Hebel Low-Rise Multi-Residential PowerPanelXL / PowerPanel50 Intertenancy Wall System

CSR Hebel PowerPanelXL / PowerPanel50 Intertenancy Wall System is a lightweight non-loadbearing wall construction system suitable for use in low-rise residential buildings, that provides a fire rating of up to 90/90/90, and an STC rating between 58-65. The system has been independently tested and assessed with a CodeMark certification to meet New Zealand Building Code.

This wall configuration consists of Hebel (non-load bearing) PowerPanelXL / PowerPanel50 panels installed vertically and secured to the structural load-bearing frame. The system utilises an aluminium bracket system which provides the wall with a discontinuous construction for acoustic performance.

CSR Hebel® Intertenancy Wall System comprises:

  • A central single layer of PowerPanel50 or PowerPanelXL Hebel steel-reinforced Autoclaved Aerated Concrete (AAC) panels, and;
  • Single stud timber or /steel framing walls built on both sides of the AAC panels with a minimum gap of 10mm between the framing and the AAC panel, including 90mm cavity insulation on both sides and lined with 10mm minimum thickness plasterboard.

PowerPanelXL is 75mm thick and PowerPanel50 is 50mm thick. The panels have square edges and are manufactured in a range of stock sizes. 

Key Features
  • Panels installed vertically and available in 2.4, 2.7 2.55 and 3 metre lengths which minimises on-site cutting and wastage
  • Fast and easy to install with simple system components
  • CodeMark (CM20222) ensures the systems offer an easy solution for fire and acoustic compliance
  • The systems do not require the installation of fire-rated plasterboard between floor levels at joists and in the roof space
  • For projects where 75mm thick Hebel PowerPanelXL is wanted or needed, there is a benefit from high levels of acoustic performance, and the same high fire rating performance of the PowerPanel50 Intertenancy Wall Systems
  • CodeMark certified for easy inspections
  • Achieves an STC rating of between 58-65
  • Provides FRR of up to 90/90/90
Scope of Use

The system is a proprietary high-performance wall system that provides horizontal fire and acoustic separation between adjacent tenancies in the same building.

The core component of the system is a high-tech Autoclaved Aerated Concrete (ACC) panel and aluminium bracket installed between traditional timber framing, insulated and plasterboard lined on the outer face.  A cavity is created between the ACC panel and the timber framing through the use of a proprietary inter-tenancy aluminium bracket. The Hebel Intertenancy System is suitable for use in medium and high-density housing, e.g. terraced housing.
