For lift shafts, stair spline walls and duct walls, KOROK® offers significant advantages over traditional construction.

As it can be installed from one side only, there is no requirement to construct scaffolding inside the shaft, greatly reducing construction time and costs.

Unlike traditional systems, KOROK® can be installed before the structure is watertight and also helps prevent water from entering the building through open shafts.




Please contact us for any technical support or information you require.  We're happy to help.

KOROK Technical Installation Manual COVER

The KOROK® Lift Shafts, Stairs and Ducts Systems only require a small footprint, but provide superior acoustics and exceptional security.

Being impact resistant means that multiple trades can work in the same area without concern, with the panels taking multiple knocks without damage. No timber framing or plasterboard required.

KOROK® Lift Shafts, Stairs and Ducts Systems are favoured over other solutions as they can be pressurised and include multiple self-supporting walls within open cores.
