Dahlsens supplies some of Australia’s leading AAC panel systems, including Hebel, Helix AAC and James Hardie Gravis™ Panel.
But what’s the difference?
While all offer the key benefits of AAC construction, there are differences in their product ranges and pricing.
Here’s how they compare.
Hebel vs Helix vs Gravis at a glance
What is an AAC panel?
| Hebel | Helix AAC | James Hardie Gravis | |

| Product range | Extensive | Focused | Focused |
| Brand | Hebel / CSR | Helix | James Hardie |
| Ideal when | You need broader AAC system options | You want a quality, value-focused AAC solution | You use James Hardie products across the build |
An AAC panel is made from autoclaved aerated concrete, a lightweight concrete building material containing millions of tiny air pockets.
AAC concrete panels can be used to create external walls and other building systems, depending on the specific product.
Why use AAC panels for building homes?
Builders choose AAC because it can combine lightweight construction with thermal, acoustic and fire-performance benefits. Its larger panel format can also provide an efficient alternative to traditional brick construction.
Helix AAC: high performance and great value
Helix AAC provides builders with a quality AAC option, particularly for metropolitan residential construction.
Its key advantage is value.
For builders who want the benefits of an AAC external wall system at a competitive trade price, Helix offers a focused, high-performance solution.
This can make Helix AAC particularly attractive for detached homes, townhouses and volume residential projects where builders need to carefully manage their construction costs.
Choosing great value doesn’t mean abandoning the reasons builders choose AAC in the first place. Helix systems are designed to provide the thermal, acoustic, fire and durability characteristics expected from quality AAC construction.
Why choose Helix AAC?
Helix may be a good choice when you want:
- A quality AAC wall system
- CodeMark certified
- Strong thermal and acoustic performance
- Competitive project pricing
- A practical solution for metro residential construction
- Good value without moving away from AAC construction
For many residential projects, Helix offers a strong balance between performance and price.
James Hardie Gravis: AAC from a trusted cladding brand
James Hardie Gravis™ Panels bring another major Australian building-products name into the AAC category.
The biggest point of difference is the James Hardie ecosystem.
Builders already using James Hardie fibre cement products can incorporate James Hardie Gravis panels alongside other James Hardie cladding products, making it easier to create homes featuring multiple façade finishes.
For example, a design might combine rendered Gravis James Hardie AAC walls with fibre cement weatherboards or architectural panels.
This makes Gravis particularly appealing to builders, designers and homeowners who already know and trust James Hardie products.
Why choose James Hardie Gravis?
Gravis may suit your project when you want:
- AAC backed by the James Hardie brand
- Compatibility with James Hardie fibre cement cladding
- Different façade materials from one recognised supplier
- A modern rendered AAC wall system
- A straightforward residential AAC solution
- CodeMark certified
Hebel: the established Australian AAC option
Hebel is one of Australia’s best-known AAC brands and is part of CSR.
One of its biggest advantages is its established product range. While AAC is often associated with detached and multi-residential homes, CSR Hebel Australia offers systems suitable for residential, multi-residential and commercial construction.
Products include Hebel PowerPanel systems for external walls, along with other wall and Hebel flooring solutions.
This makes Hebel particularly useful where a project requires more than a standard residential external wall system.
Another important difference is local manufacturing. Hebel panels are manufactured in Australia, making Hebel an attractive choice for builders and developers who value Australian-made building products and an established local brand.
Why choose Hebel?
Hebel may be the better choice when you want:
- An established and trusted Australian AAC brand
- Australian-made AAC products
- A broad range of wall and flooring systems
- Solutions for multi-residential or commercial projects
- An AAC system with a long history in the Australian construction market
- CodeMark certified
For larger or more complex developments, the breadth of the CSR Hebel range can be particularly valuable.
Hebel vs Helix vs James Hardie Gravis: which should you choose?
Choose Hebel if Australian manufacture, brand history or access to a wider range of Hebel wall, Hebel PowerPanel and Hebel flooring systems is important. It is particularly worth considering for commercial applications.
Choose Helix AAC if you’re building in a metropolitan residential market and want a quality, high-performance AAC concrete panel system with competitive pricing.
Choose James Hardie Gravis if you value the James Hardie brand or you’re combining AAC with James Hardie fibre cement cladding across the project.
There isn’t one AAC system that’s best for every project. The right choice comes down to the type of build, required system, budget, design and project requirements.
What about Hebel vs brick?
The choice isn’t limited to different AAC brands. Builders also frequently compare Hebel vs brick or Hebel vs bricks when selecting an external wall system.
AAC panels can provide a faster, lightweight alternative to masonry while delivering strong thermal, acoustic and fire performance. For projects that will ultimately have a rendered finish, AAC can also remove some of the additional stages involved in constructing and rendering a traditional brick wall.
The right option will depend on the design, engineering, required wall performance, installation costs and availability of trades.
