A Builder's Experience with Triboard TGV: Strength and Efficiency for New Zealand's Earthquake-Prone Areas

Opting for a plasterboard-free build, Tim chose Triboard TGV due to its superior durability, which is essential for homes in quake-prone regions. Paired with SIP panels and a concrete thermal mass bracing wall, Triboard TGV ensured that his house could withstand the challenges of its environment while also providing a refined, clean look.

"The decision was simple," Tim says. "Triboard TGV stood out for its appearance and durability. Other products would have required more dwangs and back blocking, but Triboard saved time and money." All offcuts were used under doors, windows and bulkheads, leaving minimal waste.

With its tongue-and-groove system, Triboard TGV's lightweight panels allow for a one-person installation, significantly speeding up the project.

Tim's attention to detail extended to the aesthetics, as he mitred and glued external corners for a seamless finish. The slightly routed edges gave the walls a soft yet robust appearance, and the TGV grooves aligned perfectly with ply linings where possible. Gluing and secret nailing through the tongue removes the need for filling and sanding of holes, also sped up the process.

Tim originally built an elevated bed platform in his son's bedroom, but as his son grew, he modified the bed to a lower height. This made minor screw hole damage repairs to the Triboard easy, compared to plasterboard, where adjustments would have been a major hassle.

Finishing the project was equally efficient, as Tim required no plastering. As Triboard TGV has a 5+ finish ready for paint, Tim primed both sides before installation, spraying two top coats on the facing side and sanding in between coats. The result was a home that stands strong and looks exceptional, proving that Triboard TGV is the go-to solution for builders looking for both form and function.

Triboard — TGV Lining

Juken New Zealand

View Product

Triboard TGV is a durable lining for walls and ceilings.

FSC Certified

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.
