Wall Panels for Container Mobile Houses

Common materials used for wall panels in container mobile houses include rock wool, glass wool, or polyurethane sandwich panels, with color-coated steel sheets or metal sheets also used in some scenarios. Here is a detailed explanation:

1. Rock Wool/Glass Wool Sandwich Panels
These are the mainstream choice for wall panels in container mobile houses, with their core advantages being fire resistance and thermal insulation. Both rock wool and glass wool are Class A non-combustible materials that meet building fire safety regulations, making them particularly suitable for scenarios with high safety requirements (such as construction site dormitories and temporary office spaces). Additionally, these materials effectively block heat transfer, reducing the impact of indoor-outdoor temperature differences on energy consumption and enhancing living comfort.

2. Polyurethane Sandwich Panels
Polyurethane sandwich panels combine thermal insulation with structural strength. Their closed-cell structure reduces air convection, further enhancing insulation performance. However, it is important to note that the fire rating of polyurethane must reach Class A. Using Class B or lower-rated materials may pose safety risks, and fire safety inspection reports should be strictly verified.

3. Color-Coated Steel Sheets
Color-coated steel sheets are composed of metal panels and core materials, offering a smooth surface, corrosion resistance, and the ability to meet aesthetic requirements through different colors and textures. Their core materials are typically rock wool or glass wool, but the use of flammable EPS polystyrene foam should be avoided. Color-coated steel sheet wall panels are commonly used in scenarios with high aesthetic requirements (such as scenic area office buildings and commercial temporary structures).

4. Metal Sheets or Calcium Silicate Boards
Metal sheets (such as galvanized steel sheets) offer high strength and weather resistance, making them suitable for humid or corrosive environments. Calcium silicate boards are known for their fire and moisture resistance but have weaker thermal insulation properties, often requiring composite use with other materials. These materials are mostly used for ceilings or auxiliary wall panels rather than as the main structure.

Selection Recommendations:

• Prioritize Class A non-combustible core materials (rock wool, glass wool) to ensure fire safety;
• Balance thermal insulation and cost based on usage scenarios, focusing on polyurethane in northern regions and rock wool in southern regions;
• When customizing, confirm material thickness (typically 50-100mm) and installation techniques to avoid air leakage or water infiltration through gaps.
