Class B-0 Type C Rock Wool Fireproof Wall Panel

Class B-0 Type C Rock Wool Fireproof Wall Panel

Product Introduction:

The Class B-0 Type C Rock Wool Fireproof Wall Panel is a high-performance, non-combustible composite panel designed for marine and offshore applications requiring intermediate fire protection. Certified to B-0 classification under the IMO FTP Code, this panel provides effective fire resistance while offering superior thermal insulation, acoustic performance, and ease of installation. The "B-0" rating indicates it is a B-class division with zero contribution to fire spread (no continuous flame propagation on the exposed surface), making it an ideal solution for accommodation areas, control rooms, and service corridors on vessels and offshore platforms.

Key Features:

1.B-0 Fire Performance (IMO Certified)

The panel meets the stringent requirements of IMO FTP Code Part 3 for B-class divisions. Key characteristics include:

*Prevents flame passage for the initial 30 minutes of fire exposure (B-15 minimum requirement; B-0 ensures zero surface flame spread)

*Zero continuous flame propagation on the exposed surface during the fire test

*Limits temperature rise on the unexposed side to an average of 140°C (252°F) and a single point maximum of 225°C (437°F) within the first 30 minutes

*Non-combustible core ensures no smoke or toxic gas emission

2.Type C Edge Configuration

Engineered with precision Type C joints (typically a step-lap or tongue-and-groove design) that provide:

*Gap-free, airtight connections between panels

*Quick, tool-efficient installation requiring minimal skilled labour

*Excellent structural integrity under normal marine vibration and thermal movement

*Maintains fire and smoke integrity at all panel junctions

3.High-Density Rock Wool Core

Manufactured from A-class non-combustible rock wool (stone wool) with advanced properties:

*Density: Typically 100–150 kg/m³ (optimised for B-0 performance)

*Melting point exceeding 1000°C (1832°F)

*Zero flame spread and negligible smoke development rating

*Thermal conductivity: ≤ 0.044 W/m·K (excellent insulation)

*Hydrophobic treated to resist moisture, mould, and salt spray

*Sound absorption coefficient (NRC) up to 0.90 – reduces noise from engines, HVAC, and waves

4.Durable Steel Facings

Clad with corrosion-resistant steel facings (0.5–0.6 mm pre-galvanised, stainless, or pre-coated steel) finished in marine-grade paint (e.g., white RAL 9010, light grey RAL 7042, or custom colours). Facings provide:

*Mechanical strength and impact resistance

*Easy cleaning and hygienic surface (ideal for galleys and hospitals)

*Excellent resistance to saline atmospheres and humidity

Typical Applications：

*B-0 class bulkheads in accommodation cabins, lounges, and dining areas

*Fire-rated corridors and escape routes on passenger ferries, cargo ships, and yachts

*Control rooms, switchgear rooms, and radio rooms requiring B-0 protection

*Hospital spaces, galleys, and pantries (where hygiene and fire safety are critical)

*Offshore platform living quarters – intermediate fire zones

*Service shafts, duct enclosures, and stairwells

Advantages for Marine Use：

*Reliable B-0 fire protection – zero flame spread and 30-minute integrity

*Lightweight alternative to steel – reduces vessel deadweight and fuel consumption

*Fast, labour-saving installation – Type C interlocking edges eliminate complex framing

*Vibration resistant – rigid rock wool core dampens shipboard vibrations

*Superior acoustic comfort – reduces noise transmission between cabins and from engine rooms (up to RW 45 dB)

*Thermal insulation – lowers HVAC load and prevents condensation

*Low maintenance – corrosion-resistant facings withstand salty, humid marine environments

*Environmentally friendly – rock wool is made from natural basalt and recycled slag

*Hygienic and easy to clean – smooth steel surface resists mould and bacterial growth
