Ship interior partition panels are fire-rated composite sandwich panel systems engineered for B-class and C-class bulkhead divisions in ship accommodation spaces, cabins, and corridors. The outer skins use galvanized steel sheet at 0.5-0.6mm thickness bonded to non-combustible mineral wool cores, meeting the material non-combustibility criteria of IMO FTP Code Annex 1 Part 1.
The mineral wool core delivers acoustic insulation and fire resistance aligned with the 2010 FTP Code and SOLAS Chapter II-2 requirements. B-15 class bulkheads maintain structural integrity and prevent flame passage for 15 minutes, while critical heat flux at extinguishment reaches 20.0 kW/m² or higher per FTP Code Part 5 surface testing for bulkhead linings.
Standard panel thicknesses range from 30mm to 100mm, with widths of 1000mm or 1200mm and custom lengths up to 3,000mm to match ship module dimensions. Joints use cam-lock or tongue-and-groove profiles sealed with fire-rated adhesives, ensuring continuous structural integrity where connecting joints are heavily tested to confirm no flames pass through cracks during the full fire test duration.
These partition panels serve cruise ship cabins, ferry accommodation blocks, offshore platform living quarters, naval vessel compartments, and yacht interior bulkheads. They meet A-class, B-class, and C-class division requirements under SOLAS Chapter II-2 Regulation 5, 6, and 9, providing certified fire containment and acoustic comfort for passenger and crew spaces.

Ship Interior Partition Panel Buying Guide & FAQ
Selecting the right ship interior partition panel requires understanding fire classification, acoustic performance, joint integrity, and regulatory compliance. This guide answers the most common questions from shipyards, naval architects, and offshore module suppliers evaluating fire-rated composite panels for SOLAS-regulated accommodation spaces.
1. What is the difference between A-class, B-class, and C-class divisions?
A-class divisions are steel or equivalent bulkheads that stop smoke and flame for 60 minutes (A-60), used between machinery spaces and accommodation. B-class divisions are non-combustible panels providing 15 to 30 minutes of structural integrity, used for cabin partitions and corridor bulkheads. C-class divisions are non-combustible panels for low-risk internal separations with no specific fire endurance rating.
2. How is the B-15 fire rating tested and verified?
B-15 panels undergo standard fire testing per the 2010 FTP Code, where the bulkhead must prevent flame passage for 15 minutes while maintaining structural integrity. Connecting joints are heavily tested to confirm no flames pass through cracks. Bulkhead linings must achieve critical heat flux at extinguishment of 20.0 kW/m² or higher under FTP Code Part 5 radiant heat exposure testing.
3. Why is non-combustibility critical for ship interior panels?
Per SOLAS Chapter II-2, materials used in ship accommodation spaces must meet non-combustibility criteria tested under IMO FTP Code Annex 1 Part 1. Mineral wool cores and galvanized steel skins achieve this classification, ensuring the panels do not contribute fuel to a fire. Adhesives used in panel construction may use low flame spread characteristics under Part 5 rather than full non-combustibility criteria.
4. What acoustic insulation performance is required?
Ship interior partition panels provide acoustic insulation aligned with IMO Resolution MSC.337(91), which defines sound insulation requirements for cabin and corridor bulkheads in accommodation spaces. The mineral wool core absorbs airborne sound transmission between compartments, supporting passenger comfort on cruise ships and crew rest in offshore living quarters during continuous machinery operation.
5. How are partition panels installed on board ships?
Panels use cam-lock or tongue-and-groove joint profiles sealed with fire-rated adhesives during assembly, ensuring continuous structural integrity at every connection. Joints are designed for efficient shipyard workflow with standard tooling, allowing rapid installation within cabin modules. Penetrations for electrical outlets, ventilation, and piping require certified fire-stopping materials to maintain the division fire rating.
