BGC PlasterboardBefore commissioning a Plasterboard plant in Australia, BGC researched the world's foremost plasterboard

manufacturing countries, in order to adopt the most advanced production techniques, available today.

BGC Plasterboard is purpose designed as a complete wall and ceiling lining system that conforms to the stringentdemands of regulatory bodies throughout Australia and overseas.

Our highly professional team of engineers and skilled personnel maintain world class plant and equipment at our

Western Australian factory premises and, together with the Company's pursuance of manufacturing excellence,

assures the specifying and building industry of quality BGC Plasterboard products.

As a wholly owned, privately operated Australian company, BGC recognises the importance of product Research and

Development programmes. Continued investment into this disipline ensures BGC will remain a leader in the

manufacturing and supply of quality building products and materials.

BGC Fire-Resistant (FR)Plasterboard Non-Load BearingPartition Systems

IntroductionBGC Plasterboards Fire-Rated Systems, consist of

single or multiple layers of BGC FR Plasterboardsheets, screw-fixed to steel framing and nail or screw

fixed to timber stud framing non-load bearing.

BGC FR Plasterboard is manufactured to the

requirements of Australian Standards AS/NZS

2588:1998 - Gypsum plasterboard and must be

installed in accordance with the Australian Standards

AS/NZS 2589.1:1997 - Gypsum linings in residential

and light commercial construction-application and

finishing. Part 1: Gypsum plasterboard.

BGC FR Plasterboard Fire Rated Systems have beentested AS/NZS 3837: 1998 and AS/NZS 1530.4:

1997, by NATA accredited testing laboratori es.

Test reports and letters of opinion are available on

request from BGC Plasterboard.

BGC FR Plasterboard has a light-pink facing paper-

board for easy identification and is available in 13mm

and 16mm thicknesses with recessed edges, ready for

taping and jointing with proprietary stopping and

setting compounds.

Early Fire Hazard IndicesBGC FR Plasterboard complies with the Building Code

of Australia (BCA) Material Group Number

Classification and Deemed to Satisfy Provisions, as

determined by AS/NZS 3837: 1998 tests.

Material Classification: Group 1.

(BCA) Specification A2.4)

Suitability as Wall and Ceiling Lining In Fire-Isolated

Exits, Public Corridors, Specified and Other Areas.

ApplicationBGC FR Plasterboard wall systems are suitable for

industrial, commercial and residential applications,

both in the new construction and renovation sectors.

Load bearing and non-load bearing walls and partitions

can be clad with single or multiple layers of BGC FR

Plasterboard, with or without cavity infill insulation, to

achieve the required results for fire resistance: FRL

and acoustic properties: RW.

Non-Load Bearing WallsThe maximum wall heights for non-load bearing fire

rated walls, in this Installation Guide are for laterally

loaded walls of 0.25 kPa, as set out in Table 2 and 3

below.

The maximum stud height is based H/240 or 30mm

maximum deflection, to comply with BCA 2004

Specification 1.8 Clause 3.4.

Steel Stud Wall HeightSteel stud walls above 4.2 m in height must have a

single row of noggings, at the mid-height of the wall.

Table 2 - Non-Load Bearing Steel Stud Wall

Height Selection Table

Timber Stud Wall HeightNoggins in timber stud walls must be spaced at 1350

mm maximum centres.

Table 3 - Non-Load Bearing Timber StudWall Height Selection Table

Load Bearing WallsLoad bearing walls in this Installation Guide must be

designed and constructed in accordance with AS 1684

and AS 1720, for timber construction and AS/NZS

4600 and AS 3623 for light-weight Cold-Formed-

Formed (CFS) steel construction.

Load bearing walls must be designed and constructedto take all loads without any cladding or lining.

InstallationInstallation is to be in accordance with the BGC

Plasterboard Fixing Instruction Manual: BGC PB201

DEC 2003 and as set out in this manual.

Fire rated plasterboard must be fastener fixed to steel

and timber framing.

Stud adhesive must not be used.

For double-layered systems all joints must bestaggered and butt joints in the outer layer may be

reinforced with laminating screws.

All perimeter gaps and penetrations must be fully

sealed with fire rated mastic sealant, to attain the

required FRL and RW ratings.
