Factory-built wall assemblies introduced alongside trusses and frames.
Melbourne-based Inotek Timber Systems has introduced Pro9 Vic, bringing the Pro9 prefabricated wall system into the Victorian market. (main image: Pro9’s modular walling system used on an AV Jennings build.)
The system sits alongside Inotek’s existing supply of timber trusses, wall frames and panelised components, produced from its Melbourne facility and supplied across metropolitan and regional projects.

Extending beyond component supply
Inotek is now operating from a 10,500 square metre facility in Melbourne’s west, consolidating both its existing timber systems and the Pro9 walling platform within a single production environment.
Its core offering has focused on component-based supply, including trusses, frames, floor systems and prefabricated timber elements. These are typically integrated into conventional construction workflows, with assembly and finishing carried out on site.
The addition of Pro9 Vic introduces a different type of product into that mix. Instead of supplying individual components to be built up on site, the system provides a completed wall assembly delivered as a single unit.
That changes how wall construction is sequenced. Activities such as framing, insulation and external boarding are undertaken offsite, with installation on site focused on placement and fixing rather than assembly. In practical terms, the wall arrives largely resolved, rather than assembled progressively in the open.
The integration of Pro9 panels with Inotek’s existing systems allows for a consolidated ‘whole of house’ delivery model, with . Inotek indicates that, under typical conditions, projects can reach lock-up within approximately five days, with external wall render applied and windows installed in factory, prior to arriving onsite.
What is a Pro9 panel
The Pro9 walling system was developed by Pro9, an Australian company established in 2014.
A Pro9 panel is a load-bearing structural wall comprising a galvanised steel frame, an insulated core and an external board layer. Panels are manufactured offsite and delivered ready for installation, reducing the number of trades required during the framing stage.
Performance is a key characteristic of the system. Reported outcomes include seven-star energy performance with single glazing and higher with double glazing, supported by an R-value of 4.6 and an overall wall thickness of approximately 125mm.
The system has previously been used in Australian residential projects, including collaborations with volume builders such as AV Jennings, where it has been applied in modular housing programmes targeting reduced build durations and improved energy outcomes.
With Pro9 Vic now available through Inotek, the system enters a Victorian market where builders are increasingly incorporating prefabricated elements, particularly where programme certainty and site labour constraints are shaping how projects are sequenced and delivered.
