E2. The Red Book™

Introduction.CSR Gyprock and Fibre Cement (GFC) has

developed a wide range of floor/ceiling androof/ceiling systems to meet specific fire and acousticrequirements. The systems include ratings for soundtransmission, sound impact and sound absorption, andfor fire resistance up to FRL 120/120/120.

Generally, the fire resistance of floor androof/ceiling systems is assessed from below, inaccordance with the standard fire test of AS1530.4.This is the requirement of the BCA where lightweightconstruction is used for compartmentation andseparation. Some elements such as fire-isolatedpassageways are required to have an FRL when testedfrom outside. A number of ceiling systems are availablethat offer fire resistance from above to meet thisrequirement.

CSR GFC ceiling systems use var ious fixingtechniques for the attachment of linings. Theseinclude:

a) Direct fixing to timber and steel joists or trussbottom chords.

b) Screw fixing to steel furring channels that areattached to joists.

c) Screw fixing to resilient or resiliently mountedfurring channels.

d) Screw fixing to suspended concealed metal grid.

e) Lay-in panels in suspended exposed metal grid.

DesignConsiderations.

STRUCTURAL.

All floor, roof and ceiling framing must be designedfor the applied loads. Guidance for the selection ofRondo suspension and grid components is given inbrochure NºGYP570 ‘Gyprock® Ceiling SystemsInstallation Guide’. For other elements, refer to theappropriate design standards or handbooks, or contactthe manufacturer for design information.

CSR GFC recommends a minimum designpressure of 0.25kPa (downward) for the ceilingframing. Other wind pressures may be applicable; thedesigner should refer to AS/NZS1170.

Wind loads on external ceilings can be similar tothose on adjacent walls. Pressures can be positive ornegative and the lining, grid and structure should bedesigned to resist the loads. Internal suspension

components, even with down struts, may not besuitable.

The maximum spacing of ceiling framing is600mm. Closer spacing may be required for somelining materials or for design loads greater than 0.5kPa.

CSR GFC Ceiling systems have been designed fortimber or steel framing as noted in the systemspecification. Timber framing shall be solid timber orengineered floor joist such as LVL Glulam, plywebjoists, or trusses made from solid timber framing mustbe designed in accordance with AS1720.1. or AS1684

Steel framing for direct fixing of linings shall havebase metal thickness (BMT) 0.5 - 1.6mm. Framingmay be trusses, top hats, C sections, furring channels,or similar members. in all cases they should bedesigned in accordance with AS4600.

For steel components in external environments, inheavy industr ial areas or coastal areas, additionalcoatings may be required. Refer to AS/NZS2785 forguidance

Direct-Fix Framing Systems.

Ceiling linings may be fixed directly to primarytimber or steel framing, or to secondary members suchas furring channels and battens.

Timber members to which plasterboard will befixed must comply with AS1684 ‘Residential Timber-Framed Construction’, or be designed in accordancewith AS1720.1 ‘Timber Structures: Design Methods’.

Steel framing to which plasterboard will be fixedmust comply with AS/NZS4600, ‘Cold Formed SteelStructures’.

Suspended Ceiling Systems.

Ceiling suspension systems must be designed toAS/NZS2785 ‘Suspended Ceilings – Design andInstallation’. Ceilings in this manual are not trafficable.Trafficable systems shall be designed in accordancewith AS1657 ‘Fixed Platforms, Walkways, Stairwaysand Ladders’.

Ceilings Rated from Above.

Ceiling systems with plasterboard linings on top ofjoists are not trafficable or intended to be used forstorage. The joists should be designed for all imposedloads including construction loads where fixing ofsheets is required from above. Appropriate barriers andsignage should be installed to prevent access.

FIRE PERFORMANCE.

Gyprock® fire rated ceiling systems. have beendesigned with fire protection that protects the framing.

The Red Book™E3.

This means that no consideration of steel or timberframing design need be given for the fire rating.

To protect structural beams that are entirely withinthe ceiling space, the structural adequacy componentof the ceiling system FRL must be at least equivalentto that required by the structural member. Forexample, a ceiling system with FRL 90/90/90 providesFRL 90/-/- for a steel beam within the ceiling.Systems are available for beams that are not entirelyenclosed.

Framing and Lining.

Plasterboard must be screw fixed only, adhesive isnot permitted. Joints in the outer layer of all systemsmust be set with Gyprock® paper tape. As a minimum,a single coat finish may be used.

For general installation information refer to FIG.E3 to F9. Detailed fixing information is provided inbrochures: Gyprock® Ceiling Systems InstallationGuide NºGYP570, CSR Gyprock Shaft SystemsNºGYP546, CSR Fibre Cement Ceiling SystemsNºFC129, CSR Fibre Cement ExpressWall FacadeSystem NºFC126 and CSR Hebel SoundFloor DesignGuide, NºHBL751-SFS.

