INTERNAL STEEL STUD WALLSGeneral Requirements
3.1.1Installation
General Requirements
Non-Fire Rated Fire Rated
Install control joints in plasterboard walls: At 12m maximum intervals With tiles at 4.8m maximum intervals (plasterboard or Villaboard) With fibre cement at 9m maximum intervals for steel framing <0.8mm BMT With fibre cement at 6m maximum intervals for steel framing >0.8mm BMT At all control joints in the structure At any change in the substrate material At the floor line in stairwells. Cover the gap with a moulding fastened to one edge.
Only joint the face layer. Use paper tape with either two coats of MastaBase/MastaLongset or three coats of MastaLite. Alternatively use Knauf Bindex Fire and Acoustic Sealant according to the Tech Data Sheet.
Use approved fire rated penetration details. Fire penetrations may require fire collars or other devices to maintain fire performance.
Pack any gaps between the top of the wall and the underside of the roof covering with mineral fibre or other suitable fire resisting material.
Use fire sealant on all gaps and around perimeter, vermiculite plaster is not permitted.
Attach all fixtures to studs or noggings. Wall anchors must not be directly fixed to only the plasterboard of fire rated walls.
For acceptable modifications or variations to fire rated systems. [Refer to Section 2.3 Fire Resistance]

3.1.1 INTERNAL STEEL STUD WALLSFramingInstallation
Non-Fire Rated
Fire Rated
Fix the bottom track and top track or deflection head at 600mm maximum centres and 100mm maximum from each end.
Use a deflection head track if soffit movement of up to 20mm is expected. For higher requirements contact Knauf.
Space studs at 600mm maximum centres. Follow the table of nogging requirements and the stud clearances in the Construction Details.
Face studs in the same direction if possible, to allow easier fastening of plasterboard. However, installation of some services may require the studs to be positioned in opposite directions. [Refer to Figures 121, 122 and 123]
Push studs down completely into bottom track.
Noggings are permitted to assist the fixing of services. Copper Chromium Arsenate (CCA) treated timber must not be used.
Plumbing and electrical services must not protrude beyond the face of the stud.

Wall heights have not been checked for earthquake actions or any imposed ceiling loads during an earthquake.4. Tables refer to Knauf Steel Studs of grade G300 steel with ZincalumeTM AM150 corrosion protection. Maximum

next to wall height, if a different BMT compared to the stud is required.7. Connections to base track and head track checked. Head track checked with a maximum 20mm overlap length of the
stud to DH-Track (max 20mm downward and 10mm upwards overhead soffit deflection).8. Serviceability wind pressure taken as 67% of ultimate, and serviceability deflection limited to either height/240 or

1. Maximum wall heights based upon lateral pressures and the deflection limits stated. Table not suitable for external walls.2. No noggings are required in acoustic stud walls.3. Wall heights include self weight but are not applicable to axially loaded (load bearing) studs. Point loads and other loads such
as shelf loads or live loads are not considered, and must be checked with Knauf.4. Wall heights have not been checked for earthquake actions or any imposed ceiling loads during an earthquake.5. Tables refer to Knauf Acoustic Steel Studs of grade G300 steel with ZincalumeTM AM150 corrosion protection. Maximum
production lengths available are 6.0m6. Calculations based upon a single span and designed in accordance with AS/NZS 4600:2005 Cold Formed Steel Structures.7. Base track must be 0.5mm Base Metal Thickness (BMT) or greater. Deflection Head Track BMT is stated in the table.8. Connections to base track and head track checked. Head track checked with a maximum 20mm overlap length of the stud to
DH-Track (max 20mm downward and 10mm upwards overhead soffit deflection).9. The project engineer must approve the nominated lateral pressures and deflection limits are appropriate for a specific project.

3.1.1 INTERNAL STEEL STUD WALLSPlasterboard LayoutInstallation
Maximum Wall Height Tables apply to Knauf steel components. Alternative components may
be used if their performance is equivalent or better and they comply with the relevant standard. All components must be installed in accordance with the manufacturer’s literature.
Plasterboard Layout
Non-Fire Rated
Fire Rated
Alternate from one side of the wall to the other when fixing the plasterboard sheets.
Vertical joints must be 200mm minimum from the edge of any opening such as windows and doorways to minimise cracking at the joints.
Install sheets horizontally when using Knauf Acoustic Stud. Float and back block butt joints according to Installation figures.
Horizontal Layout
Stagger butt joints in single layer systems by 300mm minimum on adjoining sheets and on opposite sides of the wall.
Stagger butt joints in multi layer systems by 300mm minimum on adjoining sheets and between layers.First layer butt joints must be backed by a stud or back-blocked. [Refer to installation diagrams]
Stagger recessed edges by 300mm minimum between layers.
Stagger recessed edges in single layer systems by 300mm minimum on opposite sides of the wall or alternatively, back by a nogging.
Vertical Layout
Stagger butt joints in single layer systems by 300mm minimum on adjoining sheets and on opposite sides of the wall.
Stagger butt joints by 300mm minimum on adjoining sheets and between layers.
First layer butt joints must be backed by a nogging or back-blocked.
First layer butt joints must be backed by a nogging.
Stagger recessed edges by 300mm minimum between layers and on opposite sides of the wall.
Install plasterboard sheets horizontally when practical to minimise stud twisting and reduce the effect of glancing light.
Minimise butt joints by using long sheets.

INTERNAL STEEL STUD WALLSPlasterboard Fixing
3.1.1Installation
Plasterboard Fixing
Non-Fire Rated
Fire Rated
Drive screws to just below the sheet surface, taking care not to break the paper linerboard.
Laminating screws can be used to fix butt joints in the second and third layer.
Screw 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 screws and plasterboard edges.
Screw Only Method
Use the ‘Screw Only Method’ in tiled or fire rated areas. Stud adhesive is not permitted.
The ‘Screw and Adhesive Method’ is recommended for non-fire rated applications.
MastaGrip will:
Minimise screw popping
Reduce the number of screw heads that may show in glancing light
Assist in compensating for frame irregularities.
