FAQ
Yes. Helix is a steel-reinforced autoclaved aerated concrete (AAC) panel system. Helix AAC wall panels are available in 50mm and 75mm options for approved wall-system applications.
An AAC panel is a lightweight concrete building panel made from autoclaved aerated concrete. The aerated structure contains many small air pockets, reducing weight while providing useful thermal, acoustic and fire-performance characteristics. AAC panels are commonly used in residential and multi-residential wall systems.
An aerated concrete panel is another way of describing an autoclaved aerated concrete, or AAC, panel. AAC is a lightweight cementitious material formed with a cellular structure and cured under pressure in an autoclave. Helix AAC is a steel-reinforced aerated concrete panel system.
An AAC wall is a wall system constructed using autoclaved aerated concrete panels or blocks together with the specified framing, fixings, joints, coatings and other system components. AAC walls are commonly used for external facades and, where certified, intertenancy or other specialist wall applications.
AAC panels are used for wall and, in some product systems, flooring applications. Common uses include external walls, rendered facades, boundary or zero-lot walls, intertenancy walls and multi-residential construction. Helix should be selected according to its current approved wall-system documentation.
Helix AAC panels are used in approved residential and multi-residential wall systems, including external rendered facades. Current Helix documentation also includes intertenancy and party-wall systems. Always confirm the relevant system guide for the application.
Helix AAC wall panels are 600mm wide and available in 50mm and 75mm thicknesses. Available lengths vary by thickness and stock holding, so confirm current sizes and availability with Dahlsens.
The appropriate Helix panel thickness depends on the specified wall system, application and project performance requirements. Refer to the current Helix technical documentation or speak with a Dahlsens AAC specialist before selecting a panel.
Helix AAC panels are made from non-combustible autoclaved aerated concrete. Fire performance and any required fire-resistance level depend on the complete certified wall system and application, so current Helix documentation must be checked for the project.
Yes. Helix AAC panels provide a smooth substrate for compatible render and coating systems, making them well suited to contemporary rendered facades. Use a compatible system and follow the current manufacturer specifications.
Yes. AAC stands for autoclaved aerated concrete, so AAC panels are a type of concrete panel. Unlike dense conventional concrete, AAC has a cellular structure containing air pockets, making the panels substantially lighter and giving them different thermal and acoustic characteristics.
AAC panels and brick are both masonry-style external wall options, but they use different construction methods. AAC uses large-format lightweight aerated concrete panels fixed as part of a proprietary wall system, while brickwork is built from individual masonry units. AAC can reduce wall-system weight and support faster installation, while the best option depends on design, specification, trades, finish, budget and project requirements.
AAC panel systems are commonly specified as an alternative external wall construction to traditional brickwork on suitable projects. The wall system still needs to meet the project’s structural, fire, thermal, acoustic, weatherproofing and finish requirements, so builders and designers should select a certified system appropriate to the design.
The Helix material supplied for this page supports 50mm and 75mm AAC wall panels. It does not identify a dedicated Helix AAC floor panel. If your project requires AAC floor panels, talk to Dahlsens about an AAC flooring system that is specifically designed and documented for flooring applications.
AAC floor panels are reinforced autoclaved aerated concrete panels specifically engineered as part of a structural or suspended flooring system. Flooring products should not be substituted with wall panels; use a dedicated AAC floor system and follow its current engineering and installation documentation.
Helix AAC wall systems have CodeMark certification available. Always use the latest certificate and technical documentation to confirm the certified system, scope and requirements that apply to the project.
AAC is non-combustible and Helix can form part of wall systems used in bushfire-prone construction. Suitability for a particular BAL and project depends on the complete certified system and design, so check the current Helix documentation and project requirements.
