Partiwall® Separating Wall System


Partiwall® is ideal for separating walls between attached dwellings.

The pioneering system of its kind in New Zealand, USG Boral Partiwall® has become one of the most widely used separating wall systems in attached villa units and townhouse developments.

Partiwall® is a twin stud wall system, which incorporates a single or double-layer 25mm Shaftliner™ plasterboard fire barrier within the wall cavity.

Shaftliner panels are held in position by lightweight steel H- or I-section studs. Installation of Shaftliner fire barrier is carried out during the framing stage and does not require plasterboard screw fixing, jointing or finishing. The internal wall linings are installed at the plastering stage using conventional installation methods.

Partiwall® permits easy incorporation of services and does not require penetration and perimeter treatment associated with traditional fire-rated systems.

  • Cost-effective and fast to construct
  • No wet trades required
  • No additional trades required at the framing stage
  • Conventional installation of internal linings at the plastering stage
  • Branz Appraised
