How Thick Are the Walls of a Container House

The wall thickness of a container house is typically 75mm. Taking the color-steel glass wool sandwich panel as an example, its structure consists of two layers of 0.45mm-thick color-steel plates on the inside and outside, with 75mm-thick glass wool in the middle. Here is a detailed explanation:

1. Typical Structure and Materials The walls of a packed container house use a 75mm-thick color-steel glass wool sandwich panel. Both the inner and outer layers are 0.45mm-thick galvanized color-steel plates, with glass wool filled in between. This structure takes into account strength, thermal insulation, and fire resistance. The thickness of the glass wool directly affects the heat insulation effect, while the thickness of the color-steel plates determines the wall's impact resistance and durability.

2. Thickness Differences in Different Scenarios

• Standard Packed Containers: A 75mm wall is the mainstream configuration, suitable for temporary or semi-permanent scenarios such as construction site dormitories and office areas.
• Customized Requirements: Some projects may adjust the thickness according to the usage scenario. For example, in extremely cold regions, the thickness of the insulation layer may be increased to 100mm, while lightweight guard posts may use 50mm rock wool panels to reduce costs.
• Repurposed Shipping Containers: If a used shipping container is directly repurposed, its original side panel thickness is 1.6mm (top panel 2.0mm). However, an insulation layer (such as 50mm polyurethane foam) is usually added during the repurposing process to form a composite wall.

3. Key Factors in Thickness Selection

• Thermal Insulation Needs: In northern regions or low-temperature winter scenarios, a thicker insulation layer is required (such as 75mm glass wool plus additional linings).
• Load-Bearing and Stability: For multi-story stacking or long-term use scenarios, it is necessary to ensure the structural strength of the walls. A 75mm sandwich panel can meet most requirements.
• Cost and Transportation: Thicker walls mean higher material costs and transportation weight, requiring a balance between performance and economy.

4. Industry Standards and References According to documents such as the Detailed Explanation of the Specifications and Dimensions of Packed Container Houses, a 75mm wall thickness is an industry-wide standard. However, suppliers may have a ±5mm variation due to differences in craftsmanship or materials. When customizing, it is necessary to clearly state the requirements and ask the manufacturer to provide material test reports (such as fire rating and thermal insulation coefficient).
