Duraliner is a general-purpose fibre cement building board intended for
flush jointing. It has been specially formulated and prepared to meet the
requirements for use in Wet Areas, Internal Linings, Ceilings, a Substrate
for Ceramic Wall Tiles and Fire & Acoustically Rated Internal
In heavy duty commercial applications for wall tiling, fibre cement
sheets are to have a minimum thickness of 9.0mm as per the Australian
Standard AS 3958.11991 "Ceramic Tiles -Guide to Installation".
Duraliner can also be used on external applications, such as soffits,
where it will not be subject to the direct actions of the
Duraliner is manufactured from Portland cement, finely ground silica,
cellulose fibres and water. It is cured in a high-pressure steam autoclave
to create a durable, dimensionally stable product.
Duraliner is manufactured to comply with the requirements of AS 2908.2
Cellulose Cement Products. It is classified as a Type B Category 2 sheet
and is suitable for internal uses.
Duraliner is available with factory machined recesses on the two long
sides and one end, ready for flush jointing.
The sheet face is coated with a green tinted sealant to facilitate
jointing and coating.Fire Resistance
Duraliner has been tested by the CSIRO (Building, Construction and
Engineering Division) in accordance to Australian Standard AS1530.3 -1989;
see report number FNE 7524 (6.0 mm Duraliner) and FNE 7527 (9.0 mm
Duraliner).Handling and storage
Duraliner sheets must be stacked flat, up off the ground and supported
on level bearers.
The sheets must be kept dry, preferably by being stored inside a
building. When stored outdoors they must be protected from the
Care should be taken to avoid damage to the ends, edges and surfaces.
Sheets must be dry prior to being fixed, or painted. Sheets must be
carried on edge.Quality Systems
BGC Fibre Cement manufactures Duraliner under the rigorous Quality
Management System of the International Standard ISO 9002:1994, and is the
holder of Licence Agreement number QEC2955/13.Health Safety
BGC Duraliner is manufactured from cellulose fibre, finely ground sand,
Portland cement and additives. As manufactured the product will not
release airborne dust, but during drilling, cutting and sanding operations
cellulose fibres, silica and calcium silicate dust may be released.
Breathing in fine silica dust is hazardous, prolonged exposure (usually
over several years) may cause bronchitis, silicosis or cancer.Do
not breathe dust
When cutting sheets, work in a well-ventilated area and use the methods
recommended in this literature to minimise dust generation. If using power
tools for cutting, drilling or sanding they must be fitted with
appropriate dust collection devices or the operator should wear an
approved (P1 or P2) dust mask and safety glasses.
These precautions are not necessary when stacking, unloading or
handling fibre cement products.Product Types
Ceramic Tile Floor Underlay – Fibre Cement Substrate for
Ceramic Floor Tiles
BGC Ceramic Tile Floor Underlay is a
specially formulated fibre cement sheet designed to provide a stable
substrate for slate and ceramic floor tiles. It can be installed
over new or existing timber floorboards, plywood or particleboard
In dry areas, tiling may be applied directly to the BGC
Ceramic Tile Floor Underlay to form an impervious, easily cleaned
For wet areas, and areas subject to accidental flooding
or water splash, the installation of a waterproof membrane between
the BGC Ceramic Tile Floor Underlay and the tiling is
Vinyl & Cork Underlay – Fibre Cement Substrate for Vinyl
& Cork Floor Coverings
BGC Vinyl and Cork Underlay sheets
have been designed, tested and manufactured to provide a smooth,
durable and completely termite and rodent proof surface on which to
lay vinyl & cork tiles. The sheets are also immune to water
damage and will not swell. Vinyl and Cork Underlay sheets can also
be used under parquetry floor tiles.
