Technical Documentation

The VENT Systems Vented Batten – VB20 is a strong, durable roof batten cavity batten that is designed to ensure that unimpeded airflow is guaranteed through the roof cavity of cathedral roof designs, enabling 16,000mm² per linear metre of airflow throughout the entire roof cavity.

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 come with an adhesive underside for ease of temporary fixings to metal or timber framing or battens.

The VB20 can also be used on walls to create vertical or horizontal ventilation flows.

Due to the design of the VB20 it can be easily reduced to create a 15mm or 10mm cavity batten. For every 5mm reduced the airflow rate will reduce by 4,00omm² per linear metre.

The VB20 should be used in conjunction with other specified VENT System products to create a calculated, continuous and unimpeded airflow system.
