Product combinations are essential to achieve Calculated, continuous, unimpeded passive ventilation

There are a variety of product options & combinations which will provide passive ventilation for new build and existing homes. It is imperative products are used in combination as recommended in VENT Systems technical details to ensure that calculated, continuous, unimpeded airflow is achieved.

VENT OVER FASCIA VENT – G1200N

The VENT Systems Over Fascia Vent – G1200N is the most practical and cost efficient method of ventilating the Eaves. It is easy to install, discrete and is compatible with either timber of metal fascias.

VENT OVER FASCIA VENT – G2500N

The VENT Over Fascia Vent – G2500N is the most practical and cost efficient method of ventilating the Eaves. It is easy to install, discrete and is compatible with either timber of metal fascias.

VENT EVES COMB FILLER – G1275

The G1275 VENT Systems Eaves Comb Filler is designed with flexible fingers that adjust to fill the gaps left when using profiled tiles or steel roof cladding, preventing entry of birds and large insects.

VENT ROLL PANEL VENT – G502

​The VENT Systems Roll Panel Vent – G502 is designed to maintain a continuous 25mm air gap between the underside of the roofing membrane or sarking and loft insulation at the eaves, providing a consistent flow of air into the roof space.

VENT VENTED BATTEN – VB20

The VENT Systems Vented Batten – VB20 is a strong, durable roof batten cavity batten that is designed to ensure that unimpeded airflow is guaranteed through the roof cavity of cathedral roof designs, enabling 16,000mm² per linear metre of airflow throughout the entire roof cavity.

VENT RIDGE VENT – RV10P

The VENT Ridge Vent – RV10P is designed to release warm air from the roof void using the natural convection of rising warm air and by means of negative pressure created by wind blowing over the roof. The RV10P releases airflow of 8,000mm² per linear metre. The RV10P has an adhesive and flexible aluminium flashing which is designed to form to roofing profiles and prevent water ingress on any pitch roof.

RIDGE VENT DEEP TROUGH – RV10DT

The VENT Ridge Vent Deep Trough – RV10DT is designed to release warm air from the roof void using the natural convection of rising warm air or by means of negative pressure created by wind blowing over the roof. The RV10DT releases airflow of 8,000mm² per linear metre. The RV10DT has an adhesive and flexible aluminium flashing which is designed to form to roofing profiles and prevent water ingress on any pitch roof.

APRON VENT – RV10P Half

Using half a VENT Systems Ridge Vent  – RV10P Half,  an Apron or Abutment vent is created that is designed to release warm air from the lower roof void or through the barge detail of a mono pitch cathedral roof, using the natural convection of rising warm air or by means of negative pressure created by wind blowing over the roof. The RV10P Half release airflow of 8,000mm² per linear metre. The  RV10P Half has an adhesive and flexible aluminium flashing which is designed to form to roofing profiles and prevent water ingress on any pitch roof.

APRON VENT DEEP TROUGH – RV10DT Half

Using half a VENT Systems Ridge Vent  – RV10DT Half,  an Apron or Abutment vent is created that is designed to designed to release warm air from the lower roof void or through the barge detail of a mono pitch cathedral roof, using the natural convection of rising warm air or by means of negative pressure created by wind blowing over the roof. The RV10DT Half releases airflow of 8,000mm² per linear metre. The RV10DT Half has an adhesive and flexible aluminium flashing which is designed to form to roofing profiles and prevent water ingress on any pitch roof.

VENT CIRCULAR SOFFIT VENT – G700

The VENT Systems Circular Soffit Vent – G700 Vents can be utilised for new build & refurbishment projects. The G700s are an easy retro fit solution for existing soffits on both Cathedral and Traditional roof designs. Standard fixing for this product is a simple push twist action into a 70mm hole drilled in the soffit board.

VB20 Wall Cavity Batten

The VENT Systems Wall Cavity Batten – VB20 is a Polypropylene batten that is the ideal product to create a 20mm cavity for ventilation and drainage in walls for both residential and commercial buildings, as specified by NZBC Acceptable Solution E2/AS1, Paragraph 9.1.8.2. Due to the design of the VB20 it can be installed continuously in horizontal or vertical positions. With no temporary fixings required the is both effective and efficient.
