As New Zealand’s building code evolves, staying compliant with H1 Energy Efficiency standards is more important than ever.
At Bradford, we’ve made it simple to meet these requirements—while also helping you create a home that’s cooler in summer, warmer in winter, and more energy efficient all year round.
In 2020, the government introduced updated thermal performance requirements under H1/AS1 and H1/AS2, aiming to make buildings up to 40% more energy efficient. These changes affect how insulation is specified and installed, especially in new homes and buildings under 300 m².
Keeping you covered
Bradford’s BRANZ Appraised insulation products are designed to meet or exceed these standards, offering tailored solutions to suit your build, such as:
- Double Layer System: A high-density R1.8 layer between the joists, topped with R5.2 insulation for maximum thermal performance.
- Over-the-Top System: A single layer of R7.3 insulation laid over the joists, creating a continuous thermal barrier.
