Autoclaved aerated concrete (AAC) is a solid yet lightweight building material that’s widely used in construction throughout the world. The technology to manufacture AAC was developed in Scandinavia over 70 years ago.

In the AAC manufacturing process water and readily available dry ingredients – sand, lime and cement – are mixed with an expansion agent to form a semi-liquid mix called slurry which is poured into a mould. If panels are being produced then steel mesh reinforcement will be appropriately placed in the mould before the slurry pour.

Chemical reactions occur between the ingredients causing hydrogen to form, which in turn causes the slurry to rise. This is called the pre-curing stage. The hydrogen gas then dissipates leaving extremely small, finely dispersed air spaces. This is the essence of why AAC is much lighter than traditional concrete, yet strong and solid with excellent thermal properties.

The solid but still soft mix is separated from the mould and cut to form the right-sized blocks or panels for the batch. Any waste is recycled. The manufacturing process doesn’t stop there however. The uncured AAC panels are ‘baked’ under elevated heat and steam. The blocks and panels are ready when they’re hardened or cured.

• Strong and solid: Hebel panels are high-performance products containing steel reinforcement for added strength with an anti-corrosion layer on the steel for maximum durability.
• Quality and speed: Building with Hebel can mean faster construction times, without sacrificing on quality. One standard Hebel panel is the equivalent of 75 traditional bricks, which means a 150m2 home can go up as quickly as within 3 days when installed by experienced Hebel installers. A high quality building material, Hebel provides a great solution in terms of speed and ease of construction which is why it is increasingly becoming the builder’s choice.
• Energy efficient: Hebel panels perform well thermally, helping to keep your house cool from the heat in summer, and keeping it warm and cosy in winter. That means less reliance on heating and cooling, and can lead to savings on energy costs.
• Noise Reduction: A Hebel home is a quiet one because it reduces noise transmission. The use of Hebel for external walls reduces noise from external sources like traffic and when used for upper floors, can reduce sound transference between levels as well.
• Fire Resistant: Hebel is renowned for its fire resistant properties, and is a non-combustible building material. Hebel systems have been tested by the CSIRO and are proven to achieve Fire Resistance Levels (FRLs) of 60 minutes through to 240 minutes, and meet or exceed the requirements for all six Bushfire Attack Level (BAL) categories. This makes it an ideal choice in bushfire zones.
• Proven: CSR Hebel is the only manufacturer of AAC in Australia. With over 30 years of experience in developing, testing and producing AAC you can be assured you’re getting high quality products and systems and unmatched technical expertise with Hebel. Hebel AAC includes a range of Australian made and imported product. Hebel imported products are manufactured on our behalf to Australian standards, and undergo the same rigorous quality testing.
