How Container Houses Survive Winter

Admin September 15, 2026

Container houses can ensure a warm and comfortable living environment in winter by taking insulation measures, optimizing window and door designs, paying attention to detail handling, and adding temperature control equipment. Details are as follows:

I. Select appropriate insulation materials and add insulation layers

Common insulation materials include polystyrene boards, polyurethane foam boards, and rock wool boards. These materials have low thermal conductivity and good insulation performance, effectively blocking heat transfer. During the design of container houses, insulation layers can be added to the exterior wall surfaces or interior walls, such as external insulation layers and internal insulation boards, forming an insulation barrier to reduce heat transfer and maintain stable indoor temperatures. For example, in activity board houses in mountainous areas of Guizhou, using rock wool boards installed between the walls of color-steel houses can make the indoor temperature 8 - 10℃ higher than the outdoor temperature.

II. Optimize the design of windows and doors

Unreasonable designs can lead to heat leakage and reduce insulation performance. Double- or triple-glazed windows should be chosen, which have low thermal conductivity and good insulation properties. At the same time, sealing strips should be installed around the edges of windows and doors to reduce heat leakage and improve insulation effects.

III. Pay attention to detail handling in the insulation system

Details such as the splicing and connection parts of insulation materials and the combination of insulation layers with container structures are crucial. At the splicing and connection points, appropriate sealing materials should be used to prevent heat leakage. At the combination points of insulation layers and container structures, professional construction methods and materials should be employed to ensure tightness and structural stability.

IV. Add temperature control equipment

Facilities such as air conditioners, entrance air curtains, and graphene floor heating can be added to regulate indoor temperatures. In humid southern regions, using color-steel plates with rock wool cores, which have good sealing properties, and adding windbreak strips to windows, along with using a small electric heater at night, can quickly warm up the room within half an hour. Moreover, it doesn't need to be on all day, saving a significant amount of electricity costs.
