Introduction.CSR Gyprock and Fibre Cement (GFC) steel
frame wall systems use zinc coated steel componentswith one or more layers of Gyprock® plasterboardand/or CSR Fibre Cement linings fixed to one orboth sides. A wide choice of systems is available forboth fire rated and non-fire rated applications in non-loadbearing and loadbearing situations.
These wall systems are most often used in internalnon-loadbear ing applications, in commercial,industr ial, institutional, residential and high-r iseresidential construction. Systems are also available forexternal walls
DesignConsiderations.
STRUCTURAL DESIGN.
All walls must be designed for the applied loads.Guidance is given for the selection of Rondo studs andLysaght, Stramit or UniSpan top hat sections for non-loadbearing internal walls only.
Load bear ing walls and walls subject to windpressures shall be appropriately designed to meet therelevant Australian Standards or construction manuals.
Non Loadbearing Walls.
Maximum wall height and the required stud sizemay be selected from Table B1 to B5, appropriate forthe selected system. These walls are designed for lateralloads only, using the composite action of the frame andsheeting.
Non load bearing walls in this manual have beendesigned as follows:
• Minimum design pressure of 0.25kPa and amaximum deflection of (height ÷ 240) or 30mmmaximum. (Based on BCA Specification C1.8, 3.4(b))
• Fire rated walls lined with GYPROCKFYRCHEK with studs selected from Table C2meet the requirements of BCA Specification C1.8Clause 3.4 – Walls generally.
Internal wall studs are friction fitted into trackswith no clearance at the bottom and a minimumallowance for vertical expansion of 15mm at the top.Where vertical building movement is expected anadditional gap is required. In this case deflection headtracks must be used. Refer to Section ‘Z’ for details.
Staggered stud walls using top hats are fixed to thebase track and use Rondo Nº126/152 clip at the toptrack. Staggered stud walls using Rondo C studs mustuse the CSR staggered stud clip to restrain the studfrom twisting.
Wall tracks must be fixed to floors and ceilings at600mm maximum centres. Each plate fixing isrequired to withstand a shear load of 0.75kN for aUDL of 0.25kPa and 1.1kN for UDL of 0.35kPa.
Tall residential buildings often have operable doorsand windows, resulting in internal walls being subjectto wind pressure. In these cases, walls must be designedfor the appropriate loads.

The Red Book™B5.
Loadbearing Walls.
Walls designed as load bearing and lined withGYPROCK FYRCHEK meet the requirements ofBCA Specification C1.8 Clause 3.4 – Walls generally.
The building designer must ensure load bearingwalls have been designed:
• To resist all applied loads.
• To be in accordance with AS4600 or AS3740.
• Assuming no contr ibution to axial strength isrequired of the wall linings.
To meet the stated Fire Resistance Level (FRL), theaxial load capacity of some wall systems is reduced.This is a result of the steel weakening at hightemperature during a fire test. The systems are notedwith an Axial Capacity Reduction percentage(ACR%). For these systems, the designer must increasethe applied loads before selecting stud size tocompensate for the axial capacity reduction percentage,as shown in the system specification.
Studs are to be placed at 600mm maximum centreswith nogging provided as detailed in Table B1 or B2,or as noted in the system table.
The capacity of head and base tracks for wallssubject to wind loads must be checked. Typically, studsare cleated at head and base with a Rondo anglebracket. Contact Rondo for more information ondesigning walls subject to wind loads.
FIRE RESISTANCE.
The steel frame wall systems in this manual aresuitable for the stated FRL when designed inaccordance with the structural considerations above.
CSR GFC fire rated steel stud wall systems havebeen designed with fire protection that limits thetemperature of the steel framing to a maximum of450°C at the fire resistance level (FRL) stated.Therefore the structural design of the framing needonly provide for normal temperature conditions, andno additional consideration of fire rating is required. Insome systems this temperature is exceeded and theaxial capacity of the stud must be reduced tocompensate for the loss of strength. The percentagereduction is noted for each affected systems. For moreinformation regarding the fire resistance of steel studwalls, refer to BRANZ assessment FAR 2357.
To protect structural steel beams and columns thatare entirely within a wall, the FRL of the wall systemmust be at least equivalent to that required by thestructural member. For example, a wall system withFRL 90/90/90 provides FRL 90/–/– for a steelcolumn within the wall.
Framing & Lining.
Steel framed walls required to have an FRL mustcomply with the following:
• Framing must be made from steel of BMT 0.5mmto 2.0mm.
• Wall plates must be fixed to the fire rated supportstructure with steel fasteners such as expansionanchors, easy drive masonry anchors and powerdriven fasteners.
• Plasterboard must be screw or nail fixed only,adhesive is not permitted.
• In wet areas, Gyprock Fyrchek MR™ must be usedin lieu of Gyprock Fyrchek™.
• For single layer applications, butt joints must bebacked by either a stud or nogging. This is notrequired for recessed joints.
• For double layer vertically sheeted applications, buttjoints may be reinforced using laminating screwswithout the need for framing support.
• Joints in the outer layer of all systems lined withplasterboard or Wallboard must be set withGyprock® paper tape. As a minimum, a single coatfinish may be used.
• Joints in external systems lined with CSR FibreCement Texture Base Sheet must be set with thetape and compound recommended for the texturecoating system
• Spacing of girts in horizontally framed systems mustbe as shown in installation detail FIG B17.
For general installation information, refer to FIGB2 to B18.
