Engineered Fire and Acoustic Systems for Industrial and Commercial Spaces

KOROK® Warehouse and Retail Systems are high-performance, non-loadbearing internal wall systems designed to provide secure fire separation and acoustic control in industrial, warehouse, bulk retail, and intertenancy environments.

The system consists of interlocking steel-faced panels with an aerated concrete core, engineered for certified fire resistance, acoustic attenuation, structural reliability, and long-term durability. Panels can be installed vertically or horizontally and are suitable for both single-wall and twin-wall configurations. The systems have been developed in accordance with recognised Australian and New Zealand Standards and are substantiated through BRANZ testing and appraisal (Appraisal No. 559), ensuring verified and compliant performance.

How the System Works

KOROK® panels are roll-formed from zinc-coated steel strips and encapsulate a lightweight aerated concrete core. The interlocking tongue-and-groove profile forms a continuous sealed barrier that enhances both fire integrity and acoustic isolation.

System performance is achieved through the combined effect of panel mass and composite action, the engineered interlocking joint design, and a tested fastening and support methodology. Optional linings and cavity configurations can also be incorporated to meet specific Fire Resistance Rating (FRR) and Sound Transmission Class (STC) requirements.

Systems are non-loadbearing and must be supported by primary structural elements designed in accordance with NZBC structural requirements. Only genuine, tested KOROK® panels and proprietary components guarantee certified system performance. Substituting alternative products may compromise fire and acoustic ratings and cannot be supported or certified.

Engineered Solid Intertenancy Walls for Multilevel Compliance

In apartment and multi-unit developments, intertenancy walls must provide more than separation – they must deliver reliable fire containment, acoustic privacy, and long-term durability. KOROK® Intertenancy Apartment Systems provide high-performance fire- and acoustic-rated protection for non-loadbearing internal walls. Designed for compliance, construction efficiency, and occupant comfort, the system delivers robust solid-wall performance while meeting the requirements of the New Zealand Building Code (NZBC).

Designed for use in:

• Apartment buildings
• Multi-storey residential developments
• Hotels and retirement complexes
• Mixed-use multi-unit projects

With fire ratings available up to -/240/240 and acoustic performance up to STC 76, the system provides flexibility for designers while delivering reliable, tested performance. BRANZ appraised and developed using recognised Australian and New Zealand Standards, KOROK® systems combine solid-wall resilience with construction efficiency.

How the System Works

KOROK® Intertenancy Apartment Systems use roll-formed steel-faced panels filled with aerated concrete to form a solid, high-mass fire and acoustic barrier between occupancies. The panels interlock to form a continuous wall with inherent fire resistance and sound attenuation properties. Unlike lightweight framed plasterboard systems that rely on linings for performance, the KOROK® panel itself is the primary fire barrier.

The aerated concrete core provides substantial mass, improving low-frequency sound attenuation and reducing airborne sound transfer between dwellings. The solid wall configuration also allows services to be run on the intertenancy wall without requiring individual fire-rated penetrations for outlets and switches, as fire resistance is inherent within the panel. Panels may be installed vertically or horizontally and are available in multiple configurations to achieve varying Fire Resistance Ratings (FRR) and Sound Transmission Class (STC) levels.
