Insulation Layer of Container Mobile Housing

The insulation layer of container mobile housing can be achieved through various methods, with the core being the selection of appropriate materials, optimization of structural design, and attention to detail.

I. Use of Specialized Insulation Materials Container insulation liners are a new type of composite packaging material originally designed to protect products inside the container from environmental temperature and humidity during transportation. However, they can also be used for temporary insulation in mobile housing. For long-term living scenarios, it is recommended to use professional insulation materials such as expanded polystyrene (EPS), polyurethane foam board (PU), and rock wool board. These materials have low thermal conductivity (usually below 0.035W/(m·K)), effectively blocking heat transfer. Among them, polyurethane foam board has a high closed-cell rate and excellent waterproof performance; rock wool board combines fire resistance and sound absorption functions, making it suitable for scenarios with high safety requirements.

II. Addition of Insulation Layer Structures

1. External Insulation Layer: Install metal or decorative panels on the exterior wall surface of the container, with insulation material filled in between to form an 'external insulation' structure. This method does not occupy indoor space but requires attention to the connection between the waterproof layer and the insulation layer to prevent rainwater infiltration.
2. Internal Insulation Panels: Directly paste or nail insulation panels, such as expanded polystyrene or phenolic panels, onto the interior walls of the container, and then cover them with gypsum board or wood veneer. This method is simple in construction but reduces indoor clear height, requiring prior planning of space layout.

III. Optimization of Door and Window Design Doors and windows are the main channels for heat loss. Double or triple glazing (with inert gas filling in the gaps) should be used, with a heat transfer coefficient as low as 1.8W/(m²·K), saving over 50% more energy than single glazing. Additionally, installing sealing strips at the connection between the window frame and the wall and automatic lifting sealing strips at the bottom of the door can further reduce heat loss caused by air convection.

IV. Key Points in Detail Handling

1. Material Joints: The joints of insulation panels should be sealed with specialized tape or foam sealant to avoid the 'thermal bridge' effect.
2. Connection Parts: Metal components such as container corners and rivets should be wrapped with insulation material to prevent local condensation.
3. Structural Integration: A moisture barrier (such as aluminum foil film) should be installed between the insulation layer and the container steel plate to prevent moisture condensation from affecting insulation performance.

Through the comprehensive application of material selection, structural optimization, and detail control, the insulation performance of container mobile housing can be significantly improved, meeting living needs under different climatic conditions.
