The VENT Systems Ventilation & Drainage Batten 10mm VB10 is a Polypropylene batten designed to facilitate passive airflow and cavity drainage between the roofing underlay or membrane and the Colorbond roof cladding.

The VB10 creates a 10mm separation gap between the Colorbond roof and the vapour permeable membrane, preventing the transfer of dew point from the underside of the Colorbond roof to the underside of the roofing underlay or membrane.

The VB10 can be used to establish a 10mm ventilation and drainage cavity behind lightweight wall claddings.
