Drawbacks of Container Houses

The drawbacks of container houses are mainly reflected in poor living experience, safety hazards, weak environmental adaptability, and high long-term usage costs.

Limited living experience: The interior space of container houses is relatively narrow. The length of beds is often less than 195 centimeters, making it difficult for tall people to stretch their bodies. The aisles in the rooms are narrow, and adults can only pass sideways, resulting in cramped overall activity space. In addition, the ventilation and lighting conditions are poor. In some cases, problems such as sink leakage and water accumulation flooding the floor even occur, affecting living comfort.

Prominent safety hazards: Container houses are mainly made of steel structures, which have poor fire resistance. When the fire temperature exceeds 500℃ during a fire, the steel structure is prone to deformation and collapse. Ordinary container houses may lose their load-bearing capacity about 10 minutes after a fire. Some products use flammable materials such as polyurethane and polystyrene to fill the panel cores to reduce costs. These materials have low ignition points and poor flame retardancy. Moreover, the aisles inside the buildings are narrow, making it difficult for people to evacuate in case of a fire. In addition, steel is at risk of rust when exposed to a humid environment for a long time. If professional fire-proof cladding and anti-corrosion treatment are not carried out, it is difficult to ensure the safety of the building throughout its entire life cycle.

Weak environmental adaptability: The thermal insulation performance of container houses is significantly affected by the materials used. Low-end products have difficulty ensuring thermal insulation effects and require additional measures such as thermal insulation cotton and rock wool boards. Their sound insulation performance is also poor, as metal materials have a significant sound transmission effect, requiring additional sound insulation treatment. Under extreme weather conditions, such as in extremely cold regions, if targeted designs (such as avoiding cold bridge effects) are not made, the living suitability may be further reduced.

High long-term usage costs: Container houses have a relatively short service life, usually 10-15 years. As the service life increases, problems such as steel structure deformation and material aging increase, leading to rising maintenance costs. Moreover, their interior area is small, and long-term living can easily cause physical and mental discomfort to occupants, making them unsuitable as long-term living options.
