What is lightweight construction?

Share this article

​In lightweight construction, timber or light gauge steel framing provides structural support for the building. Non-structural cladding – made from lightweight building materials such as autoclave aerated concrete (AAC) e.g. Hebel, or polystyrene panels eg: Exsulite, to name just a couple of examples – is then attached to the framework.

A proven product, AAC has been used as a building material in Europe for more than 70 years, and in Australia for over 20 years.

AAC is made by mixing an expanding agent to concrete, causing tiny air bubbles to form. The cement is then cured in a heated environment, and while soft, sliced to size. The panels or blocks that are formed are steam cured in an autoclave, making them strong and contributing to their much valued thermal and acoustic capability.

AAC, along with other more recent innovations in lightweight building materials, such as polystyrene and other such external claddings continue to evolve to deliver substantial advantages to builders and the people who will inhabit the building once completed.

Each type of lightweight construction product offers different features and benefits. Materials are available in different formats including block and panel forms.
