Container House Insulation Layer
The key points of the insulation layer for container houses include material selection, structural design, process treatment, and performance evaluation dimensions:
Material Selection: Common insulation materials include polystyrene boards, polyurethane foam boards, and rock wool boards. These materials have low thermal conductivity and can effectively block heat transfer. For example, packing-box container houses use hot-dip galvanized cold-formed steel frames paired with fire-resistant polyurethane sandwich panels, providing both insulation and fire resistance. Residential container houses use over 50mm of polyurethane foam layers in the middle to block heat conduction, with inner layers of fire-resistant gypsum boards and moisture-proof membranes working together to control humidity and temperature.
Structural Design: Proper structural design is crucial for insulation. The outer layer of residential container houses uses anti-corrosion color-coated steel plates to reflect sunlight, the middle insulation layer blocks heat conduction, and the inner layer helps control humidity and temperature, forming an effective thermal barrier. Additionally, using 2-3 containers for splicing or staggered stacking can expand functional areas, improve ventilation and lighting, and also benefit insulation. For small units, multifunctional furniture like folding beds and tables can enhance space flexibility.
Process Treatment: Optimizing processes during manufacturing and installation can effectively improve insulation performance. Excellent sealing techniques should be used at panel joints to prevent cold bridge effects; doors and windows should use thermal break aluminum double-glazed units with sealing strips added to the edges; roof and corner closures should be paired with waterproof membranes and fully sealed with sealant, with proper drainage slopes designed and panels overlapped in the direction of water flow to ensure seamless sealing.
Performance Evaluation Dimensions: From the perspective of the material properties of the enclosure structure, the density and thickness of sandwich panels determine insulation effectiveness, with lower thermal conductivity indicating stronger insulation capacity. Jointing techniques affect overall insulation performance, with excellent sealing techniques reducing the impact of gaps. The airtightness of the overall structure is also crucial, with the fit between doors, windows, and frames, as well as sealing treatments at corners, all affecting insulation performance.
