In the thermal insulation design of the maintenance structure of the container mobile room, the local climate conditions, the structural characteristics of the container mobile room, the multimodal transportation conditions and the economic requirements should be considered. The insulation form (i.e. external insulation or internal insulation) should be considered, and the insulation structure and thickness should be ensured through the calculation of small total thermal resistance. In hot summer and cold winter area, it is necessary to consider not only the thermal insulation of the external protective structure of the building, but also the insulation of the external protective structure of the building in winter.

因多式联运过程中的起吊、堆码、栓固等要求，以及港口、堆场作业条件和海陆运输环境、集装箱活动房围护结构通常采用内保温形式。

Due to the requirements of lifting, stacking and fastening in the process of multimodal transportation, as well as the working conditions of ports and storage yards, the sea and land transportation environment, and the enclosure structure of container mobile room, the internal thermal insulation form is usually adopted.

尽可能采用热导系数小保温隔热材料，以减少保温层的厚度，提高室内使用面积。

Thermal insulation materials with small thermal conductivity should be used as far as possible to reduce the thickness of thermal insulation layer and improve the indoor use area.

保温隔热材料按材质可分为无机保温隔热材料、保温隔热材料和金属绝热材料三大类；按形态又可分为纤维状保温隔热材料、多孔（微孔、气泡）状保温隔热材料、层状保温隔热材料等几种。

Thermal insulation materials can be divided into inorganic thermal insulation materials, thermal insulation materials and metal thermal insulation materials according to the materials; according to the form, they can be divided into fibrous thermal insulation materials, porous (microporous, bubble) thermal insulation materials, layered thermal insulation materials and so on.

保温隔热材料的性能取决于材料的热导系数，热导系数愈小，集装箱活动房保温隔热的性能则愈好。保温隔热材料的热导系数与其成分、表观密度、内部结构以及传热时的平均温度和材料的含水率有关。

The performance of thermal insulation material depends on the thermal conductivity of the material. The smaller the thermal conductivity coefficient is, the better the thermal insulation performance of container mobile room is. The thermal conductivity of thermal insulation materials is related to its composition, apparent density, internal structure, average temperature during heat transfer and moisture content of materials.

在集装箱活动房建筑围护结构中常用的绝热保温材料有模塑聚苯乙烯泡沫塑料、挤塑聚苯乙烯泡沫塑料、硬质聚氨酯泡沫塑料、岩棉板、玻璃棉等。

Thermal insulation materials commonly used in containerized building envelope include molded polystyrene foam, extruded polystyrene foam, rigid polyurethane foam, rock wool board, glass wool, etc.
