Container House Insulation Layer Images

Currently, images of container house insulation layers cannot be directly provided, but their common types and structural features can be introduced in detail. The insulation layer of a container house is a crucial structure for enhancing its living comfort, primarily reducing heat transfer through physical barriers or reflection principles. The common types and features are as follows:

1. Expanded Polystyrene (EPS)/Extruded Polystyrene (XPS) Foam Boards
These are among the most commonly used insulation materials for container houses, made from polystyrene resin through a foaming process. Their core advantages lie in low cost and easy installation: EPS (Expandable Polystyrene) has a lower density and is budget-friendly, suitable for projects with limited funds; XPS (Extruded Polystyrene), formed through a continuous extrusion process, has a closed-cell structure, offering higher compressive strength and superior waterproofing, often used for floor or roof insulation. During installation, the foam boards can be directly pasted or fixed to the inner walls of the container, with a fireproof board or decorative panel covering the outer layer, forming a composite structure of 'insulation layer + protective layer'.

2. Rock Wool Boards
Rock wool is made from natural ores like basalt, melted at high temperatures and then blown into fibrous form, pressed into shape with a binder. Its core characteristics are Class A fire resistance and efficient sound absorption: rock wool has a melting point exceeding 1000℃, effectively flame-retardant, meeting building fire safety regulations; its fibrous structure absorbs sound waves, reducing indoor noise. In container houses, rock wool boards are typically used for wall or roof insulation, requiring a waterproof membrane to prevent an increase in thermal conductivity due to moisture absorption. During installation, attention should be paid to sealing to avoid thermal bridging caused by gaps.

3. Polyurethane Spray
Polyurethane rigid foam forms a continuous, seamless insulation layer through on-site spraying, directly adhering to the inner walls of the container. Its advantages include high adaptability and sealing: spraying can cover complex structures (such as pipes, corners), forming an integral insulation layer and reducing heat loss; its closed-cell structure results in a thermal conductivity as low as 0.022W/(m·K), outperforming most boards in insulation. Additionally, the polyurethane spray layer can double as a waterproofing function, suitable for humid environments. However, attention should be paid to the construction environment temperature (usually above 5℃) and subsequent maintenance to avoid UV aging.

4. Aluminum Foil Reflective Film
Aluminum foil reflective film achieves insulation by reflecting thermal radiation, often used in combination with other materials. Its core function is to block radiative heat transfer: in summer, aluminum foil can reflect over 80% of solar radiant heat, lowering indoor temperatures; in winter, it reduces heat radiation from the interior to the exterior. In practical applications, the aluminum foil film is usually laid on the outer side of the insulation layer (such as the surface of foam boards) or combined with an air layer to form a composite structure of 'reflective film + air gap', further enhancing insulation effects.
