What Are the Disadvantages of Container Houses

The disadvantages of container houses mainly include limited space, poor thermal insulation and sound insulation, safety hazards, low living comfort, and high decoration and maintenance costs:

1. Limited Space
   The interior space of container houses is relatively narrow, especially in terms of height and width. For example, at the Nagoya Asian Games, athletes over two meters tall were unable to stretch their legs straight in bed, and the compact room layout made movement inconvenient. Additionally, ventilation and lighting conditions are poor, and long-term residence may lead to a sense of oppression.

2. Insufficient Thermal Insulation and Sound Insulation Performance
   Metal materials have strong thermal conductivity. Without the installation of thermal insulation materials, container houses are prone to being cold in winter and hot in summer under extreme climates. For example, the thermal insulation performance of low-end products cannot be guaranteed, and high-priced products need to be selected for improvement. At the same time, the metal structure has a significant sound transmission effect, and the sound insulation performance is poor, requiring additional treatment to reduce noise interference.

3. Safety Hazards

   • Fire Risk: Some container houses use flammable materials such as polyurethane and polystyrene to fill the panel cores, which can spread rapidly in case of fire. For example, container house fires have occurred in Hangzhou and Langfang, resulting in property losses and even casualties.
   • Structural Stability: Exposed steel structures are prone to deformation and collapse under high temperatures. In fires, they usually lose their load-bearing capacity within 10 minutes, hindering evacuation and rescue.
   • Narrow Passageways: Some renovated houses do not reserve safety passageways, making it difficult for people to evacuate in case of fire.

4. Low Living Comfort
   Container houses were originally designed for cargo transportation, not for living. In actual use, problems such as narrow beds and room leaks may occur. For example, at the Nagoya Asian Games, the Indian delegation built a "simulation cabin" in advance to adapt to the environment, while the Korean delegation complained about leaks in the washbasin and water accumulation on the floor.

5. High Decoration and Maintenance Costs
   If improvements in thermal insulation, sound insulation, or anti-theft performance are required, additional decoration is needed, increasing costs. For example, although traditional container modifications have good anti-theft effects, they have poor thermal insulation and sound insulation and require secondary interior decoration. In addition, the waterproofing at the joints is poor, requiring regular maintenance, and materials such as oil-based paints may also be harmful to health.
