Vent 3 Pro membrane is a high-performance, triple-layer breathable membrane, manufactured from flexible polypropylene sheets fused with a micro-porous core. Suitable for use behind both supported and unsupported structural cladding, it’s ideal for composite and fibre cement cladding projects alike. It can also be used on roofing projects.
Designed to allow structures to breathe, the membrane resists water ingress while enabling trapped moisture and vapour to escape, helping to minimise the risk of damp within the wall system.

The combination of durability and water-resistant properties makes the membrane suitable for use in both cold and warm areas. It can also be installed directly on top of insulation materials to effectively prevent wind-driven rain, snow and dust from penetrating outdoor cladding systems.
When integrated into cladding structures, Vent 3 Pro supports proper airflow behind the cladding panels, improving overall system performance and helping maintain a healthy building envelope.
Combined with suitable trims and fixings, it forms part of a cost-effective and durable cladding solution.
