Disadvantages of Mobile Container Houses

The main disadvantages of mobile container houses include inadequate sound and thermal insulation, limited internal space, and potential fire safety hazards, as detailed below:

Inadequate Sound and Thermal Insulation

The sound and thermal insulation performance of mobile container houses is significantly influenced by the materials used. For some low-end products, ensuring effective thermal insulation can be challenging. In cold or hot environments, indoor temperatures are easily affected by external conditions, reducing living comfort. Additionally, since containers are often made of metal, which has good sound transmission properties, their sound insulation performance may also be poor. External noise can easily penetrate indoors, affecting the rest and daily life of occupants.

Limited Internal Space

The internal space of mobile container houses is typically quite narrow. They are primarily designed to meet temporary living or specific functional needs, resulting in relatively compact space utilization. This limited space can be inconvenient for users requiring larger activity areas or storage space. For example, in residential settings, it may not be possible to accommodate multiple occupants simultaneously or place large furniture. In office settings, it may restrict the placement of office equipment and the movement of personnel.

Potential Fire Safety Hazards

• Poor fire resistance and susceptibility to collapse: Most mobile container houses are supported by steel structures. In the event of a fire, temperatures can reach as high as 800-1000℃, while the critical temperature at which steel structures lose their static balance stability is 500℃. Under load, exposed steel structures can quickly deform, causing local damage and leading to the overall collapse of the building. Ordinary container houses typically lose their load-bearing capacity and collapse within about 10 minutes of a fire, posing significant challenges for evacuation and rescue efforts.
• Flammable core materials and rapid spread: To reduce costs, some users purchase container houses with cores filled with flammable materials such as polyurethane and polystyrene. These materials have low ignition points and poor flame resistance, igniting immediately upon exposure to high-temperature sparks, electrical short-circuit sparks, or open flames. Moreover, the honeycomb structure of these materials increases their contact area with air, intensifying combustion and causing fires to spread rapidly.
• Narrow internal passages and obstructed evacuation: Some users, in pursuit of maximizing usable space, fail to provide safety passages and evacuation spaces that meet regulatory requirements, or even occupy evacuation routes with container houses. In the event of a fire, this obstructs evacuation and can easily result in casualties.
