IntRwall


IntRwall is a light-weight separating wall system for apartment buildings. First introduced on 88 storey Eureka Tower project in Melbourne, plasterboard based IntRwall has proved to be a viable alternative to autoclaved aerated concrete construction.
    Features & Benefits
  • Speedy installation
  • Reduced sizes of building elements and therefore reduced cost of building structure and foundations
  • Ease of installation
  • Components are easily manhandled without the need for heavy lifting equipment
  • All components can be installed by the plasterer – no additional trades required and therefore easier trade
  • No need for wet trades and therefore less mess on site
  • Reduced number of crane lifts (TBC on project basis)
  • Limiting wall height can be increased by reducing stud spacings
  • Lower embodied energy as compared to heavy-weight construction (TBC on system by system basis)

Boral IntRwall™ is the next generation of the highly successful Eurekawall® separating wall system for apartment buildings.

Based on the same panelised construction principles, Boral IntRwall™ represents the latest advancement in lightweight fire rated and acoustic rated technology, offering reduced construction costs without compromising on performance.

The system is ideal for high-density multi-residential construction due to its excellent acoustic performance, narrow footprint and flexibility. The services can be easily run in the wall cavities without the need for fire rating of penetrations through external linings. The plastering contractor installs all components, allowing better coordination of works on site.

Narrow width
• Increased ‘lettable space’

IBS rod has been removed in some systems
• Easier installation details compared to Eurekawall®
• Reduced installed costs
• Easier quality inspection compared to Eurekawall®

Wall cavities are present on one or both sides of the system
• Services can be easily incorporated within the system

The bulk of fire separation is provided by the Shaftliner panels
• Standard installation details are used for internal linings in cavity walls
• Service penetrations in internal linings do not need to be fire rated

Fire and acoustic tests have been carried out by CSIRO
• CSIRO test results and opinions are available to support claimed fire and acoustic ratings
• Proved FRLs up to -/120/90
• Proven acoustic ratings up to Rw = 68 dB (Rw + Ctr = 56dB)

IntRwall™ system has been patented
• The system cannot be easily copied by competitors

IntRwall™ predecessor Eurekawall was developed by Boral in 2002
• Boral developed a high level of expertise in the system
• Boral technical and sales teams can provide a high level of technical support
• A large number of construction details have been developed to suit various design requirements
