Standard SRP™ Stud Non Fire rated, Non Acoustic, Fire rated or Acoustic, SRP™ Whisperwall™ - STC52 Rating Both Side Single LIned, SRP™ Whisperwall™ - STC58 One Side Single, Other Side Double Lined

»» Use full height sheets only, where possible.

»» Vertical sheet joints are touch fitted and must occur over SRP™ Studs.

»» Stagger vertical sheet joints within layers by minimum of 300mm against the inner layer and on opposite sides of the frame by 600mm [see FIGURE 32].

»» If horizontal sheet end joints are unavoidable they must be over SRP™ Nogs. Stagger sheet joints within layers and on opposite sides of the frame.

»» For fastening use the appropriate size GIB® Grabber® Drywall Self Tapping Screws at 300mm centres vertically or as specified in the appropriate GIB® specifications referenced above. Sheet end and edge distances: minimum 75mm, maximum 100mm from sheet top and bottom ends and 12mm from sheet vertical edges [see FIGURE 28 and FIGURE 29].

»» For Standard SRP™ Stud partitions install the plasterboard lifted by 10mm from the floor level. A 10mm packer to temporarily hold the plasterboard in position is an option to aid installation [see Figure 28].

»» For Some Fire Rated and Acoustic walls fastening the plasterboard to the top or bottom SRP™ Track is not allowed. For more information see GIB® Fire Rated Systems October 2012, GIB® Noise Control Systems March 2006 and also refer to deflection and/or seismic separation note below.

»» For some Fire Rated Standard SRP™ Stud partitions, fastening the linings to top and bottom SRP™ Tracks is permitted as long as the lining fasteners do not connect the SRP™ Studs and SRP™ Tracks. Refer to GIB® Fire Rated Systems October 2012 for particular application.

»» For Non Fire Rated/Non Acoustic Standard SRP™ Stud partitions for single level building applications, fastening the linings to top and bottom SRP™ Tracks at 300mm centres is an option as long as the fasteners do not connect any of the SRP™ Studs to the top and bottom SRP™ Tracks.

»» For deflection and/or seismic separation to allow for unrestrained movement of the wall structure, do not screw the board to the top or bottom SRP™ Track. The minimum top bottom end distance of 75mm will need to be adjusted, if required, especially for longer leg length SRP™ Tracks.

»» As per the relevant GIB® documentations, the main points for GIB® plasterboard installation are:

  • During fastening, hold plasterboard firmly against framing.
  • To allow for stopping, slightly sink the fastener, without breaking the gypsum face paper.
  • For easy installation use an electric drywall screwgun with an adjustable depth control head and an appropriate bit for the screw head.
  • In case of any accidentally overdriven screw, where the GIB® plasterboard core and/or face paper is damaged, insert a new screw approximately 50mm from the overdriven screw and then remove the overdriven screw.
  • Do not screw within 200mm of any glue daubs as this can lead to screw popping.
  • For more information refer to the relevant GIB® Plasterboard installation documentation.

»» For double layer standard partitions, leave the inner layer unstopped and for the outer layers all fastener heads stopped and all sheet joints tape reinforced and stopped in accordance with GIB® Site Guide.


To achieve the required STC rating wall, use full height sheets only as specified in SRP™ STC and FRR specification.