Ceiling systems are generally shown in a horizontalorientation. The system FRL will not be reduced ifceilings are built on a rake. The support framing,including lateral bracing, must be designed consideringthe slope of the ceiling.

Alternative support framing members may be usedwhere timber joists are shown without reducing thesystem FRL. These members include, but are notlimited to, steel, composite steel/timber joists,laminated timber joists, and trussed or plywood webjoists.

System specifications for minimum cavity depthsand floor surface finishes relate to acousticperformance only.

Caulking.

To attain the specified FRL, all perimeter gaps andpenetrations must be carefully and completely filledwith appropriate caulking mater ial. In fire ratedsystems, to attain the stated FRL use CSR GyprockFire Mastic or other tested fire rated material ofequivalent or better performance. Details for firesealing of penetrations is given in Section ‘Z’.

Vermiculite plaster is not to be used as a generalpurpose fire rated caulking. Its use is specified in somewall/ceiling junctions; refer to Gyprock® CeilingSystems Installation Guide NºGYP570. Vermiculiteplaster has no capacity to accommodate buildingmovement.

ACOUSTIC PERFORMANCE.

Sound Transmission.

Sound flanking, the effectiveness of workmanshipand caulking, the presence and treatment ofpenetrations, and the inclusion of structural elementsand br idging items, may affect the acousticperformance of ceiling systems. Refer to Section ‘A’for detailed information.

Alternative structural framing systems includingsteel, and composite steel/timber joists, laminatedtimber joists, and trussed or plywood web joists may beused without reducing the system rating. The stated orimplied minimum cavity depth must also bemaintained.

For effective control of sound in the flanking pathof a floor or roof space, acoustically rated walls shouldcontinue to the underside of the floor or roof above.Alternatively, select a detail from section ‘Z’ equivalentto the required Rw or Rw + Ctr performance of thewall.

In non-fire rated systems, to attain the stated soundtransmission performance use CSR Gyprock® WetArea Acrylic Sealant, Gyprock® Fire Mastic or othertested acoustic rated material of equivalent or betterperformance.

Sound impact performance is stated as Ln,w + CI.Note that a lower value of Ln,w + CI has a higherimpact performance.

Floors finished with carpet and underlay achievebetter impact performance than those with hardsurfaces such as floorboards and tiles. If carpet issubsequently removed (from a system that uses it in itsperformance value), the floor may no longer meet theBCA impact requirements.

Sound Absorption.

Gyprock® Perforated Plasterboard, Ecophon andCelotex ceiling products, have sound absorptionqualities. These products may be used to influence thereverberation time of a room in order to improve thesound quality.

Product performance is expressed as NRC inaccordance with ASTM C423.This is calculated as theaverage of four frequencies in the range 250 – 2000Hz.Sound absorption values vary from 0 (total reflection)and 1.00 (total absorption) NRC values can be foundin system CSR 890

InstallationFor detailed information on junctions with walls,

access hatches, light fixtures, control joints andpenetrations, refer to Section ‘Z’ of this manual.

Plasterboard & Fibre Cement Fixing.

Ceilings may be built to achieve a particular ‘Levelof Finish’ as defined in AS/NZS2589.1. The Level ofFinish specified can have requirements for framealignment, jointing and back blocking methods.

Lining sheets must be installed with the long edgeat right angles to the direction of the framing to whichthey are fixed. Refer to FIG. E3 to E9 for generalfixing information using fastener and fastener/adhesivefixing methods. Detailed fixing information isprovided in Gyprock® Residential Installation Guide,NºGYP547, CSR Fibre Cement Ceiling SystemsNºFC129 and Gyprock® Ceiling Systems InstallationGuide, NºGYP570.

Jointing.

Refer to the Gyprock® Residential InstallationGuide, NºGYP547 for detailed jointing and finishingof ceilings lined with plasterboard. In multi-layersystems, jointing and finishing is required on the visibleouter layer only.

Expressed joints are recommended for ceilings linedwith CSR Fibre Cement products. Refer to CSRFibre Cement Ceiling Systems NºFC129 for moreinformation.

Control Joints.

Control joints are used to reduce the possibility ofcracks forming from structural movement, thermal andmoisture movement and the like. Locations for jointsshould be chosen by the designer with regard tobuilding shape, structural breaks, changes of substrate,and joint appearance.

Ceiling systems with plasterboard linings must havecontrol joints at 12m maximum spacing in bothdirections. Ceilings lined with CSR Fibre CementWallboard should have joints at 3.6m in most cases. Foradditional information, refer to CSR Fibre CementCeiling Systems NºFC129.
