Knauf Insulation Product certifications
CodeMark™ provides confidence to regulatory authorities and end-users that certified products meet the requirements of the New Zealand Building Code.
Legislation requires building approval authorities to accept CodeMark™ certificates as evidence of compliance with the Building Code. We have selected CodeMark™ certification to provide compliant support systems that are new to the market.
BRANZ is an independent and impartial research, testing and consulting organisation that has an in-depth knowledge of the New Zealand Building Code.
We use BRANZ Appraisals to demonstrate compliance with the Building Code requirement, AS/NZS 4859.1 thermal requirements and to demonstrate that the products are fit for use.
All glasswool products manufactured by Knauf Insulation are made of non-classified fibres (fibres that are less bio-persistent than every day dust) and are certified by EUCEB. EUCEB, European Certification Board of Mineral Wool Products - www.euceb.org, is a voluntary initiative by the mineral wool industry. It is an independent certification authority that guarantees that products are made of fibres, which comply with the exoneration criteria for carcinogenicity (Note Q) of the Regulation (EC) 1272/2008. To help user’s identify the safety of our glasswool fibres the EUCEB logo is displayed on our product packaging and/or labels.
Eurofins “Indoor Air Comfort” (IAC) product certification is an innovative tool to show compliance of a product with low VOC emissions.
Earthwool® glasswool is certified as achieving a Gold Standard – this is the broadest standard available today that meets all existing criteria with regards to Indoor Air Quality.
Non-combustible is a defined term in the New Zealand Building Code. The compliance of a material to the New Zealand Building Code non-combustibility definition can be determined by conducting an AS 1530.1 standard combustibility test.
If the material satisfies the criteria outlined in the test method the material is not deemed combustible. Knauf Insulation products have been independently tested in NATA accredited laboratories; giving end users confidence in the standard of the test and procedures.
GreenTag™ is a third party, green building product rating and certification system putting certified products within the top end of the green product market.
The certification makes it easy for designers and building owners to gain rewards under Green Star and Homestar credits system. Earthwool® glasswool is the first and only glasswool insulation in New Zealand to have GreenRate™ Level A certification.
The ILAC Mutual Recognition Arrangement (ILAC MRA) provides significant technical underpinning to the calibration, testing, medical testing and inspection results, provision of proficiency testing programs and production of the reference materials of the accredited conformity assessment bodies that in turn delivers confidence in the acceptance of services and results. Knauf Insulation’s laboratory has demonstrated its technical competence to operate in accordance with MS ISO/IEC 17025:2017 (ISO/IEC 17025:2017), means the laboratory meets both the technical competence requirements and management system requirements that are necessary for it to consistently deliver technically valid test results and calibrations.
Earthwool® glasswool compliance with EECA
The Energy Efficiency and Conservation Authority (EECA) maintains a List of Accepted Insulation Products that may be installed under the New Zealand government’s Warmer Kiwi Homes program, and under voluntary targeted rate schemes of local councils. The process and criteria applied by EECA for assessing whether insulation products – ceiling, wall and underfloor insulation – are eligible for inclusion in EECA’s List of Accepted Insulation Products is set out in EECA’s Insulation Product Approval Policy.
New Zealand Building Code
New Zealand has a comprehensive Building Code and all building work in New Zealand must comply with its requirements. This ensures buildings are safe, healthy and durable for everyone who may use them. The Building Code sets clear expectations of the standards buildings should meet. It covers aspects such as structural stability, fire safety, access, moisture control, durability, services and facilities, and energy efficiency. Every material used in construction must comply with relevant clauses and this section has been designed to show the compliance of our glasswool products.
