Triboard Construction System

The Triboard Construction System is a structural wall and ceiling panel system for use in the construction of Triboard panel houses.  All other aspects of the design and construction of Triboard panel houses such as foundations, floors, roofs, joinery, cladding and interior finishing are conventional.

Triboard wall panels are 36 mm thick, and Triboard ceiling panels are 18 mm thick.  Triboard panels are manufactured to consist of a strandboard core flanked by two outer layers of fibreboard.

Wall and ceiling panels are factory cut to shape and size, including window and door openings, by Triboard remanufacturers. All panel surfaces and exposed edges are pre-painted by the remanufacturer prior to delivery to site. 

On site, the wall panels are connected by specified structural connectors to a ground floor platform of either concrete slab on ground or suspended timber-framed floor. The exterior wall panels are strengthened externally by vertical battens, and the lintels can be strengthened either with a double thickness of Triboard or flitch plates. 

For 2-storey houses, the upper floor construction is of standard timber framing and the upper floor wall panels connected to the floor. 

Ceiling panels are installed over the wall panels and roof trusses are fixed over the ceiling panels. Conventional ceiling systems may also be used. The building is then completed using conventional construction.
