Is the Southern Container House Cold?

If proper insulation measures are taken, southern container houses will not be very cold in winter; if not, they will be relatively cold. Here is a detailed analysis:

Reasons for being cold without insulation treatment

• Characteristics of metal materials: Most of the exterior surfaces of container houses are made of metal materials, which have low specific heat capacity and high heat transfer efficiency. In winter, the low outside temperature will quickly conduct through the metal shell into the interior, resulting in a relatively low indoor temperature.
• Cold air infiltration through gaps: There may be gaps in the iron sheets. In winter, cold air will blow directly into the interior, further lowering the indoor temperature and making people feel chilly. For example, Mr. Miao's container house before renovation was extremely cold in winter, and he had to wrap himself in a thick down jacket to keep warm inside.

Insulation treatments can improve the cold situation

• Select appropriate insulation materials: Common insulation materials such as polystyrene boards, polyurethane foam boards, and rock wool boards have low thermal conductivity and good thermal insulation properties. They can effectively block heat transfer and improve the thermal insulation performance of the house.
• Add insulation layers: In the design of container houses, adding insulation layers on the exterior wall surface or interior walls, such as external insulation layers and interior insulation boards, can form effective thermal insulation barriers, reduce heat transfer, and maintain a stable indoor temperature.
• Optimize the design of windows and doors: Use double- or triple-glazed windows, which have low thermal conductivity and good thermal insulation properties. Install sealing strips around the edges of windows and doors to effectively reduce heat leakage and improve thermal insulation effects.
• Add temperature control equipment: Install facilities such as air conditioners, entrance air curtains, and graphene floor heating to regulate the indoor temperature. In the south, air conditioners are one of the effective weapons against the cold. They can raise the temperature through thermal convection and also have a dehumidifying effect.
