Ventilated Batten – VB20

Our Ventilated Cavity Batten – VB20 Roof, is a strong, durable product designed to ensure that unimpeded airflow through the roof cavity of a cathedral roof design, with 16,000mm² per linear metre open area, enabling passive airflow around the entire building envelope.

The VB20 is designed with 4mm evenly spaced openings specifically sized to prohibit large insects gaining access but wide enough to prevent capillary action. The VB20 is easy to install and comes with self-adhesive backing for ease of temporary fixings to metal or timber roof battens.

The VB20 is to be used in conjunction with other specified Vent Systems products if impeded ventilation through the roof cavity is to be achieved.
