Design and Installation Guide
This Design Guide has been
prepared as a source of information to provide general guidance to
consultants – and in no way replaces the services of the professional consultant and relevant engineers designing the project.
It is the responsibility of the architectural designer and engineering parties to ensure that the details in this Design and Installation Guide are appropriate for the intended application. The recommendations of this guide are formulated along the lines of good building practice, but are not intended to be an exhaustive statement of all relevant data.

Better buildings are constructed with Hebel
Hebel is a lightweight steel-reinforced Autoclave Aerated
Concrete (AAC) that has been used in Europe for over 70 years and here in Australia for over 20 years.Hebel. A high-performance lightweight concrete panel systemHebel is the innovative and sustainable, high-performance and lightweight concrete panel system of the future – available today. Easy to install, strong and solid Hebel steel reinforced panels are highly versatile and can be used on all sites to provide extremely solid, safe and highly secure internal walls with high levels of sound resistance and absorption. They are not affected by dampness when suitably constructed.Hebel systems can achieve (and often exceed) BCA requirements and are extremely fire-resistant with thermal absorbing properties that assist in improved energy ratings for the building and have been independently certified as meeting the requirements of Good Environmental Choice Australia (www.geca.org.au)
Hebel. Proven, scientifically tested and trusted by leading builders
The Hebel system has a solid track record of trusted performance and reliability characteristics that make it the accepted industry standard in internal wall systems.
Building with the Hebel means simpler construction methods, delivers faster construction timetables and lowers risk of non-compliance to the BCA.
Australian made and backed by CSR Hebel is 100% manufactured in Australia by CSR Building Products Limited, so you can depend and rely on the product quality, technical expertise, ‘after sales’ service, warranty and stock supplies. In addition Hebel will help you manage the entire end-to-end process, providing technical support and ‘after sales’ on-site service to assist you so that your residential construction with Hebel is seamless and efficient.

Hebel. Better to build with…
At the heart of the Hebel system is the Hebel PowerPanel - a 75mm thick, steel reinforced building panel made from AAC (Autoclaved Aerated Concrete) supplied in lengths of 2400mm to 3300mm for standard widths of 600mm.
The unique Hebel attributes are best summarised with the Hebel ‘tick’ below:
Fastest masonry Intertenancy Wall System
PowerPanel Intertenancy Walls are fast to construct and require significantly less labour compared to traditional masonry construction techniques. Building with Hebel means a cleaner, safer work area during construction and less clean-up at completion of building.4
Lightweight yet solid and tough as concrete
Lightweight Hebel PowerPanels can be easily installed by a crew of 2 or 3.PowerPanel Intertenancy Walls also
provide a high degree of security with solid, steel reinforced PowerPanels between units. The ultimate masonry “party wall” system.
A comforting thought for a comfortable living environment
Hebel’s unique AAC construction provides superior insulation qualities for a masonry product. The unique
combination of thermal resistance along with thermal mass, make building with Hebel a smart choice for meeting Australia’s increasing building efficiency regulations.For unit owners, the thermal efficiencies of Hebel reduce the reliance on heating and cooling appliances – the combined effects of using a heater less in winter and fans or air conditioning less in summer can have a big impact on rising energy costs.
A sound reason for better acoustic qualities
Hebel pioneered the introduction of lightweight wall panels providing acoustic performance levels at or above Rw + Ctr = 50 in high rise multi-residential
buildings. BCA acoustic compliance is simple and easy to achieve with a system that has the benefits of lightweight construction with steel reinforced masonry between the walls.
Highly fire resistant for peace of mind and added security
Hebel is non-combustible and renowned for its highly fire resistant properties. PowerPanel Intertenancy Wall Systems have been tested at CSIRO and achieve a FRL (Fire Resistance Level) of 90 minutes.
Sustainability for a better world in the long term starts today
Hebel delivers a diverse number of environmental benefits over brick and concrete. In an independent Life Cycle Assessment (the leading methodology
used to quantify the environmental impacts of a product’s entire life) undertaken by Good Environment Choice Australia, in accord with international standard ISO 14 024, Hebel was found to have clear environmental benefits across all key environmental criteria.
To be awarded the label, products must have a 30% lower impact than alternatives. Hebel uses 61% and 64% less embodied energy and 64% and 55% less greenhouse gas emissions than the comparative products, concrete and brick veneer.
As environmental consciousness and social responsibility increases, Hebel is striving to exceed further to set new sustainability standards in building materials and residential living.
...for all the best reasons
With the attributes and benefits shown above this innovative and versatile masonry product provides confidence that Hebel is ideal for all Intertenancy Walls as detailed throughout the remainder of this Design and Installation Guide.5
