Save Time with VENT’s BRANZ Appraised Wall Cavity

The VENT VB20 has been used as a vented roof batten on hundreds of residential and commercial projects across New Zealand. Following growing demand from architects and installers to use the batten in wall applications, VENT has now had the VB20 BRANZ appraised for use as a wall cavity batten.

“As specifiers and installers became aware of the significant advantages of using VENT's VB20, we saw an increase in requests of whether it can be used as wall cavity batten,” explains James Johnston, VENT. “With the BRANZ appraisal, we’re now giving specifiers a new choice of cavity batten for walls.”

Providing a new option for ventilating wall cavities, the VENT VB20 offers numerous advantages:

Time-saving peel-and-apply installation

The VENT VB20 Wall Cavity Batten comes with an adhesive strip, allowing for fast and easy fixing to timber, building wraps and steel framing. This eliminates the need for glues and nails and means temporary fixing is not required.

Durability

Designed with 4mm spacings, the VB20 Wall Cavity Batten is suitable for use as a cavity closer on projects that need to meet NZBC durability requirements of up to 15 years, meeting NZBC durability requirements.

Adaptable to meet project requirements

The unique design and make-up of the VB20 means it can easily be split on site to create 15mm or 10mm cavities where needed.

The VB20 Wall Cavity Batten has already been specified on several projects nationwide. The performance and installation advantages of the VB20 were recognised by the Ministry of Education who have specified the wall cavity batten for their portable classrooms. With VENT already supplying roof ventilation systems for the classrooms, this means the Ministry can rely on a single supplier for both roof and wall battens. “We’ve created a one-stop-shop with the wall cavity batten and roof ventilation batten supplied as the one system,” says James.

VENT’s BRANZ appraised solutions and expertise in roof and wall ventilation make them the perfect partner for designing healthy buildings.

VENT products are now distributed in New Zealand by DriStud, a division of TCL Hunt.