For information on frame design and detailing,including treatment at junctions, sub floor and roofareas, cavity barriers and penetrations, refer to Section‘Z’ of this manual, and brochure NºGYP544, GyprockSteel Frame Wall Systems.
The Fire Resistance Level (FRL) of the systemsdetailed in this section will not be detr imentallyaffected by;
• Increasing the thickness of the wall.
• Increasing the cross-sectional dimensions of theframing elements.
• Decreasing the stud spacing.
• Decreasing the fixing centres of wall sheet materials.
• The inclusion of bulk cavity insulation materialssuch as Glasswool, Rockwool and Polyester.
• The use of Fyrchek™ MR plasterboard in lieu ofFyrchek™ plasterboard of the same thickness.
• Additional layers of plasterboard or CSR FibreCement.
B6. The Red Book™
• Wall curved in plan with a radius of curvature noless than 3m.
• The addition of a timber cladding.
• The addition of any other cladding meeting BCASpec C1.1 Clause 2.4.
Caulking.
To attain the specified FRL, all perimeter gaps andpenetrations must be carefully and completely filledwith appropriate caulking material. CSR Gyprock FireMastic or other tested fire and acoustic rated materialof equivalent or better performance must be used.
Details for fire sealing of penetrations is given inSection ‘Z’.
Vermiculite plaster has no capacity to accommodatebuilding movement and may not be suitable for use as ageneral purpose fire rated caulking. Its use is specified insome wall/ceiling junctions, refer to brochureNºGYP570, Gyprock® Ceiling Systems Installation Guide.
ACOUSTIC PERFORMANCE.
The acoustic performance of wall systems isexpressed in terms of Rw and Rw+Ctr whereappropriate. The performance of the as-built systemmay be affected by – sound flanking, the effectivenessof workmanship and caulking, the presence andtreatment of penetrations, and the inclusion ofstructural elements and bridging items. Refer toSection ‘A’ for detailed information on addressingthese issues.
General Notes.
• The acoustic performance of systems may beadversely affected by the use of studs with higherBMT or closer spacings than those specified, oradditional linings fixed with battens.
• The acoustic performance of CSR wall systems isnot adversely affected by the order of lining sheetsthat are fixed direct to framing. In non fire ratedsystems, to attain the stated acoustic performance,use CSR Gyprock Wet Area Acrylic Sealant, CSRGyprock Fire Mastic or other tested acoustic ratedmaterial of equivalent or better performance.

CSR GFC recommends steel componentsmanufactured by Rondo Building Services Pty Ltd.Additional information on the steel components canbe obtained from the Rondo Building Services PtyLtd, telephone 1300 367 663. For information onLysaght, Stramit or UniSpan top hat sections, pleaserefer to the appropriate component manufacturer, andthe Gyprock® Steel Frame Wall Systems InstallationGuide, NºGYP544. Other steel components ofequivalent performance may be used, however it is theresponsibility of the manufacturer of the component tosubstantiate equivalent performance with therecommended component.
For detailed information on wall junctions,intersections, frame attachments and penetrations, referto Section ‘Z’ of this manual.
Walls curved in plan may be built with steel studframes. Selection information on stud centres andplasterboard thickness for various curvatures can befound in brochure NºGYP544, Gyprock® Steel FrameWall Systems.
WALLBOARD & PLASTERBOARD FIXING.
Walls may be built to achieve a particular ‘Level ofFinish’ as defined in AS/NZS2589.1. The Level ofFinish specified can have requirements for framealignment, jointing and back blocking methods, andsheet orientation. CSR Fibre Cement Wallboard andGyprock® plasterboard may be installed vertically orhorizontally, although for some Levels of Finishhorizontal sheeting must be used.
Walls lined with Gyprock® plasterboard or CSRFibre Cement Wallboard may be finished with tiles.For tiles greater than 32kg/m2 or over 6.5mmthickness, specific installation details apply. Refer tothe appropriate installation manual.
PLASTERBOARD JOINTING & FINISHING.
Refer to the Gyprock® Residential InstallationGuide, NºGYP547 and CSR Fibre Cement Wet AreaLining Systems, NºFC101 for detailed jointing andfinishing information.
It should be noted that:
• Multi-layered systems only require jointing andfinishing of the outer layer.
The Red Book™B7.
• It is a requirement of the BCA that a water resistanttaping compound, such as CSR Gyprock FibreCement Wet Area Base Coat be used at verticalwall junctions and horizontal and vertical jointswithin wet areas such as showers.
CONTROL JOINTS.
Control joints must be installed to allow forstructural movement. Allowance for movement mustbe made through the frame, lining and any tiles. Referto Section ‘Z’ of this manual for details.
Control joints must be installed at all constructionjoints in the building and at the following locations:
• Non-tiled internal walls with fibre cement outerlayer – at 7.2m maximum centres.
• Tiled internal walls with fibre cement outer layer –at 4.2m maximum centres.
• Walls with plasterboard outer layer – at 12mmaximum centres.
• External walls – refer to the appropriate installationmanual.
EXTERNAL WALLS.
Gyprock® GFC external wall systems rely on arange of cladding systems to provide weatherresistance. There is a range of effectiveness of thesesystems, and CSR Gyprock recommends the claddingbe installed with a drained cavity. Cavity systems allowdrainage and drying of any water that penetrates, andare known to have good long-term performance.
Sarking is also recommended to provide additionalweather protection to framing and lining.
External walls require specific design forcondensation control and energy efficiency, dependingon the climate and internal environment. ContactCSR Bradford for information on thermal insulationsystems and products.
