When it comes to energy efficiency and comfort, insulation plays a critical role in Western Australian homes. As a premier insulation installer, Insulation Extract ensures compliance with the latest standards while helping homeowners optimise their energy efficiency. Here’s what you need to know about insulation requirements in WA, based on current regulations and guidelines.
Legal Requirements: The National Construction Code (NCC)
The National Construction Code (NCC) governs insulation standards across Australia, including Western Australia. Under the NCC, new homes must meet minimum energy efficiency standards:
• R-Value Requirements: R-values measure thermal resistance, with higher values indicating better insulation.
For WA’s climate zones, R-values for roofs, walls, and floors vary but typically aim to combat both heat gain in summer and heat loss in winter. These R-values may change over time; however, we stay informed about these updates and ensure that your new insulation consistently meets or exceeds the latest minimum requirements.
• Star Ratings: Residential buildings must achieve at least a 7-star energy rating under the Nationwide House Energy Rating Scheme (NatHERS). This accounts for insulation, windows, and other construction elements.
• Deemed-to-Satisfy Provisions: Builders can meet compliance through elemental provisions (e.g., specific material choices and installation standards) or energy rating tools.
Choosing the Right Insulation
Insulation Extract offers a wide range of insulation solutions in which there are three primary types to consider:
• Earthwool Batts: Made using up to 80% recycled glass and with ECOSE® Technology, bio-based binder that contains no added formaldehyde.
• Fibrous Glass Mineral Wool: Designed for installation into existing and new cavity wall systems which significantly increases the thermal and acoustic performance of the wall. Using Glasswool insulation material that is non-combustible, silicon treated for mould protection.
• Polyurethane Sprayfoam: A material that is sprayed onto surfaces in liquid form, then expands and hardens into a dense, airtight foam. It offers superior insulation performance compared to other materials.
At Insulation Extract, we assess your home’s needs and recommend the most suitable materials based on WA’s specific requirements.
Installation Best Practices
Key considerations include:
• Maintaining R-Value Integrity: Insulation must remain continuous and uncompromised by gaps or compression around fixtures.
• Ventilation: Adequate ventilation in roof spaces prevents moisture buildup and maintains insulation effectiveness.
• Thermal Breaks: For metal-framed buildings, thermal breaks prevent heat transfer between external and internal environments.
Proper installation is as critical as the insulation material itself which is why the installation is best left to professionals. At Insulation Extract we specialise in insulation installations and incorporate all key considerations into our insulation practices.
The Benefits of Compliance
Meeting insulation standards isn’t just about compliance; it offers tangible benefits:
• Energy Savings: Proper insulation can cut heating and cooling costs by up to 45%.
• Comfort: Insulation helps maintain stable indoor temperatures year-round.
• Environmental Impact: Energy-efficient homes contribute to Australia’s net-zero emissions goals.
