Fibre Cement Texture Base Sheet is an autoclaved,cellulose fibre reinforced cement sheet.

Texture Base Sheet is light blue in colour and features a recess on three edges which enables concealed joint construction.

Once installed a proprietary coating system can be applied to provide a seamless finish that is weatherproof, strong and durable. Refer to jointing and coating systems.

Applications.

Fibre Cement Texture Base Sheet provides a solid substrate for applied decorative finishes.

Our substrate system combined with a proprietary jointing and coating system is suitable as a wall cladding for new homes, recladding of existing homes, extensions, upper storey additions and light commercial applications using domestic construction techniques.

Fibre Cement Texture Base Sheet may be fixed to timber or steel framing to a maximum of two storeys high. For other applications please contact the CSR Building Materials Office in your state.

Design Considerations.

Framing

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

Timber with an equilibrium moisture content of less than 16% at the time of cladding application must be used. Unseasoned timber prone to shrinkage must not be used.

Metal framing must comply with AS3623 -1993 Domestic Metal Framing. When metal framing is used in cold climates and clad with Fibre Cement Texture Base Sheet, insulating materials may be required to prevent thermal bridging.

Fibre Cement Texture Base Sheet when fixed in accordance with this information provides type 'A' bracing. For further details refer to the CSR Fibre Cement Bracing Systems brochure.

Control Joints

Control joints are to be provided in walls at maximum 7.2 metres spacing.

Relief joints are required in two storey construction to allow for shrinkage of deep section floor joists.

For construction of control and relief joints refer to Installation Detail.

Freeze/Thaw Conditions

Where product is to be used in conditions of freeze/thaw please refer to your CSR Building Materials State Office for recommendations.

High Wind Areas

Specific design is required in high wind and cyclonic areas, and your CSR Building Materials State Office should be contacted for further information.

Sheet Preparation. (see Wet Area Lining information)

Framing.

It is important to inspect the frame carefully for bowed, warped, or twisted studs, and for alignment of all framing members. Ensure all timbers are flush.

Studs must have a minimum fixing face width of 38mm, and be spaced at maximum 600mm centres to ensure they match sheet widths. Noggings are to be placed between all studs at maximum 1350mm centres. Ensure all noggings are flush.

Sheets may be fixed vertically or horizontally. If sheets are to be fixed horizontally, noggings must be positioned directly behind all sheet joints, and all sheet edges must be supported by framing members.

Correct design of the framework and careful consideration of the sheet layout to minimise joints will contribute to the long term success of the jointed wall system.

Insulation.

Insulation materials should be installed to enhance thermal insulation properties and occupant comfort. Insulation also improves the acoustic performance of the wall against outside noise.

Where occupant comfort is a consideration, the minimum recommendation is a reflective foil fixed to the outside of the frame, directly beneath the sheets. It is important that a vapour permeable foil be used.

Where greater thermal insulation properties are required, it is recommended that Wall Batts be installed in the wall framing. Check with local building regulations for minimum insulation requirements.

When Wall Batts are installed, it is essential to use a vapour barrier. However to reduce overall costs, building paper such as Thermokraft may be used instead of Breather Foil Antiglare (799).

Light compression of insulation materials is acceptable. Over compression may distort the plasterboard lining.
