How to Deal with Condensation in Container Houses

Condensation in container houses is primarily related to temperature differences and humidity, and can be reduced by measures such as improving insulation, controlling humidity, and ensuring airtightness.

Condensation in container houses usually occurs due to significant temperature differences between the interior and exterior, combined with high indoor humidity. For example, in cold winters, activities by occupants generate more moisture, or storing items with high humidity levels increases indoor air humidity. When warm, humid air comes into contact with the colder inner walls of the container house, water vapor condenses into droplets. Additionally, if the container house is not well-sealed, external humid air can easily enter, increasing indoor humidity; a humid surrounding environment also increases the likelihood of condensation.

To reduce condensation in container houses, the following measures can be taken:

• Improve insulation: Enhancing the thermal insulation performance of the container house to minimize temperature differences between the interior and exterior is crucial. For instance, regular cultural tourism space capsules are filled with high-density insulation rock wool and thickened insulation layers, using integral thermal break insulation technology to block temperature conduction between the interior and exterior. Windows and doors are made of thermal break aluminum double-glazed units to prevent heat penetration, effectively reducing temperature differences and the likelihood of condensation.
• Control indoor humidity reasonably: Avoid excessive indoor humidity by ventilating to allow air circulation between the interior and exterior, thereby reducing indoor humidity. Dehumidification equipment, such as dehumidifiers, can also be used to directly remove moisture from indoor air, keeping it dry and reducing condensation.
• Ensure good airtightness: Prevent external humid air from entering the interior. Regular construction methods employ integral waterproof membranes + full sealing with sealant + sloped drainage designs, with板材 (panels) overlapping smoothly without breaks to prevent water penetration. Additionally, strengthening roof waterproofing, corner waterproofing, and edge-sealing waterproofing techniques ensures the airtightness of the container house, reducing the entry of external humid air, lowering indoor humidity, and consequently reducing condensation.
