TRANSCRIPT
Ceilings Under a Floor and Under a RoofThis section contains a wide range of ceiling solutions that can meet aesthetic, sound insulation and fire protection requirements. These ceiling solutions are for applications under a floor and under a roof. They are either directly fixed to joists or are installed to a concealed suspended steel frame.
Most fire rated ceilings as per National Construction Code (NCC) requirements are rated from below only. [For ceilings fire rated from above, or fire rated from above and below refer to Sections 3.5.1 and 3.5.2] Exterior ceiling applications have additional requirements [Refer to Section 2.2 External ceilings]. This section includes systems, installation instructions and construction details for general and fire rated ceilings.

CEILINGS UNDER A FLOOR AND UNDER A ROOFGeneral Requirements Installation
Non-Fire Rated
Fire Rated
Install control joints in plasterboard ceilings at: 12m maximum intervals All control joints in the structure Any change in the substrate material At the junction of a large room and passageway.
All ceilings in this section are non-trafficable. Do not walk on plasterboard ceilings!
Limit dead loads on plasterboard ceilings to 2 kg/m² for plasterboard spanning 600mm framing centres.
Limit dead loads on plasterboard ceilings to 2.5 kg/m² for plasterboard spanning 450mm framing centres where the plasterboard can usually span 600mm centres.
Attach ceiling fixtures to framing members only. Ensure the framing is designed to carry any additional load.
Only joint the face layer. As a minimum to achieve the FRL, only use paper tape and: Two coats of MastaBase/MastaLongset, or Three coats of MastaLite
Use approved fire rated penetration details. Fire penetrations may require fire collars or other devices to maintain fire performance.
Use fire sealant on all gaps and around perimeter, vermiculite plaster is not permitted.
All structures supporting fire rated ceilings must have an equal or greater FRL than the ceiling they support eg, a ceiling with FRL of 90/90/90 must be supported by a load bearing wall or column with FRL of at least 90 minutes.
Structural beams enclosed by a fire rated ceiling are given the same structural protection rating as the ceiling eg, a structural beam located above a ceiling rated to FRL 90/90/90 would have FRL of 90/–/–.
Compensate for uneven framing by attaching a furring channel system with adjustable direct fix clips.
Timber trusses may settle or move with changing seasons. Reduce occurrence of plasterboard cracking due to this movement by fixing plasterboard to furring channel or battens.
For acceptable modifications or variations to fire rated systems. [Refer to Section 2.3 Fire Resistance]
The FRL and RISF will not be reduced if a fire rated ceiling is built on an angle eg, a raked ceiling.
Consider the corrosive effect of sea spray on steel components, select framing and fasteners accordingly.
The FRL will not be reduced if the insulation directly above plasterboard is omitted.

Cut Top Cross Rail (TCR) and furring channel to leave 10mm expansion gaps at each wall.
Stagger joints in TCR and furring channel by 1200mm.
Install additional framing members around openings.
Timber battens are not permitted in fire rated ceilings.
Steel framed ceiling systems must be designed by an engineer according to the relevant Australian Standard.
Framing members in this section are designed using either steel or timber joists, Lipped C type steel studs or a furring channel system.

1. Tables based upon downward (suction) and upward (uplift) pressures, intended for internal use only.2. Tables include self weight but is not applicable to additional point loads and live loads.3. Tables have not been checked for earthquake actions.4. Tables refer to Knauf Furring Channel of Base Metal Thickness (BMT) 0.42mm of grade G550 steel with ZincalumeTM AM150 corrosion protection. Maximum production
lengths available are 6.0m5. Calculations based upon a single span, double span, or 3-or-more spans and designed in accordance with AS/NZS 4600:2005 Cold Formed Steel Structures.6. Connections to clips must be checked with the Clip Capacity Table. Refer to Construction Details for perimeter detail.7. Serviceability Load Case 1: G+U, with deflection limited to Span/360. Serviceability Load Case 2: G+U+Ws, with deflection limited to Span/200.8. Perimeter anchors at 600mm max centres and 100mm max from ends with minimum 0.7 kN shear capacity.9. The project engineer must approve the nominated pressures and deflection limits are appropriate for a specific project.

CEILINGS UNDER A FLOOR AND UNDER A ROOFPlasterboard Layout and Fixing Installation
Non-Fire Rated
Fire Rated
Sheet ceilings perpendicular to framing members.
First layer butt joints must be over a framing member.
Float face layer butt joints between framing members for: Three layer systems Two layer systems on 600mm centres.
Stagger face layer butt joints by 600mm minimum on adjoining sheets and between layers.
Stagger recessed edges by 300mm minimum between layers.
Follow the back-blocking requirements and butt joint placement for the level of finish selected. [Refer To Section 4]
Sheet ceilings parallel to the light source to reduce the effect of glancing light.
Minimise butt joints by using the longest sheet possible.
Butt joints on underlying layers (not face layer) may be made on the same framing member.
For 2 layer systems at 450mm centres, face layer butt joints may be fixed to framing members.
Plasterboard FixingNon-Fire
RatedFire
Rated
Drive fasteners to just below the sheet surface, taking care not to break the paper linerboard.
Do not fix plasterboard to steel more than 2mm BMT.
Use laminating screws to fix floating butt joints in the second and third layer.
Fastener and Adhesive Method
Apply MastaGrip Stud Adhesive after the frame is clean, dry, and free from grease, dust and other contaminants.
Apply MastaGrip daubs 200mm minimum from fasteners and plasterboard edges.
Fastener Only Method
Use the ‘Fastener Only Method’ in tiled or fire rated areas. Stud adhesive is not permitted.
The ‘Fastener and Adhesive Method’ is recommended for non-fire rated applications.
MastaGrip will:
Minimise fastener popping
Reduce the number of fastener heads that may show in glancing light
Assist in compensating for frame irregularities.
All joints not made on a framing member should be back-blocked in single layer ceiling systems. External ceilings have special requirements. [Refer to Section 2.2]
