VENT Systems Wall Cavity Batten – VB20

The VENT Systems Wall Cavity Batten – VB20 is a Polypropylene batten that is the ideal product to create a 20mm cavity for ventilation and drainage in walls for both residential and commercial buildings, as specified by NZBC Acceptable Solution E2/AS1, Paragraph 9.1.8.2. Due to the design of the VB20 it can be installed continuously in horizontal or vertical positions. With no temporary fixings required the is both effective and efficient.

Due to the design of the VB20 it can be easily reduced to create a 15mm or 10mm cavity batten.

When installed horizontally and continuously, the VB20 provide vermin proofing to the bottom of the drained cavity. If a durable life of more than 15 years is required, vermin proofing must be installed at the base of the cavity.

When installed vertically or for non-continuous horizontal installations, the VB20 do not provide vermin proofing to the bottom of the drained cavity. A cavity vent strip complying with NZBC Acceptable Solution E2/AS1, Paragraph 9.1.8.3 must be installed as part of the selected cladding system.
