6.6 CAVITY BATTEN

Figure 4 Cavity Batten



9 FIXING DETAILS FOR WEATHERBOARD

9.1.1 BC-105 - PAINT FINISH WITH STRUCTURAL CAVITY BATTENS

Figure 5 BC-105, Fixing Detail for Painted Weatherboard with Structural Cavity Battens

Note: Although a 75 x 4.0mm jolt head nail is shown (achieving 35mm framing penetration), a smaller 65 x 3.15mm nail may be used if it is annular grooved (which only needs to achieve a 25mm framing penetration).



9.1.1 BC-106 - PAINTED WEATHERBOARDS STANDARD CAVITY FIX

Figure 6 BC-106, Fixing Detail for Painted Weatherboard with a standard cavity fix

Jolt head nails to be hard driven and punched just below the surface of the weatherboard, spot primed, and filled and anded smooth. Pilot drill all nail holes using a 2mm diameter drill bit.



9.1.2 BC-107 - STAIN OR BARE FINISH WITH STRUCTURAL CAVITY BATTENS

Figure 7 BC-107, Fixing Detail for Stain or Bare Weatherboard with structural cavity battens

When nailing rose head or pentagon head nails on an upward angle, care should be taken to ensure the nail finished flush onto, but not into or below the surface of the weatherboards.



9.1.2 BC-107 - STAINED OR BARE FINISH WITH PACKER CAVITY BATTENS

Figure 8 BC-108, Fixing Detail for Stained or Bare Finish with packer cavity battens

Care must be taken when nailing rose head or pentagon head nails, they must be hand driven, and finished flush onto and not into the face of the weatherboards. Too much force will damage the face of the timber.

Pilot drill all nail holes with a drill bit that is 1mm less than the diameter of the nail shank to ensure a snug fit and reduce the risk of the timber splitting.

17.3. BC-703 – INSTALLATION

1: Cover the framed wall with building Underlay.

2: Frame the balustrade/parapet.

3: Cover the balustrade/parapet with building Underlay ensuring that’s its one continuous piece. Apply flashing tape to join balustrade and wall underlay.

4: Apply battens to wall. 5: Apply cavity battens to

balustrade/parapet. 6: Installation of sloped packer with flexible flashing tape dressed onto main wall underlay and applied 50mm down face of balustrade.



7: Fit corner flashings to corners.

8: Fix lower weatherboards to balustrade/parapet

9: Scribe and notch weatherboards on the wall to the weatherboards on the balustrade/parapet.

10: Fix weatherboards to balustrade/parapet.

Continue to scribe and notch weatherboards on the wall to the balustrade/parapet.

12: Fit triangular packers to top of balustrade/parapet to give a solid surface for capping.



13: Install an isolating layer of roofing underlay between timber and metal flashing in preparation for installing capping.

14: Install saddle flashing. 15: Apply two lines of sealant to saddle capping flashing.

16: Install capping, and seal to saddle flashing by riveting and using two lines of sealant. Fix lower weatherboards to wall.

17: Scribe weatherboards to fit over and around saddle flashing.

18: Install rest of weatherboards.



13: Install capping, and seal to saddle flashing by riveting and using two lines of sealant.

14: Fix lower weatherboards to wall.

15: Scribe weatherboards to fit over and around saddle flashing.

16: Install rest of weatherboards.
