Partiwall Intertenancy System
Description

USG Boral Partiwall is an intertenancy solution for separating walls between attached dwellings.

Partiwall is a twin stud wall system, which incorporates a single or double layer of 25mm Shaftliner plasterboard fire barrier panels 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 stand 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.

Partiwall was developed to suit the normal pattern of construction and follow-up trades.

Maintenance

The Partiwall System does not require maintenance but USG Boral recommends that a visual check of the wall is undertaken when the opportunity arises.

In the event that moisture gets into the cavity then the lining must be removed and the Partiwall inspected, as moisture may cause degradation to the structural integrity of the Shaftliner or Firestop.
