The ProctorVent Drainage Batten (DB-FR) is a high compressive strength (min. 300kPa) drainage batten manufactured from a fire retardant polyolefin extrusion. It is common industry practice with metal roofing to install sarking running up the roof, fixed above roof battens. Such practice restricts air movement and drainage between the sarking and flat profile or concealed-fix roof cladding. This can also lead to ponding if there is excessive drape in the sarking, or can result in the sarking, if pulled tight, being in direct contact with the roof sheet.

DB-FR has been designed to resolve these issues with a drainage batten to provide for air and vapour movement and a pathway for drainage between the sarking and the roof cladding.

DB-FR allows for vapour permeable membranes to be installed without direct contact to the roof or wall cladding thus reducing localised condensation risk on the interior face of these membranes.

DB-FR reduces conductive heat transfer between the roof or wall cladding and the structure and does not restrict buoyancy induced air flow under the roof sheet.

Common Questions About Ventilation and Drainage Battens

1. What is a Ventilation and Drainage Batten used for?

A Ventilation and Drainage Batten creates a gap between your roof underlay and roof cladding. This helps:

Allow air to flow freely under the roof
Drain away moisture and prevent water pooling
Stop condensation from forming on your roofing membrane
Reduce heat transfer between the roof and structure
Protect against moisture damage and corrosion

It’s designed for both residential and commercial roofing projects.

2. How does the VB10 Ventilation and Drainage Batten work?

The VB10 creates a 10mm air gap between the roofing underlay and metal roof sheets. This separation:

Prevents dew point transfer from the roof to the underlay
Allows moisture to escape instead of getting trapped
Provides 8,000mm² of passive airflow per linear metre
Keeps insects out with 4mm vents

The batten works naturally—no power or mechanical parts needed.

3. Is the Ventilation and Drainage Batten easy to install?

Yes, installation is easy:

Peel-off adhesive backing—no nails or glue required
Manufactured in 1000mm or 1800mm lengths for easy handling
Compatible with both steel and timber framing
Can be walked on during installation (strong and durable)

Most DIY builders and professionals find it quick to install on roof battens.

4. Will the Ventilation and Drainage Batten prevent pests?

Yes. The VB10 features:

Insect-proof design with 4mm vents
Prevents nesting insects from entering roof cavities
Maintains airflow while blocking unwanted entry

This makes it ideal for Australian conditions where insects can be a problem in roof spaces.

5. What types of roofs can use Ventilation and Drainage Battens?

Ventilation and Drainage Battens are suitable for:

Skillion and cathedral roofs
Trussed roofs
Metal roofing systems (Colorbond, corrugated, concealed-fix profiles)
Low-pitch roofs prone to moisture issues
Wall cladding applications

They work with most modern roofing designs and materials.

6. What’s the difference between VB10 and VB20 Ventilation and Drainage Battens?

The main difference is thickness and airflow capacity:

Feature	VB10	VB20
Cavity Height	10mm	20mm
Airflow	8,000mm² per metre	Higher capacity
Best For	Standard ventilation needs	Heavy moisture areas or thicker membranes

Choose VB10 for most residential projects. VB20 is better for high-moisture environments or when extra ventilation is needed.
