Reasons for Cold Container Houses
The main reasons for the coldness of container houses are their low specific heat capacity and high heat transfer efficiency of metal materials, as well as the inadequate insulation treatment of some houses.

Characteristics of Metal Materials: The outer skins of container houses are mostly made of metal materials. Metals have a relatively low specific heat capacity and high heat transfer efficiency. This means that in cold environments, metals will quickly transfer the external low temperature to the interior, causing the indoor temperature to drop.
Insufficient Insulation Materials: Some container houses do not fully consider insulation needs during the design phase and either do not use insulation materials or only use thin ones. Common insulation materials such as polystyrene boards, polyurethane foam boards, and rock wool boards have low thermal conductivity and good thermal insulation properties. If not used or used improperly, they will not effectively block heat transfer, resulting in cold interiors.
Unreasonable Door and Window Design: Doors and windows are important channels for heat transfer. If the doors and windows of container houses are designed unreasonably, such as using single-pane glass or having poor sealing, it will lead to significant heat leakage and reduce the insulation performance of the house.
Poor Sealing: If the joints, connections, and the interfaces between the insulation layer and the structure of container houses are not properly handled, gaps will appear, leading to heat leakage. Improper handling of these details will seriously affect the insulation effect of the house.
Impact of Extreme Environments: In extremely cold regions, the winter temperatures are extremely low. The insulation systems of ordinary container houses may not be able to withstand such extreme cold, leading to frozen pipes and frost damage to the walls, further exacerbating the coldness indoors.
