ProctorVent Drainage Batten (DB-FR)

Product Description

The ProctorPassive Drainage Batten (DB-FR) is a high compressive strength drainage batten manufactured from a polyolefin extrusion.

Product Options

Two types of ProctorPassive (DB-FR) are available. Both products have been tested to AS1530.3 as per the requirements of Specification C1.10 (7) of the NCC 2019.

Proctor Passive DB-FR

The original ProctorPassive DB-FR is made from an intumescent polyolefin extrusion. When exposed to fire, the intumescent in the batten starts to swell and forms a char layer slowing down any melting or spread of flame along the batten. Note that unlike an intumescent ventilated cavity barrier the DB-FR-INT is not designed with sufficient intumescent to fully close off the opening. For such requirements we suggest DCT Tenmat Ventilated Cavity Barriers.

Applications – Roofing

It is common industry practice with metal roofing to install sarking running up the roof fixed on top of 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.

ProctorPassive 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.

Applications – Walls

The ProctorPassive DB-FR can be used either in combination with, or as an alternative to wall battens, to create a ventilation and drainage cavity behind the wall cladding.

As the ProctorPassive DB-FR is open to air movement and drainage, it is well suited for use horizontally or vertically above and below windows where solid battens can potentially block ventilation and drainage.
