A smarter approach to fire-rated ceilings and bulkheads — KOROK® Ceiling & Bulkhead Systems provide a smarter, more efficient approach to fire-rated ceiling construction for commercial, industrial, and infrastructure projects.

Utilising KOROK® 78mm panels, these systems are designed to simplify fire continuity while enabling fast underside installation with Fire Resistance Ratings of up to -/120/120.

Developed to address the practical challenges faced on modern construction sites, KOROK® systems are ideal for service-heavy environments, restricted-access ceiling spaces, and complex construction sequencing. The lightweight panel design helps reduce installation complexity, minimise disruption to other trades, and improve overall site efficiency.

• Simplified Process: Conventional fire-rated ceiling and bulkhead systems can create unnecessary challenges around ceiling plenums, service coordination, access limitations, and installation sequencing. In many cases, traditional systems require additional linings to be installed from above, increasing labour, programme time, and coordination requirements. KOROK® Ceiling & Bulkhead Systems simplify this process.
• Efficient Installation: Designed specifically for installation from the underside, KOROK® systems reduce reliance on roof-space access while supporting efficient programme sequencing for new builds, retrofit projects, and staged construction works.
• Integration: The symmetrical profile of the KOROK® 78mm panel allows seamless integration with KOROK® fire-rated wall systems, concrete/masonry, and structural steel elements. By utilising compatible KOROK® wall and ceiling systems together, fire continuity can be maintained without overcomplicating details or requiring excessive additional ceiling linings.
• Compliant: All KOROK® panel tasting has been carried out at nationally accredited laboratories to AS1530: Part 4, providing designers, engineers, and contractors with confidence in system performance and compliance. Keep it simple with lightweight, code-compliant KOROK® systems designed to work together to meet demanding fire and acoustic performance requirements.
