Hebel: The Complete Guide  

Share this article

If you’re new to the construction industry, you may not have heard about Hebel. As expert Hebel installers in Sydney, our favourite go-to for our building projects is Hebel and for good reason too.  

What is Hebel?

Hebel is a strong, versatile and high-performance autoclaved aerated concrete (AAC for short) that comes in panel or block form. Manufactured by CSR Hebel in Australia, the benefits of Hebel are vast including quick  installation, energy efficiency, and high performance.   

But before we get started, who are the people that manufacture and make Hebel installation possible? 

Who is CSR?

CSR Hebel is a leading Australian AAC (autoclaved aerated concrete) manufacturer and a trusted name in the building products industry with over 30 years in the game.   

 Now that we know the manufacturer of Hebel, let’s delve into the manufacturing process!  

What is Hebel made of?

Hebel is made from a mix of natural, raw materials including cement, sand, lime, gypsum, and a small amount of aluminium powder which are combined with water and an expansion agent to produce a ‘slurry’ mixture. The mixture is then poured into moulds. This combination allows the concrete to rise (similar to bread dough rising), resulting in versatile and strong, yet lightweight concrete blocks and panels containing air pockets that help with sound and heat insulation.   

The high-quality finished product (made almost 80% of air!) is perfect for solid foundations and can be easily carved, sculpted or cut, meaning it is an extremely versatile building material. But don’t let its lightweight name fool you, a standard Hebel panel is equivalent to 75 bricks and is as solid as any brick and mortar it’s stacked up against! Hebel is made into large panels containing an anti-corrosion steel reinforcement for added strength and maximum durability, perfect for external cladding that is often exposed to the elements.

Which is better, Hebel or Brick?

The debate between  Hebel vs brick has been a hot topic in the construction industry. There’s no denying Aussies love their brick houses but there is also no denying that just because something works it does not mean it’s the best option.    

Both Hebel and brick are great options and have their benefits. They are both durable and strong.   

However, Hebel provides additional advantages over traditional brick. Hebel offers all the benefits of brick while being easy and quick to install. It cuts the house construction time significantly, reducing the expense associated with tradies on site. Hebel, as compared to bricks, also does not have weep holes that stop pests and moisture from entering your home.    

Hebel is an eco-friendly premium building material that offers energy efficiency, flexibility and high performance. It is perfect for soundproofing and is a cost-effective choice.   

Sure, brick provides a classic design aesthetic, but Hebel offers a modern, clean look much more suited to today’s market. It is for these reasons experts are choosing Hebel over traditional bricks and mortar.    

To us, it is no surprise Hebel is fast taking over from traditional methods, it is one of the most innovative products on the market. Although, both brick and Hebel are staples in the construction industry and are strong options for you to consider.   

Where can I use Hebel?

Hebel’s high-quality external wall system is perfect for solid foundations and can be easily carved, sculpted or cut, meaning it is an extremely versatile building material.  

 These strong, versatile and solid Hebel panels are fixed to the frame of your home and assist in the construction of the façade, sides and rear external walls. Hebel is extremely robust and is a fantastic option for attaching weight-bearing external add-ons such as a pergola, shade areas, washing lines, or even a basketball hoop.   

It is a common misconception that brick is a better option for external structural add-ons than Hebel. However, this is not true, as both materials have similar impact resistance. In fact, Hebel’s strength and durability are fortified by the presence of anti-corrosion steel reinforcement. This reinforcement helps to maintain the solidity of Hebel, making it a reliable and robust building material for a range of construction applications.

Benefits of Hebel: What makes Hebel so special?

Hebel is a great building material and comes with a huge range of benefits that makes it stand out. The 10 Hebel benefits include (but are not limited to):

1. Solid and strong  

Hebel’s Autoclaved Aerated Concrete (ACC) containing an anti-corrosion steel reinforcement is solid and strong delivering high performance, maximum strength, durability and resilience.

2. Thermal efficiency   

Hebel panels achieve high energy efficiencies for homeowners. They use high thermal mass stores, which reduces energy usage over time. Hebel panels are excellent insulators, keeping homes cool in the height of the Australian summer and warm in the cool of winter. These great thermal efficiencies help you reduce utility bills by relying less on air conditioning or heating units, which in turn is also better for the environment. Some cool benefits and hot savings indeed!

Hebel is known for its excellent insulation properties, which can help to keep buildings cooler in summer and warmer in winter. In fact, some experts claim that Hebel can provide up to six times more insulation than brick. Here’s why:

Hebel has a 77mm thickness with a 0.52 R-value rating, compared to a 110mm brick with a 0.18 thickness and 0.18 R-value. That’s a 2.88 x more R rating than traditional brick which makes a home more energy efficient. Bricks just don’t stack up.

