ProctorPassive Drainage Batten (DB-FR)

Product Description

ProctorPassive Intumescent Drainage Batten (DB-FR) is a high compressive strength drainage batten constructed from an intumescent polyolefin extrusion.

Applications

It had become common industry practice with metal roofing to install sarking running up the roof over the roof battens. Such practice restricts air movement and drainage between the sarking and flat profile or concealed-fix roof cladding. This leads to either ponding due to excessive drape in the sarking or sarking in direct contact with the roof sheet when pulled tight. ProctorPassive DB-FR has been designed to resolve these issues using the drainage batten to provide for air and vapour movement and a pathway for drainage between the sarking and the roof cladding.

Installation

Install the sarking, taping overlaps if required, such as on low pitched roofs. When sarking is installed over roof battens/purlins the drape should be minimised to avoid ponding behind battens, but draped sufficiently to manage any shrinkage as declared by the sarking manufacturer.

Concealed-fix roof cladding

Cut the ProctorPassive DB-FR to length and adhere to the underside of the concealed-fix clip. Adhere with a double sided tape or use custom made self adhering ProctorPassive DB-FR.

Direct fix metal roof cladding

Cut the ProctorPassive DB-FR to a manageable length. To keep ProctorPassive DB-FR in position prior to fixing the roof sheet fix or adhere to the sarking, running the full length of each roof batten.

Install the roof sheet as per manufactures instructions leaving a path for drainage and air movement under the roof cladding or concealed-fix clip.
Care must be taken when fixing the cladding not to over compress the ProctorPassive DB-FR. Provided the torque is set at a level that will not to damage the EPDM washers on the roofing screws then a sufficient air gap will be maintained. Sufficient pressure should be applied to the roof sheet when fixing to endure the batten is not lifted from the sarking.

Walls

ProctorPassive DB-FR can be used in wall applications to create a drained and vented cavity behind the cladding. The batten is fixed as required, vertically or horizontally, aligned with studs, noggins, around windows and doors and the top and bottom plates. Cladding must be fixed through the battens into the structural frame as normal.

Benefits

• Provides for a drainage and ventilation path under flat profile and concealed-fix roof and wall claddings.
• Reduces the risk of ponding on sarking behind roof battens and at eaves.
• Allows for sarking to be installed without contact to the roof cladding thus reducing condensation risk under the sarking.
• Reduces conductive heat transfer between the roof and wall cladding and the structure.
• Increases buoyancy induced air flow under the roof sheet and in wall cavities.
• Will not readily melt or spread flame in the event of a fire.
