DriSpace VENT VB10 is a Polypropylene Ventilation and Drainage Batten deigned to facilitate passive airflow and cavity drainage between the roofing underlay or membrane and the roof cladding. VB10 prevents the transfer of dew point from the underside of the roof cladding to the underside of the roofing underlay or membrane.
VB10 10mm Vented Batten is a part of DriSpace vented roof and wall systems and should be used in conjunction with other VENT products to ensure a complete ventilation system:
Additional fixing screw length is required to accommodate 30mm thickness of the VB20+VB10.

Passive Ventilation has been used in Canada, America, the United Kingdom and Europe for almost four decades. By introducing passive ventilation into roofs these countries have significantly reduced internal moisture and prevented what was called 'sick home syndrome'.
More recently in New Zealand, since changes to E3:AS1 1.1.4.b of the New Zealand Building Code in 2014, passive ventilation has become more widely understood and the need to ventilate the uninhabited spaces in a building has been more widely acknowledged. Industry experts BRANZ have endorsed passive ventilation as a necessity in Skillion roof types and have recommended that all roof types are passively ventilated as redundancy to eradicate internal moisture.
The NZMRM is currently revising the Metal Roofing Code of Practice to incorporate ventilation into certain roof design and strongly recommending passive ventilation in all metal roof types.
Since the amendment of E3:AS1 hundreds of New Zealand buildings have incorporated passive ventilation into building design and application, These buildings include MOE school Reroof projects, residential new build and renovations and commercial projects.
Products include DriStud wall and roof underlays, Window Flashing Tape, Vent NZ passive ventilation system and Proctor construction membranes.Product Enquiries
