Fibre Cement Cladding Sheet should be fixed vertically to the frame. Fasteners are to be positioned at 200mm centres along sheet edges and ends, at 300mm centres in the body of the sheet, and are to be applied in accordance with the chosen sheet joining method. Fasteners must be positioned a minimum of 12mm from sheet edges and 50mm from sheet corners.

Fixing to Timber Framing

For timber frame installations, use 2.0mm dia. Fibre Cement Nails, 30mm long for softwood and 25mm long for hardwood. Nail heads may be driven flush.

Fixing to Steel Framing

Fibre Cement sheets are to be fixed to steel frames or furring channels using N 8 x 20mm self embedding head needle point screws, for light gauge frames; and N 8 x 25mm self embedding head drill point screws, for heavy gauge frames. When fixing to steel frames, 6mm thickness sheets must be used.

Hot rolled steel structural sections must be battened out with timber or steel battens before sheets are fastened. Sheets must not be fastened directly to hot rolled steel sections.

PVC H-Mould Joint.

Fix PVC H-Mould to frame at 200mm centres. Slide sheet into the side of the PVC H-Mould which has been fixed to the frame. Fix the sheet centre, top and bottom edges. Slide the next PVC H-Mould onto the other side of the sheet and fasten the mould and the adjacent sheet edge to the frame. NOTE - Only one sheet edge at each joint is fastened directly to the frame. The other sheet edge is not fastened, but is held in place by the PVC H-Mould, to allow for movement.

PVC or Timber Cover Mould Joint

Both sheet edges must be fastened to the frame prior to fixing Cover Moulds. When PVC Cover Mould is used, the hole for the fastener must be predrilled. Cover Mould is then fastened to frame at 200mm centres.

Installation - Ceilings & Eaves.

Ceilings

Ceiling sheets are to be fixed at 200mm centres along sheet edges, and at 300mm centres in the body of the sheet. All sheet edges must be supported. Fasteners must be positioned a minimum of 12mm from the sheet edges and 50mm from sheet corners.

Eaves

Support edges of Fibre Cement Eaves Lining Sheet in fascia board rebate groove. Fix body of sheet to trimmers at 300mm centres. Where sheet edges are not supported in a fascia board, fasten sheet edges to a supporting member at 200mm centres. All sheet edges must be supported.

Fasteners must be positioned a minimum of 12mm from the sheet edges, and 50mm from sheet corners.

Typical Installation Details for Eaves

PVC H-Mould.

Sheet ends are joined using a PVC H-Mould. These joins do not need to be supported by a trimmer.

Butt Joints

When no jointing strip is used, sheets may be butted together with both sheet edges fastened to the frame. Butt joints must always coincide with and be supported by a framing member.

Decoration.

Fibre Cement sheets should be finished with two coats of exterior grade acrylic paint.

The surface must be clean and dry before application.

In all cases the paint manufacturer's instructions are to be followed.
