BAL12.5 Rated Drainage Vent & Flashing Kit – 50 mm Steel Pipe + EPDM Flashing (Bushfire Zone Compliant)
BAL12.5 Rated Drainage Vent & Flashing Kit – 50 mm Steel Pipe + EPDM Flashing (Bushfire Zone Compliant)
Ensure reliable, bush-fire-resistant venting with the BAL12.5 Rated Drainage Vent & Flashing Kit — a complete solution engineered for roof-penetrating drainage vents in BAL (Bushfire Attack Level) zones across Australia.
Key Features & Benefits:
-
Purpose-built for PVC vent pipes that extend above the roof line in BAL-rated areas.
-
Includes premium 50 mm corrosion-resistant steel vent pipe with an integrated steel mesh cowl, preventing embers and debris from entering.
-
Comes with a BAL-rated EPDM pipe flashing designed for metal roofing, offering exceptional durability and heat resistance.
-
Includes a steel-to-PVC insulated adaptor, ensuring safe transition from steel vent to underlying PVC pipe and minimising heat transfer.
-
Fully compliant with AS 3959:2018 — critical in BAL 12.5 zones where pipe surface temperatures can reach ~160 °C, well above the melting point of PVC (~85 °C).
-
Ideal for residential and commercial installations in BAL 12.5 environments, giving builders, plumbers and roofers confidence and compliance.
What’s Inside the Kit:
-
50 mm steel vent pipe with mesh cowl
-
BAL-rated EPDM flashing for metal roofs
-
Insulated steel-to-PVC adaptor
Why Choose This Kit:
When mounting drainage vent pipes through roofs in bush-fire-prone zones, you need a solution that goes beyond standard fittings. This kit integrates metal and EPDM components to tackle heat, embers and fire risk — delivering peace of mind and regulatory compliance in one box.
Applications:
-
Roof plumbing vents in BAL 12.5 constructions
-
Commercial or residential roofs requiring bush-fire rated penetrations
-
Replacement or new-build installations where fire-resistance is mandated
Installation Note:
Ensure flashing is installed as per manufacturer guidelines, with correct sealing at roof interface and pipe adaptor connection. The steel pipe must extend above the roof line and mesh cowl positioned to reduce ember ingress.
