In Bush Fire Attack Level (BAL) areas, the Australian Standard limits the use of PVC exposed above the roofline.  The minimal test to BAL12.5 has shown that temperatures can reach 160°C, this far exceeds the melting point of PVC of 85°C.  With the risk of PVC melting, it has the potential of exposing a gap greater than 3mm making it non-compliant to the Australian Standard AS 3959:2018.

Our BAL rated ‘Drainage Vent & Flashing Kit’ comes with a ‘50mm Steel Corrosion Resistant Pipe’ with an integrated ‘Steel Mesh Cowl’ that complies to the requirements of the Australian Standard AS 3959:2018.  

Under the roofline, the ‘Insulated PVC Adaptor’ has been created to withstand any heat transfer when adapted to the 50mm PVC pipe below.
