Rock Wool Board Container House

The rock wool board container house is a modular temporary or permanent residential building constructed using rock wool board as the core insulation material combined with a steel structure frame. It has characteristics such as fire resistance, thermal insulation, and environmental protection, and is widely used in areas such as construction site dormitories, office spaces, and emergency housing.

1. Structural and Material Characteristics

Rock wool board container houses typically adopt a three-layer structure:

• Outer Layer: Usually made of galvanized steel sheet or color-coated steel sheet, with a thickness of about 0.6 millimeters, providing resistance to wind and sand and corrosion resistance;
• Middle Layer: Filled with 80-100 millimeter-thick rock wool board as the main insulation layer. It has a low thermal conductivity, effectively blocking heat transfer, and meets Class A fire resistance standards (fire endurance ≥ 1 hour), complying with construction site fire safety requirements;
• Inner Layer: Uses PVC-coated steel sheet or fireproof board to reduce heat radiation and enhance aesthetics.

Rock wool board is made from basalt as a raw material, which is fiberized after high-temperature melting. It has advantages such as non-combustibility, sound absorption, thermal insulation, and corrosion resistance, making it a key material for the thermal insulation and fire protection of container houses.

2. Performance Advantages

• Fire Safety: Rock wool board is a Class A non-combustible material that can effectively delay the spread of fire, meeting public building fire protection regulations;
• Thermal Insulation: In cold regions (such as plateaus and northern areas), rock wool board can reduce indoor heat loss. When combined with sealed designs (such as windbreak strips and double-glazed windows), the indoor-outdoor temperature difference can reach 8-10℃;
• Environmental Protection and Economy: Rock wool board is recyclable, and the main structure of the house has a lifespan of over 20 years. Its modular design supports rapid disassembly and reassembly, allowing for repeated use and reducing long-term costs;
• Strong Adaptability: By adjusting the thickness of the rock wool board or adding auxiliary materials (such as sunrooms and awnings), it can adapt to complex environments such as plateaus, humid areas, and areas with large temperature differences.

3. Application Scenarios and Cases

• Temporary Construction Site Housing: For example, Xi'an Tengdaxing Company provides rock wool board houses with dimensions of 3 meters × 6 meters, priced at 4800-5000 yuan per set, supporting rapid deployment to meet construction period requirements;
• Emergency Rescue Housing: COSCO Shipping uses modular rock wool container houses in plateau areas, integrating functions such as kitchens, storage rooms, and bathrooms, with high space utilization;
• Long-term Residential Spaces: Beijing Yuanhao Company offers rock wool container houses for rent or sale, with a daily rental rate of 6 yuan and a starting sales price of 7000 yuan, equipped with personalized customization services.

4. Usage Precautions

• Fire Protection Regulations: The distance between houses should be ≥ 6 meters to avoid proximity to heat sources and fire sources. Electrical wires and cables should be protected with conduits;
• Maintenance and Upkeep: Regularly inspect the integrity of the rock wool board to prevent moisture absorption or mechanical damage that could reduce thermal insulation performance;
• Approval Procedures: Temporary building permits need to be obtained according to local policies to ensure compliant use.
