducing noise transmission. It also provides a smooth, level surface over framework for the application of vinyl cladding, and ensures the cladding is fully and continuously supported, as required by Australian Standards.
