Abutment Vent RV10AP-HALF
By cutting the VENT Systems Abutment Vent RV10AP in half the perfect ventilation product for both abutment or mono-pitch barge details.
The VENT Systems Abutment Vent RV10AP-HALF is engineered to expel air from the roof void using natural convection, as warmer air rises, or through negative pressure generated by wind passing over the roof. Featuring an adhesive and flexible aluminum flashing, the RV10AP-HALF conforms to various roofing profiles, effectively preventing water ingress. It’s designed to be compatible with roof cladding profiles having a trough depth of 34mm or greater.
This product ensures compliance with the National Construction Code 2022 Vol 1: F8D5/ABCB Housing Provisions Standard 10.8.3.
The RV10AP-HALF operates year-round without requiring any moving parts or energy consumption. Serving as a discreet alternative to traditional rotary-driven (whirlybird) vents, the RV10AP-HALF doesn’t necessitate roof cladding penetration and is concealed by ridge capping or flashings upon installation.
It’s strongly recommended to incorporate high-level vents with some form of Over Fascia or Eaves ventilation for optimal performance.
Please note that the Metal ridge cap is supplied by the roof cladding supplier.

NOTE: For standing seam or trapezoidal profiles ‘snipping’ or ‘crimping’ may be required. For roof cladding profiles with a trough depth below 34mm the RV10AP-HALF is designed to be compatible with most cladding profiles
For application in BAL zones, the RV10AP-HALF can be enhanced with an ember guard crafted from non-combustible, corrosion-resistant materials such as steel, bronze, or aluminum mesh, ensuring maximum safety. The mesh aperture conforms to Clause 3.6 of AS3959:2018, with a maximum allowable opening of 2 mm.
VENT Systems specialises in ventilation and internal moisture management. Any guidance regarding the RV10AP and its ember guard should be considered alongside the latest version of AS3959, the National Construction Code, and any local regulations. It’s essential to collaborate with building certifiers, fire engineers, or specialised bush fire consultants to ensure compliance and safety in all applications.