3. Noise reduction & insulation.   

Hebel is not only great for improving thermal efficiency but also offers excellent soundproofing and acoustic insulation properties. Its soundproofing capabilities are due to its construction and higher R-rating. Hebel is versatile and can be used in a range of applications, including dual occupancy developments and double-storey home builds. It is particularly useful for homes or businesses built near busy motorways, as it provides a practical solution to traffic noise.   

The Hebel flooring system, Hebel Powerfloor offers a solid flooring solution minimising noise transference from neighbouring rooms and floors. It also adds a fire-resistant layer and can even be installed under timber, carpet or tiles. Hebel Powerfloor is a sound foundation for floor laying and a sound investment.    

4. Fire-resistant   

This brings us to another great benefit of Hebel; fire resistance. Hebel achieves a high BAL (Bushfire Attack Level) rating and has been tested by CSIRO (Commonwealth Scientific and Industrial Research Organisation) to meet and exceed the six BAL categories. This ensures Hebel is an ideal building material for bushfire-prone zones with termite-resistant, non-combustible, and fire-resistant properties.    

5. Environmentally friendly   

Hebel is made from readily available recyclable raw materials and is economical compared to poured concrete or a traditional rendered finish making it an environmentally friendly product. Made in Australia, it is an environmentally smart choice to help combat Australia’s wild climate. Hebel goes one step further by recycling both the waste generated in the manufacturing process and even the steam it produces.  

Hebel is a great option for both your pockets and the environment – and for good reason! With over 30 years of testing, developing, manufacturing and perfecting you are guaranteed high-quality Hebel building products and systems. It goes without saying their fire resistance, soundproofing, and thermal efficiency are a strong choice for fast and quality construction throughout Australia.    

6. Fast Construction   

Building great homes and great construction relationships, Hebel is lightweight, flexible and easy to cut. As one large Hebel panel is equivalent to 75 traditional bricks it’s perfect for fast construction without sacrificing quality. Hebel is a great building product to work with allowing easy handling and quick installation. Hebel doesn’t cut corners but makes it easier to cut holes and chases for electrical and plumbing lines, cutting the time and effort for faster construction.   

7. Design flexibility/stylish design    

Let’s face it, first impressions count. The street appeal of a home is not only significant for personal satisfaction but also for its potential resale value. The design of homes has progressed with time, and so has house rendering. Popular TV shows such as The Block or Love It or List It Australia shows the shift toward partially or fully rendered houses

 In today’s world, bricks may no longer be the preferred choice when it comes to selling, renting, or designing a home’s facade. The appearance and overall aesthetic of a house cannot be overstated when attempting to create impact, street presence, and visual interest.   

Sure, you can paint or apply render to your bricks, but a Hebel façade has the advantage of a fully rendered, modern, fresh, and sleek finish from the get-go. Hebel cladding provides the flexibility to express personal style and is a perfect addition to a house design with a wide range of Dulux colours and show-stopping facade options.   

Hebel is the height of style and functionality and is designed to complement other design features such as stunning porch tiles, weatherboard cladding, and other external design options. It is a perfect addition to many home designs including contemporary or French provincial elegance, it has a place in any stylish design, adding stunning visual impact and street appeal.   

What’s more, if you choose not to render your brick post-construction, it is easier to repaint Hebel than change the brick colour which can help save you the cost of labour and added materials in the long run.   

8. Affordability   

This brings us to affordability. Hebel is a cost-effective choice for anyone looking to reduce build costs, utility bills and maintenance costs. The old “one standard panel being equivalent to 75 traditional bricks” statement rears its head again, why? Because this makes building and installation quicker. A quicker, easier build equals fewer labour costs.   

What’s more, Hebel has the added benefit of being a long-lasting, low-maintenance option.   

9. Maintenance   

How is Hebel low maintenance?

As Hebel is long-lasting, an annual low-pressure water blast is all it takes (6 months in coastal areas) to remove dirt and get it looking clean and fresh. Although we do recommend you repaint it every 7 to 10 years, especially with light-coloured Hebel renders.

No weep holes

You will also notice that compared to brick Hebel has no weep holes, where pests such as cockroaches, mice, or wasps can get through.

There have been many debates on if Hebel is higher or lower maintenance than brick and both have their advantages and disadvantage. For example, Hebel can look dirty after a few years and need painting.
