Hebel Research Part 1

The History of Hebel

In 1920s, the deficit of wood in Sweden causes people need to find other building materials instead of wood. Johan Ericksson, Swedish architecture, had many experiments with aerated concrete. Aerated concrete was a constant improvement on conventional bricks which reduces its fragile and precarious properties, and eventually he invented autoclaved aerated concrete also called Hebel.

After that, Josef Hebel, who owned a German factory, to further improve Hebel, he used the manufacturing processes for Hebel using all recycled excess material and waste, making it one of the world’s first environmentally friendly manufactured products.

The production of Hebel was relatively slow, but the industry in China, Central Asia, India, and the Middle-East needs high demand in some areas such as housing and commercials. Therefore, the industry in those countries was growing quickly.

The Uses of Hebel

Hebel can be used for both internal and external construction. When building a house with Hebel, Hebel is really a good material, because Hebel is fast to build with, cuts out noise and is a great insulator; and it creates a quieter and more comfortable living environment for residents. When building fences or exterior of apartment, Hebel is a simple and convenient material to use. It is easy to install, extremely lightweight, and steel reinforced.

The Benefits of Hebel

1) Effective Cost and Construction Times Saving
Hebel is a beneficial building material which is solid and inexpensive. It can be cut easily by using standard tools, save construction times and minimizes the generation of solid waste during use. The result is lower labour costs and significant savings for the homeowner. 

2) Similar Resistance to Traditional Brick
Hebel panels provide people a sense of security similar with traditional and common clay bricks. In fact, they both use claw hammer to increase their resistance. The steel reinforced Hebel internal walls also add strength and security between rooms compared to plasterboard systems.

3) Superior Insulation Qualities
Hebel panels have superior insulation qualities compared to other masonry products. With better thermal resistance and thermal mass, Hebel is a smart choice for meeting Australia’s stringent building regulations. And, for homeowners, it means there is less reliance on heaters or air conditioners – helping to save money and being kinder to the environment.

4) Environmental Benefits
Hebel offers lower environmental impact in all phases of its life cycle, from processing of raw materials to the disposal of waste. The assessment, undertaken by GECA in accordance with international standard ISO 14 024, shows Hebel is a much greener option for building. It has 61% and 64% less embodied energy than concrete or brick veneer, respectively; and 65% and 55% less greenhouse gas emissions.

5) Effective Sound Insulation
Hebel has better acoustic qualities, giving people more quiet and peace environment. When compared to polystyrene and many fibre cement external walls, and particleboard for flooring, Hebel's unique building material significantly reduces sound transmission between rooms and reduces the noise from external sources, like traffic.

6) Superior Fire Resistance
Hebel has porous structure which allows for superior fire resistance. A non-combustible material, Hebel's block and panel systems achieve Fire Resistance Levels (FRLs) from 60 minutes through to 240 minutes (tested at CSIRO) and meet or exceed the requirements for all six Bushfire Attack Level (BAL) categories. When building with Hebel, you’re building with peace-of-mind that your home is safe and secure.
