When Fire Safety Meets Real-World Construction Challenges
Butt joints – where two panels meet end-to-end. KOROK® provides an engineered approach so your wall performs as designed across 51 mm (60-minute) and 78 mm (120-minute) KOROK panel systems.
Typical on-site scenarios: panels ordered too short, using leftover stock, restricted site access limiting panel length, or panel cuts needed for complex installations.
Applications
- Single-panel butt joint
- Double-panel butt joint
Methods (Butt Joints)
- Profiled cover / steel flat plate – one or both sides, as detailed.
- Back-to-back C-tracks – protected and unprotected variants.
Plugging Circular Holes (≤ Ø160 mm)
For small circular openings created during installation, repairs, or services, use KOROK-tested plug details to maintain system performance.
Methods
- Fire-rated batt plug + steel flat plate
- Fire-rated batt plug + fire-rated batt cover
