At JMF, we provide New Zealand’s most comprehensive range of NZS: 4211 compliant timber joinery, including doors and windows that have been thoroughly tested for quality and durability. Since our inception in 2012, our network of independent manufacturers has delivered high-performance joinery solutions to homes across the country. With over 130 manufacturers, from Kaitaia in the North to Invercargill in the South, we have the reach and expertise to meet the needs of any project.

Whether you’re renovating a heritage villa or building a modern architectural home, JMF timber joinery offers a range of solutions tailored to your project. Not only is timber joinery visually appealing, but it’s also the top choice for enhancing thermal performance, helping to keep Kiwi homes warmer, drier, and healthier.

Your Legal Obligation as a Manufacturer: If you manufacture timber doors and windows in New Zealand, it’s crucial that your products comply with the New Zealand Building Code. The Building Code includes several clauses specifically relating to doors and windows, such as:

• B1 Structure
• B2 Durability
• E2 External Moisture
• F2 Hazardous Building Material
• G4 Ventilation
• G7 Natural Light
• H1 Energy Efficiency

Regardless of the project—whether a new build, renovation, or repair—you are responsible for ensuring your work meets these standards, even if the architect or council hasn’t checked for compliance.

Why Become a JMF Manufacturer? In New Zealand, timber joinery is not classified as an “Acceptable Solution” under the Building Code. This means that when timber joinery is specified for a project, you must demonstrate its compliance with all relevant clauses of the Code. There are two ways to do this:

1. As an Alternative Solution
2. Through a Verification Method

With JMF joinery, compliance is straightforward. Our products have been tested to NZS: 4211 standards, a Verification Method that allows you to label your joinery as compliant with the relevant B1 and E2 clauses of the Code. JMF provides the testing data and support services necessary to ensure your products meet the required standards from design to consent stages.

Producing untested joinery means having to prove compliance through an Alternative Solution. This process is far more complex and may not always be accepted by councils or other authorities. You’ll need to demonstrate compliance using one or more of the following methods:

• Your own calculations or tests
• Comparison with acceptable solutions or verification methods
• Trade literature
• Appraisal from a third party
• In-service history
• Other expert evidence

By partnering with JMF, you can avoid these complexities and simplify the process of proving compliance.

What Else JMF Offers:

1. Comprehensive Manuals: We provide detailed manufacturing manuals that cover the full JMF joinery suite, ensuring that all manufacturers follow a consistent and high-quality process.

2. Compliance Tags: As a JMF-affiliated manufacturer, you can purchase compliance tags to attach to your joinery, making it easy to demonstrate that your products meet Building Code requirements. These tags serve as a “green ticket” with the council, showing that your joinery is Code-compliant.

3. Technical Support and Advocacy: JMF offers ongoing technical advice and support, helping you navigate any challenges during the consent process. Whether you’re working with architects or building consent officers, JMF will advocate for you.

4. Tools for Compliance: We provide tools to help you meet compliance standards for other Building Code clauses. Our H1 thermal calculation tool and engineering calculator are designed to simplify your compliance efforts.

5. Commitment to Future Development: JMF is committed to advancing the timber joinery industry in New Zealand. We continuously invest in product development and testing to keep up with legislative changes, ensuring that your products remain compliant with the latest standards.

6. Industry Connection: JMF is owned by Master Joiners, New Zealand’s industry body for joiners. As a JMF manufacturer, you’ll be part of a strong support network, giving you access to resources and representation.
