Are Container Houses Afraid of Sun Exposure?

Container houses are afraid of sun exposure, and long-term sun exposure can have adverse effects on their performance and service life, as detailed below:

Structural and Material Aspects

• Metal materials are prone to damage: The main body of container houses is mostly made of metal materials. Prolonged sun exposure can cause a sharp increase in metal temperature, accelerating the metal oxidation reaction, leading to aging and peeling of the container surface coating, reducing its corrosion resistance, and thus affecting structural strength and stability.
• Panel performance degradation: If container houses use simple panels that are thin and lack insulation layers, sun exposure can cause changes in the internal stress of the panels, leading to issues such as deformation and cracking, and shortening the service life of the panels.

User Experience Aspects

• Indoor temperature soars: Simple container panels lack effective thermal insulation measures. Under summer sun exposure, the indoor temperature can rise significantly, much higher than the outdoor temperature, seriously affecting the comfort of living or working.
• Poor thermal insulation effect: Even after modifications to add thermal insulation layers, such as using polyurethane foam layers, long-term sun exposure can gradually degrade the performance of the thermal insulation materials, reducing the thermal insulation effect and causing the indoor temperature to fluctuate greatly with changes in the outside temperature.

Protective Measures

• Shading during storage: For unused container houses, pay attention to shading during storage to avoid direct sunlight. You can build a sunshade or choose a storage site with shelter.
• Protection during use: For container houses in use, install sunshades or sunshading curtains on the roof to reduce the area of direct sunlight. At the same time, use standard processes for thermal insulation treatment, such as filling the interior with high-density thermal insulation rock wool, combining with thermal break insulation processes, and selecting thermal break aluminum double-glazed windows and doors to improve indoor temperature and enhance user comfort.
