Fibre Cement Cladding Sheet and Fibre Cement Eaves Lining Sheets are autoclaved, cellulose fibre reinforced cement sheets with a smooth flat surface. They are immune to water damage and will not rot.

Applications

Fibre Cement Cladding Sheets are designed for use as external wall claddings, lining of verandahs and soffits, gable ends, garages and upper storey additions.

High Wind Areas

The systems in this information are designed for non cyclonic regions. For high wind and cyclonic areas, closer framing centres will be required. Contact CSR Building Materials State Office for further information.

Advantages

• Smooth surface finish on face of sheet easily accepts popular exterior paint finishes.
• Simple and quick to install using standard building methods.
• Immune to water permanent damage and will not rot.
• Maintenance free.
• High durability exterior grade material.
• Fire resistant and non combustible.
• Termite proof.

Support Framing

Fibre Cement Cladding and Eaves Lining Sheets may be fixed to timber or steel frames which satisfy local government building regulations.

Timber framing must comply with AS1684-1992 National Timber Framing Code.

Metal framing must comply with AS3623-1993 Domestic Metal Framing.

Joints between Cladding Sheets should always coincide with a supporting framing member. To provide suffient support for nails or screws, aluminium stud width of 35mm is required.

Where this is not possible, an additional stud or trimmer will be required to ensure fasteners can be fixed at a minimum distance of 12mm from the sheet edge.

Insulation

Insulation materials should be installed to enhance thermal insulation properties and occupant comfort. Insulation also acts as an additional barrier against wind, dust, rain and noise. Depending on the level of thermal insulation required, two alternatives are recommended.

The minimum recommendation is to install a reflective foil fixed to the outside of the frame. It is important that a vapour permeable foil be used. The correct installation ot this foil will provide an insulation rating of approximately R0.6.

Where greater thermal insulation properties are important, it is recommended that fibreglass Batts be installed in the wall framing. Requirements will vary from region to region, but Gold Batts are available with insulation ratings of up to R2.0.

When glasswool insulation is installed, it is essential to use a vapour barrier.
