Partiwall® Separating Wall System

Partiwall® Brochure Available Now!

Partiwall® is ideal for separating walls between attached dwellings.

The pioneering system of its kind in Australia, Knauf 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™ Mouldstop 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.

The Partiwall® separating wall system is suitable for attached dwellings Class 1a. For multi-residential buildings, Class 2, 3 and 9C, Knauf recommends the Multiframe™ timber framed construction system (subject to NCC limitations) or IntRwall® separating wall system.

Our Partiwall® Estimator Tool allows you to obtain and submit quotes for Partiwall® Systems.
