Party walls with sound absorption and fire resistance

A party wall separates one building from another, so acoustic performance is essential for the wellbeing of occupants in both buildings. This is particularly important in terraced buildings, which are vulnerable to noise pollution from both sides. Building materials must also help to resist the spread of fire through the wall and provide the necessary thermal performance.

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 construction. Excellent acoustic performance, ease of construction and design flexibility make PartiWall the system of choice for projects ranging from side-by-side duplexes to multi-unit developments.

Benefits of our party wall solutions

Insulation for Party Walls

In a separating party wall, insulation is required, and should be fully-filled, for thermal performance to prevent heat loss through thermal bypass, and also for acoustic performance to reduce the noise transfer between dwellings.

In this application, the glasswool insulation is installed as the walls are built, with batts being friction fitted between the inner and outer leaves of the wall and in between wall ties.

Gypsum for Party Walls

Gypsum-based products are widely used in party walls due to their excellent fire resistance, acoustic insulation, and lightweight construction capabilities. They are crucial for meeting National Construction Code (NCC) requirements in residential and commercial developments.

Panelised systems are designed for fast Installation and provide a much lighter alternative to traditional masonry separating walls,

Thermal and acoustic performance

Party walls do more than divide spaces — they define how comfortable and quiet a building feels to live or work in. Achieving the right thermal and acoustic performance requires a system-based approach, combining high-performance plasterboard with purpose-designed insulation to meet the demands of modern construction. Acoustic insulation minimises sound transmission between tenancies, while thermally efficient insulation reduces heat transfer and supports energy ratings. Paired with plasterboard specified for noise reduction and thermal resistance, these systems deliver compliant, comfortable environments. Whether you’re building apartments, townhouses or commercial spaces, the right combination of plasterboard and insulation in party wall assemblies ensures performance that lasts.

Non-combustible products

Fire safety in party walls starts with the right materials. Non-combustible plasterboard and insulation work together to contain the spread of fire between occupancies, protecting lives and structural integrity. Where building codes require non-combustible construction — particularly in multi-residential and commercial buildings — specifying tested, compliant plasterboard and insulation is essential. Non-combustible insulation maintains its integrity under extreme heat, while fire-rated plasterboard provides a robust barrier that slows fire progression and limits smoke movement. Together, they form a party wall system that meets the most stringent fire safety requirements without compromising on acoustic or thermal performance.
