In 2020 the NZ government updated the thermal performance requirements for insulation.
The new standards, called H1 Energy Efficiency Acceptable Solution H1/AS1 apply to new homes and buildings up to 300m². Requirements for buildings over 300m² have been combined into the new Acceptable Solution H1/AS2.
The new standards are designed to make our buildings warmer, drier and up to 40% more energy efficient.
As Aotearoa NZ heads into our colder season, it's a great time to consider compliance and comfort.
Not only does Bradford have a comprehensive range of BRANZ Appraised insulation products that meet or exceed New Zealand Building code standards, Bradford Gold insulation products are also Sensitive Choice certified for people with asthma and allergies.
Before a product or service is approved by Sensitive Choice, it is reviewed by an expert panel who considers whether it is suitable to carry the Sensitive Choice Blue Butterfly on collateral and packaging. The Panel reviews evidence to determine that a product or service is not harmful and demonstrates a potential benefit for people with asthma or allergies, before making a recommendation.
With H1 changes also in play this season, be confident in your NZBC compliance with Bradford's H1 focused products:
- For the double layer solution, a High Density R1.8 product is installed between the joists, then R5.2 product is laid over the top.
- For the single layer option, over the top of joists, R7.3 product is installed.
- For the single layer option, in between the joists, Bradford have developed and tested a thicker product. R7.3 (450mm wide) which is installed in-between the joists, then spills over the top to cover the joists.
Bradford comprehensively tests its glasswool segments for thermal performance. If you would like to review Bradford's test certificates and product warranties you can contact Bradford directly.
