VB10 —Ventilation and Drainage Roof Batten
Description

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. 

Key Features
  • Convenient peel-off adhesive backing eliminates the need for nails or glue
  • Insect proof — 4mm vents prevent ingress of nesting insects
  • Provides passive airflow of 8,000mm² per linear metre
  • Easy to install — manufactured in 1800mm lengths for easy handling
  • Strong and durable — when used as a vented batten on top of roofing battens, the VENT VB10 has been upgraded in strength and tested to exceed foot traffic weight requirements on the roof above
Scope of Use
  • Recommended for skillion and trussed roofs
  • Highly recommended for roofs with cladding profiles with a large area of surface contact with roofing underlays i.e. trapezoidal or deep trough profiles
  • Commercial and residential application
  • To be used as part of proprietary DriSpace ventilation system
Limitations on Use

In-Service History

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.
