Yes. JSC offers CodeMark-certified timber cladding systems - including VertiClad, RustiClad, BevelClad, and Board & Batten - each with complete installation specifications and technical details. Our CodeMark certification provides formal evidence of compliance with the New Zealand Building Code, including E2 requirements for weathertightness. All technical documentation, drawings, and system guides are available from our Technical Downloads section to assist architects, designers, and builders in meeting consent and compliance requirements.

Please note that while junction details with brick cladding are not specifically part of our CodeMark certified details, based on our experience with timber cladding, we recommend the following approaches:

• Ensure that timber weatherboards are not in direct contact with the brick cladding. Use appropriate flashing (such as a J-mould) to prevent contact and provide a weathertight junction.
• The cavities for both cladding systems must be fully isolated, preventing any airflow between the two cavities.
• Maintain a minimum 10mm gap between the timber cladding and brick to allow for differential movement between the different materials.
• For vertical cladding meeting brick, use a J-mould flashing to create a clean edge and ensure water is directed away from the junction.
• Apply a compatible sealant between the flashing and the timber cladding. Bostik MS Safe Seal and Bostik Seal N Flex Façade are compatible with JSC Scumble and JSC Coda coating systems.

For more detail, contact JSC Technical Support here. As a friendly reminder, while JSC may offer comments and suggestions on the development of specific details for your consideration, we are unable to comment on compliance if the detail falls outside our CodeMark scope. It is the responsibility of the architect/designer to ensure that the details are appropriate for the intended application and compliant with the New Zealand Building Code (NZBC).

Our cladding systems are covered by our CodeMark Certification, the most current version which is available via our Technical Resources area. Upon reviewing this, if you have any queries, please send a detailed enquiry here or contact your local JSC representative.

Our cladding systems' certification and scope of limitations (including applicable timber species) are documented in our CodeMark certificates, all of which are available under Technical Resources. Upon review of these details, if you have any queries, please contact us.

JSC’s timber cladding systems, including RustiClad, VertiClad, BevelClad, and Board & Batten, hold CodeMark certification, giving assurance of compliance in all New Zealand wind and seismic zones when installed as per our specifications. JSC CodeMark-certified cladding systems have a minimum durability of 15 years when installed and maintained in accordance with our specifications. Actual lifespan will depend on the timber species selected, site conditions, coating systems, and maintenance. Species with high dimensional stability, such as thermally modified timber, Western Red Cedar, and Alaskan Yellow Cedar are recommended for projects in exposed environments. Correct installation, coatings, and regular maintenance help ensure ongoing performance. For specific detailing and compliance information, refer to our Technical Documents & Installation Guides or speak with our team for project-specific recommendations. 

JSC timber cladding systems are designed for installation over either 20 mm non-structural or 45 mm structural castellated H3.2-treated cavity battens, as per our CodeMark-certified systems. Installation requirements, including cavity batten layout, flashing and fixing specifications are provided in the relevant JSC Installation and Specification Guides and Technical Drawings for each cladding system.

Please refer to the appropriate system documentation, available at https://jsc.co.nz/downloads, and follow these details in full to maintain compliance and warranty coverage.
