Description.
Fibre Cement Wallboard is an autoclaved, cellulose fibre reinforced cement sheet which is immune to water damage and will not rot.
Fibre Cement Wallboard is designed specifically for use in the lining of walls in kitchens, bathrooms, laundries, toilets and other areas commonly known as 'wet areas' in domestic buildings.
Fibre Cement Wallboard has a recess on both long edges so that sheets may be taped and set with plasterboard jointing materials.
Fibre Cement Wallboard, once jointed, may be tiled, painted or wallpapered as desired.

Advantages
- Simple and quick to install.
- Low installed cost.
- Immune to water damage.
- Smooth sanded finish.
- Maintenance free.
- A suitable substrate for all forms of decorative finishing.
Applications
Australian Standard AS3740 - 1994 'Waterproofing of wet areas within residential buildings' defines wet areas in two categories.
Category 1 - Wet Areas; are the wall and floor areas enclosing a shower compartment, i.e. part wall areas of showers within bathrooms and ensuites.
Category 2 - Wet Areas; are the part walls adjacent to fixed vessels such as baths, toilets and tubs, i.e. part wall areas within bathrooms, ensuites, laundries and kitchens other than the wall area enclosing a shower.
CATEGORY 1. Shower Recess Areas
Fibre Cement Wallboard is used in Category 1 areas as a substrate for ceramic tiles, and must be fastened with nails or screws.
Wallboard sheets are then jointed with Base Coat 100 or 120 and paper tape.
CATEGORY 2. General Wet Areas.
Fibre Cement Wallboard is installed into these areas in the same manner as for standard plasterboard.
Wall sheets to be used as a substrate for tiling must be fixed with nails or screws only.
Fire Resistance
Fibre Cement Wallboard is deemed to be non-combustible in terms of the Building Code of Australia.
It has excellent Early Fire Hazard properties.
Early Fire Hazard Indices:
- Ignitability 0
- Spread of Flame 0
- Heat Evolved 0
- Smoke Developed 0
Control Joints
Control joints are to be installed in large spans of wall to allow for structural movement, and are to be positioned:
- In non tiled areas at
not more than 7.2m
spacings.
- In tiled areas at not
more than 4.2m spacings.
Control joints are to be
constructed with a double
stud, and allowance for
expansion/contraction is
to be made in both the
wallboard and tiles.
These methods are
recommended.
