You need to know about some important changes to the building standards covering roof and wall claddings.
The revised standard is known as AS 1562.1:2018 Design and Installation of Sheet Roof and Wall Cladding – Metal. It replaces AS 1562.1—1992.
Compliance with the new Australian Standard is mandatory for all new building projects. It’s part of a constant drive to improve the durability and weathertightness of homes in Australia.
AS 1562.1—2018 provides updated detail on best practice design and installation techniques for metal roofing (including metal tiles) and wall cladding.
Most of the new changes relate to engineering specifics such as material quality and fastening techniques.
The revised standard also covers important load bearing aspects such as frictional drag in wind, and material behaviour under snow loadings and it is applicable to both cyclone and non-cyclone regions.
Although the revisions may apply to specific types of cladding such as metal faced structural insulated panels (SIPS), other types such as stressed-skin design (diaphragm action) claddings are excluded.
Although the NCC (National Code of construction) adheres to a 3-year cycle of updates, revision of specific standards is a constant ongoing process.
This latest iteration of AS 1562.1—1992 is one of a number of recently revised standards that have become part of the building code.
These changes are now an essential part of any design and installation work for new buildings.
It’s vital that architects and designers are conversant with the new standards and that they ensure that all cladding types chosen meet these new requirements.
Failure to stipulate the required products and structural and engineering features may lead to costly delays through the Council approval process and necessitate expensive design changes.
These types of delays can quickly blow out budgets and hold up other essential processes within a build.
This increases stress levels for all involved and creates considerable customer dissatisfaction.
You can avoid these unnecessary complications by working with a supplier who provides only certified and approved cladding, and architectural panel system types.
The revised AS 1562.1:2018 Design and Installation of Sheet Roof and Wall Cladding – Metal standard is essential reading for all people involved with the supply, design and construction of metal roof and wall cladding.
This includes:
- Architects & designers
- Plumbers & roofers
- Builders & developers
