Juken New Zealand Forests: FSC Certification Split Enhances Transparency and Management

Juken New Zealand Ltd (JNL) has recently undergone a significant change in their Forest Stewardship Council® (FSC®) (FSC® C013648 & FSC® C210401) certification structure. Previously operating under a single FSC Forest Management certificate, JNL has now split this into two separate certificates to improve operational clarity and align more closely with FSC’s updated standards.

The decision to divide the certified management unit reflects JNL’s commitment to sustainable forest management and its responsiveness to evolving regulatory and stakeholder expectations. Each certificate now covers distinct forest management units, allowing for more tailored oversight and reporting. This change enhances transparency and enables more precise environmental and social performance tracking across JNL’s diverse forest holdings.

The split also aligns with the updated FSC Forest Stewardship Standard for New Zealand, which was issued in 2024. This standard emphasises key issues such as protecting waterways, erosion control, and culturally appropriate engagement. By restructuring its certification, JNL is better positioned to meet these rigorous requirements and demonstrate its leadership in responsible forestry.

The dual certification structure is expected to facilitate more effective audits and continuous improvement in forest management practices.

As global demand for sustainably sourced timber grows, JNL’s proactive approach reinforces their reputation as a responsible forest manager and strengthens access to domestic and international markets that prioritise certified wood products.

Both their J-Frame and Triboard products are FSC CoC certified, reinforcing JNL’s commitment to sustainable forestry and responsible sourcing throughout their engineered wood range.

Triboard — TGV Lining

Juken New Zealand

View Product

Triboard TGV is a durable lining for walls and ceilings.

Common sheet sizes: 2400 x 400 x 15mm / 3740 x 400 x 15mm
Suitable for home renovations, sheds, beach houses, garages, and workshops — where high impact resistance is required
Paint-ready. MDF surfaces offer a grade 5+ paint finish capability
Easy to install. The panels are light enough for a one man installation

Tongue and Groove joint:

Each TGV panel is 400mm wide and it may be that the stud centres are not at 400 or, if lining a Portal or Pole shed, it’s likely that there will be no studs at all. Having a Tongue and Groove joint between the Triboard panels means that it doesn’t matter what centres the studs are because no framing is needed behind the join.
Or, in the case of having girts only in a portal building, you don’t need to install vertical nogs to support the edge of the sheet as you would for other lining products.

Triboard TGV as Wall Bracing:

Owing to the narrow (400mm) width of a TGV panel, it is generally not suited to installation as bracing as the fixings required to the bottom plate are prohibitive
Should Wall Bracing be required, full size Triboard sheets are available in 10mm and 15mm. Bracing figures compliant with NZS3604 are available from Juken.

Fixing Triboard TGV Panels to the frame:

When lining Steel Portal Sheds:
- Self-Tapping 8g screws suitable for light gauge steel with Drill or Winged points, fixed into the horizontal girts
- Girts should be at no more than 1.0m spacing vertically
- The screws are recommended at approximately 180mm centres in each panel. (3 per panel per girt)
When lining a Timber Portal or Pole Farm Shed:
- Use 8g CSK wood screws 35-40mm long into the girts
- Install screws to the same fixing pattern as for steel (3 per panel per girt)
- The same fixing is appropriate into the horizontal nogs of conventionally framed timber walls

Panel adhesive is recommended for all fixing types:

As Triboard is not used as wall bracing, and therefore doesn’t perform a structural role, these fixing specifications are simply guidelines
For less visible fixing, good results can also be obtained using gun fired nails or brads in conjunction with panel adhesive.
