Roofing Products

There are many product options which will provide passive ventilation for new build and existing homes. As this is a relatively new concept to New Zealand, we have recommended the following range of product options as a simple and effective guideline.

The products have been selected to achieve the recommended airflow for roof pitches above 15° (10,000mm2 lin/m) and below 15° (25,000 mm2 lin/m).

Ventilated Batten – VB20

The VB20 is a Polypropylene Ventilated Batten that not only provides a thermal break but also a moisture barrier between the external cladding and the framework of the building.

The VB20 is designed to provide a strong, durable cavity batten enabling passive airflow around the entire building envelope. One important factor is that it has been designed with the recommended 4mm vents which will repel the movement of nesting insects which can be a common occurrence in cavities.
