IntRwall® Separating Wall System

The next generation of multi-residential separating wall systems

Knauf IntRwall® is the next generation of separating inter-tenancy and corridor wall systems designed specifically for residential apartments.

Knauf IntRwall® is a lightweight separating wall system that offers a number of advantages compared to traditional fire-rated plasterboard systems and alternative solutions. It offers reduced construction costs compared to other options available in the market without compromising on performance. Based on panelised construction principles, IntRwall® is easy and quick to install and does not require heavy lifting equipment.

IntRwall® systems utilise 25mm Shaftliner plasterboard panels and fit between steel I-studs. Outer linings each side of the wall are fixed directly to I-studs, or on furring channels or free-standing steel studs. Services are easily incorporated in wall cavities on one or both sides of the wall.

Knauf advises the use of Rondo steel framing and components to ensure compliance with performance requirements. Designed to be a perfect fit with the shaftliner panel which acts as a fire barrier between the finishing linings, the Rondo 341 J Track has an extended leg to allow for fast and easy installation.

Compliance made easy with Knauf wall and ceiling systems and Insulation

The addition of Knauf Insulation glasswool products to the IntRwall® systems gives you access to fully compliant and complete Knauf branded solutions. IntRwall® satisifes NCC acoustic requirements for inter-tenancy walls, corridor walls and acoustic separation when installed with Knauf Insulation.
