Our supplier

The Hebel brand was born in 1989, created by the leading Australian brand CSR. CSR is widely recognised as a prolific supplier of high quality building materials for residential and commercial construction applications. in 1989, CSR recognised that there was a gap in the Australian market for an alternative material to the standard masonry products available at the time. Committed to providing aerated concrete products for local builders, CSR created the CSR Hebel brand and built Australia’s first AAC manufacturing plant in Somersby, NSW. The production of Hebel AAC blocks and panels commenced at this plant in 1990.

Over the last 30 years, Hebel aerated concrete products have been used in an impressive portfolio of projects Australia wide including:

  • The Melburnian apartment complex in Southbank, Melbourne
  • The Nishi building in NewActon Precinct, Canberra
  • The Southern Sydney Freight Rail Line, Sydney
  • One Central Park apartments, Sydney

As Australia’s only manufacturer of aerated concrete products, Hebel is committed to the ongoing innovation of sustainable aerated concrete blocks and panels designed to improve peoples homes and businesses while being kind to the environment.

Why choose autoclaved aerated concrete cladding?

High strength performance

Hebel aerated concrete cladding products are reinforced with anti-corrosion steel to provide excellent structural capability and strength. AAC is a high strength product with one-quarter of the density found in regular concrete products.

Excellent thermal performance

Relative to traditional masonry and concrete products, aerated concrete cladding has high thermal insulation properties. As air itself is a poor thermal conductor, the air bubbles present in aerated concrete blocks and panels prevent heat from being easily transferred to the other side. AAC also has naturally airtight characteristics, allowing builders to create airtight building structures which help to prevent heat escaping.

Fast and easy installation

Aerated concrete blocks and panels manufactured by Hebel are lightweight and easy to handle. Installation of Hebel cladding can be performed quickly, allowing you to minimise on site labour costs and delight your clients with rapid construction. Hebel AAC cladding can worked using off the shelf tools for sawing, drilling, machining and nailing.

Sound insulation

AAC blocks and panels have excellent sound insulation properties. They are particularly effective in reducing mid to low frequency sounds thanks to the high surface mass and porous structure of AAC panels.

Ideal fire resistance qualities

AAC blocks and panels are among the highest-rated fire resistant building materials available in Australia. AAC will not explode and is non-combustible. Ideal for buildings in bushfire-prone areas, AAC products typically have high fire ratings and BAL ratings.

Designed for longevity

Like normal concrete, AAC blocks and panels are long lasting and durable. When used in conduction with an appropriate surface coating, aerated concrete cladding is resistant to moisture, rot and termite damage. It is able to withstand the harsh Australian elements better than many other comparable building materials.

Rigorously tested

Hebel are the aerated concrete experts. Their AAC block and panel products have undergone extensive and rigorous quality testing to ensure consistently high quality standards with low associated risks. All Hebel AAC panels are compliant with the Australian Standard for Reinforced Autoclaved Aerated Concrete (AAC), AS 5146.

A sustainable choice

Autoclaved aerated concrete blocks and panels help buildings meet NCC and state specific energy efficiency targets with its airtight and thermal insulation qualities. Using AAC blocks and panels can also help buildings to receive credits under sustainable building certificate programs and schemes such as:

  • GreenStar
  • LEED (Leadership in Energy and Environmental Design)
  • NABERS (National Australian Built Environment Rating System)

Eco-conscious clients will appreciate that autoclaved aerated concrete blocks and panels result in less embodied energy and emissions over time when compared to a normal concrete block or panel.

Non toxic

Hebel autoclaved aerated concrete blocks and panels do not contain any toxic substances and will not harbour or attract vermin.

Versatile applications

Hebel autoclaved aerated concrete blocks and panels have an extensive range of suitable applications. If you enjoy working with a consistent building material across projects, aerated concrete is not limited to cladding. AAC can be used for applications such as:

Autoclaved aerated concrete manufacturing process

AAC is used widely on construction sites all over the world, and the technology to produce commercial quantities of AAC was developed more than 70 years ago in Scandinavia. The raw materials used in AAC production are sand (silica), lime, cement and water.


The raw materials are mixed and combined with an expansion agent. Each manufacturer may differ in the expansion agent used, although small amounts of aluminium paste or powder are popular choices. Once mixed, the result is a semi-liquid product called ‘slurry’.


Manufactures use moulds to form AAC blocks or panels. If a reinforced panel is being created, the steel mesh reinforcement will be placed into the mould while it is empty. Any anti-corrosion coatings or similar protections are applied to the steel prior to this placement. Once the mould is suitably prepared, the slurry mix is carefully poured into the mould.

Chemical reactions

When the slurry is poured, a series of chemical reactions take place between the raw ingredients. These chemical reactions cause hydrogen to form, which then causes the slurry mix to rise in the mould. When the hydrogen gas dissipates, it leaves behind a large number of tiny, finely dispersed air pockets. These air pockets are the key factor for how AAC is so much lighter than traditional concrete, while remaining strong and retaining excellent thermal insulation properties. This stage is called the ‘pre-curing’ stage.


When the slurry has become more solid (but is still soft and malleable), it is removed from the moulds. The resulting product is cut as needed in order to ensure all panels and blocks are the correct size. Any waste created at this stage is recycled.


Finally, the now consistently sized blocks and panels are baked under high levels of heat and steam pressure. This hardens or ‘cures’ the mix, which is the final step in the AAC manufacturing process.

Sustainable manufacturing at Hebel

The manufacturing process of ACC is eco-friendly when compared to traditional masonry products commonly used in construction projects. All green waste from the pre-autoclaved Hebel products are returned to the green mix for reuse. AAC makes excellent clean fill and road base, so it is able to be easily recycled and repurposed post-autoclaving as well.

Hebel are committed to ongoing sustainability practices and innovation.
