Container House Fireproof Board

The commonly used fireproof board materials for container houses mainly include rock wool board, fireproof cotton, glass-magnesium board (magnesium oxide board), inorganic fireproof board, etc. Some products adopt Class A fireproof materials to meet fire safety requirements.

1. Rock Wool Board and Fireproof Cotton

Rock wool board and fireproof cotton are widely used fireproof filling materials in container houses. Their core advantage lies in their Class A fireproof performance (meeting fire resistance limits), which complies with fire safety regulations at construction sites. These materials are based on inorganic mineral fibers and have the following characteristics:

• High-temperature resistance: With a melting point exceeding 1000℃, they do not release toxic gases when burning and can effectively block the spread of fire.
• Strong stability: They have low wet expansion and thermal shrinkage rates, making them less prone to deformation or cracking due to environmental changes.
• Sound insulation and thermal insulation: They have a low thermal conductivity coefficient (e.g., 0.216W/(m·k)), and a 6mm-thick board can achieve a sound insulation level of 29dB, providing both energy efficiency and comfort.

2. Glass-Magnesium Board (Magnesium Oxide Board)

Glass-magnesium board is made primarily of magnesium oxide and magnesium chloride, forming a high-strength fireproof structure through chemical reactions. It is commonly used in the wall and floor systems of container houses. Its characteristics include:

• Class A1 non-combustibility: It does not burn at 800℃ and has no flames at 1200℃, complying with the GB8624-2012 standard.
• Waterproof and moisture-proof: It has a low water absorption rate and will not deform or rot due to moisture, making it suitable for rainy environments.
• Environmentally friendly and safe: It does not contain harmful substances such as asbestos or formaldehyde and can be in direct contact with food, posing no harm to humans.
• Easy processing: It can be sawed, nailed, glued, and painted, adapting to various decoration needs.

3. Inorganic Fireproof Board and Ice-Fire Board

Some manufacturers offer inorganic fireproof boards (such as calcium silicate boards) or ice-fire boards (decorative glass-magnesium boards). These materials are processed through special techniques to enhance their aesthetic appeal while maintaining fireproof performance:

• High structural strength: They have a compressive strength of over 12MPa and excellent impact and bending resistance.
• Strong durability: Their strength increases over time, with a service life of several decades, and they can withstand temperatures as low as -40℃.
• Lightweight: They have a surface density of 0.85-1.27g/cm³, reducing building loads and facilitating transportation and installation.

4. Material Selection and Safety Regulations

According to fire safety requirements, container houses should prioritize the use of Class A fireproof materials (such as rock wool and glass-magnesium boards) and avoid using flammable sandwich materials such as polystyrene and polyurethane foam. Additionally, attention should be paid to:

• Electrical safety: Wires should be protected with sleeves, and switch boxes should be installed with metal galvanized surface-mounted fixtures to reduce fire hazards.
• Spacing requirements: Container panels should maintain a safe distance of at least 6 meters to prevent the chain spread of fire.
• Fire extinguishing equipment: Simple fire extinguishing equipment should be equipped both inside and outside to enhance initial fire response capabilities.
