Images of Insulation Boards for Container Houses

Currently, images of insulation boards for container houses cannot be provided directly, but their types, structures, and functional characteristics can be described in detail.

Insulation boards for container houses are key materials for enhancing building energy efficiency. Their core function is to maintain stable indoor temperatures by blocking heat conduction, reducing heat convection and radiation. Depending on the materials and processes used, common insulation boards can be classified into the following three categories:

1. Polystyrene Foam Boards (EPS/XPS)
Polystyrene foam boards are among the most commonly used insulation materials for container houses. EPS (Expandable Polystyrene) boards are formed through a foaming process, creating a closed-cell structure with low density, moderate insulation performance, and low cost. XPS (Extruded Polystyrene) boards, on the other hand, are formed through an extrusion process, resulting in a denser closed-cell structure with lower thermal conductivity and higher compressive strength, suitable for scenarios with higher insulation requirements. These boards are often composite with metal panels (such as color-coated steel sheets) to form a "metal-foam-metal" sandwich structure, ensuring both insulation effectiveness and structural strength.

2. Polyurethane Foam Boards (PU)
Polyurethane foam boards are made from isocyanate and polyether polyol as raw materials and applied through on-site spraying or prefabricated board forms. They have a closed-cell rate of over 95%, extremely low thermal conductivity (approximately 0.022-0.028 W/(m·K)), and superior insulation performance compared to polystyrene boards. Additionally, polyurethane foam has strong adhesion to container steel plates, forming a seamless insulation layer that effectively reduces thermal bridging effects. Prefabricated boards are often composite with aluminum foil or glass fiber cloth to enhance fire resistance and weather resistance.

3. Rock Wool/Glass Wool Boards
Rock wool boards are made from basalt as a raw material, melted at high temperatures and then blown into fibers, while glass wool boards are made from glass through a similar process. Both are inorganic fiber materials with Class A non-combustibility, sound absorption and noise reduction, and high-temperature resistance, suitable for container houses with strict fire safety requirements. Rock wool boards have a thermal conductivity of approximately 0.036-0.044 W/(m·K), with slightly lower insulation performance than polystyrene and polyurethane boards but better long-term stability and are environmentally friendly and non-toxic.

Structural and Design Considerations
Insulation boards are typically installed on the inner and outer walls of containers through mechanical fastening or adhesive bonding, with tongue-and-groove or bead sealing between boards to prevent heat loss. Some high-end designs adopt a double-layer insulation structure, filling insulation material between the inner and outer walls to further reduce heat conduction. Additionally, the surface of the boards can be coated with a reflective coating to reduce heat absorption by reflecting solar radiation, enhancing summer insulation effects.
