What is the Thickness of Rock Wool Board for Container Houses

The thickness of rock wool boards for container houses typically ranges from 50mm to 150mm, and the specific thickness needs to be determined comprehensively based on climatic conditions, usage, energy-saving standards, and industry norms. Here is a detailed analysis:

1. Climatic conditions are the core influencing factor
In cold regions (such as Northeast China and Northern Europe), priority should be given to meeting insulation requirements. It is recommended that the thickness be between 100mm and 150mm, in line with the thermal resistance requirements specified in the GB/T 11835 - 2016 standard for building insulation in severe cold regions. In temperate regions (such as East China and the central United States), a thickness of 80mm to 100mm is recommended, balancing insulation performance and cost. In hot regions (such as South China and the Middle East), the focus is on blocking external high temperatures, and a thickness of 50mm to 80mm is sufficient to meet the requirements.

2. Usage determines the minimum thickness
For residential purposes, to maintain a comfortable body temperature, the thickness should be at least 100mm. For storage purposes, 80mm is sufficient for storing ordinary goods, while refrigerated containers require a thickness of more than 120mm along with other insulation layers to maintain a low-temperature environment. In addition, standard construction site containers often use 75mm composite rock wool wall panels, which balance insulation and lightweight properties, making them suitable for temporary housing on construction sites.

3. Energy-saving standards provide quantitative references
According to the thermal resistance calculation formula in ISO 6946, the thermal conductivity of rock wool is usually between 0.035 and 0.040W/(m·K). To achieve an R-value of 3.0 (a common residential standard), the thickness should be at least 75mm. This data provides a quantitative reference for insulation performance, preventing excessive energy consumption due to insufficient thickness.

4. Industry-standard thicknesses offer practical guidance
In light-duty insulation scenarios (such as temporary housing), a thickness of 50mm to 80mm is commonly used. For standard insulation scenarios (such as long-term residence), a thickness of 100mm to 120mm is recommended, in line with the guidelines of the European Container House Association (ECBA). In extreme environments (such as polar research stations), a multi-layer composite structure with a thickness of more than 150mm is required to cope with extreme low temperatures. It should be noted that the '600mm' mentioned in some sources may be an error, and it is more reasonable to infer that the range should be 60mm to 150mm based on other content.
