Exterior Insulation and Finish Systems
Components of Exterior Insulation and Finish Systems (EIFS)
Advantages of EIFS
It’s important to note that EIFS requires proper installation and maintenance to prevent moisture-related issues, such as water intrusion or mould growth. It’s worth noting that proper installation and maintenance are crucial for the long-term performance of EIFS. Therefore, it’s important to consult with qualified professionals familiar with EIFS installation guidelines and best practices.
External Cladding Systems in Australia
In Australia, the rules and regulations for external cladding systems are primarily governed by the National Construction Code (NCC), which consists of the Building Code of Australia (BCA) and the Plumbing Code of Australia (PCA). The NCC is a performance-based code that sets out the minimum requirements for the design and construction of buildings.
Specific requirements for external cladding systems can vary depending on factors such as the height and type of the building, its location, and the materials used. The following are some key considerations and regulations related to external cladding systems in Australia:
The NCC places significant emphasis on fire safety. The BCA has introduced strict requirements for the fire performance of external cladding materials. This includes restrictions on the use of certain types of combustible cladding materials in high-rise buildings and requirements for testing and certification of cladding systems.
The NCC outlines specific performance requirements for external cladding systems related to structural integrity, weatherproofing, and resistance to moisture penetration. These requirements ensure that cladding systems are durable, provide adequate insulation, and protect the building from external elements.
Building practitioners and contractors are required to ensure that the cladding systems used comply with the relevant standards and regulations. Certification and documentation demonstrating compliance may be required, particularly for high-rise buildings or those subject to additional scrutiny due to their location or design.
While the NCC provides a national framework, each state and territory in Australia may have its own additional requirements or guidelines for external cladding systems. These variations can relate to specific materials, installation methods, or additional testing and certification processes. It is essential to consult the relevant state or territory authority to ensure compliance with local regulations.
In response to concerns about existing buildings with non-compliant cladding systems, many states and territories have implemented programs to identify and rectify buildings with potentially hazardous cladding. These programs often involve inspections, assessments, and requirements for remediation or replacement of non-compliant cladding.
*It is important to note that building codes and regulations are subject to updates and revisions. To ensure compliance with the current requirements, it is recommended to consult the most recent edition of the NCC and any relevant state or territory variations. Additionally, engaging with local councils and authorities during the design and construction process is crucial to understanding any specific requirements or guidelines that may apply in a particular area.
EPS Cladding and the Environment
- EPS Cladding is comprised of 98% engineered air and therefore only 2% polystyrene, making it a highly efficient use of raw material.
- No CFC’s or HCFC’s foam agents are used in its manufacture, so EPS causes no damage to the ozone layer.
- Effective installation of EPS Cladding can cut carbon dioxide emissions by up to 50%.
- The R-value of EPS Cladding does not deteriorate during its lifetime, therefore the reduction in emissions lasts the full lifetime of the building.
- The energy used to manufacture EPS Cladding is recovered within six months by the energy saved in the building in which EPS Caldding is installed.
- Typically, for every kg of oil used in EPS Cladding manufacturing, around 200kg will be saved in reduced heating demands.
- All EPS waste is recycled. It can be granulated and mixed with virgin material to make new products, or melted down to create alternative products in other industries.
