How Container Houses Survive Winter

Container houses can achieve warmth during winter through optimizing insulation design, enhancing door and window sealing, and rationally using temperature control equipment.

Optimizing Insulation Design

The outer skin of container houses is mostly made of metal materials with high heat transfer efficiency. Therefore, it is necessary to select appropriate insulation materials, such as polystyrene boards, polyurethane foam boards, and rock wool boards, which have low thermal conductivity and good insulation properties. In the design of container houses, insulation layers can be added to the outer wall surface or interior walls, such as external hanging insulation layers and interior insulation boards, to form an effective insulation barrier, reduce heat transfer, and maintain stable indoor temperatures. For example, in movable prefabricated houses in mountainous areas of Guizhou, using rock wool boards as insulation layers in the middle of walls can make indoor temperatures 8-10℃ higher than outdoor temperatures, making them very suitable as temporary dormitories or office spaces.

Enhancing Door and Window Sealing

Unreasonable window and door designs can lead to heat leakage and reduce the insulation performance of houses. Therefore, when selecting windows and doors, consider using double- or triple-glazed windows, which have low thermal conductivity and good insulation properties. At the same time, sealing strips can be installed along the edges of windows and doors to effectively reduce heat leakage and improve insulation effects.

Rationally Using Temperature Control Equipment

In addition to the aforementioned insulation measures, temperature control equipment can also be added to regulate indoor temperatures. For example, installing air conditioners, entrance air curtains, graphene floor heating, and other facilities to adjust indoor temperatures according to actual needs, ensuring comfortable living conditions. During post-earthquake reconstruction in Linxia, Gansu, relevant departments used container houses with pre-buried water and electricity pipelines and installed sanitary facilities and electrical appliances to provide warm living environments for affected people.
