Interior Wall Treatment for Container Houses

The interior wall treatment of container houses needs to balance thermal insulation, decoration, and functional optimization. Common methods include thermal insulation material filling, multi-layer structural combination, surface decoration, and construction detail handling. Details are as follows:

1. Thermal Insulation Material Filling
Closed-cell thermal insulation methods are employed, achieving heat insulation through material filling or coating. Common materials include rock wool and expanded perlite boards, or through processes such as plastering and wooden board spraying with polystyrene granule mortar. For example, expanded perlite boards are lightweight and have good sound-absorbing properties, suitable for scenarios requiring sound insulation. The camp of the Santa Cruz Hydroelectric Power Station project in Argentina used 50mm-thick rock wool boards for interior wall filling, combined with 100mm-thick polyurethane boards for exterior walls, achieving efficient thermal insulation. During construction, attention should be paid to the adhesion between the material and the wall to avoid gaps affecting thermal insulation performance.

2. Multi-Layer Structural Combination
The performance of interior walls is enhanced through layered design, with two common approaches:

• Approach One (from outside to inside): Metal paint → Galvanized corrugated board → Polyurethane foam agent (to prevent condensation water) → Thermal insulation rock wool → Steel studs → Bamboo-wood fiber board (or wooden veneer). This structure balances rust prevention, thermal insulation, and decoration, suitable for scenarios with high aesthetic requirements.
• Approach Two (from outside to inside): Metal paint → Galvanized corrugated board → Polyurethane foam agent → Thermal insulation rock wool → Steel studs → Woodworking board/OSB board base layer → Gypsum board base layer → Latex paint. This approach enhances wall flatness through multiple base layers, suitable for scenarios requiring painting or wallpapering.
  Both approaches require ensuring tight connections between layers to prevent cracking due to thermal expansion and contraction.

3. Surface Decoration and Functional Optimization

• Coatings and Decoration: After cleaning and sanding the walls, environmentally friendly coatings with various colors can be chosen, or fun can be enhanced through stickers or wallpapers. Structural parts (such as screws) can be hidden with colored covers or outer packaging to enhance overall aesthetics.
• Storage and Zoning: Utilize storage racks such as wardrobes and bookcases to achieve spatial zoning and improve living experience. For example, setting up an embedded bookcase at the junction of the bedroom and living room saves space and enhances functionality.
• Artistic Embellishment: Hang artworks or small ornaments to highlight personalized characteristics. For example, install adjustable shelves on the wall to display green plants or decorations, adding vitality to the space.

4. Construction Precautions

• Sealing Treatment: Use aluminum alloy pressing strips to fix or inject silicone sealant at the joints between door and window frames and the wall. Stick 3-5mm-thick sealing strips around the windows to prevent cold air infiltration.
• Steel Plate Joint Treatment: The joints of container steel plates need to be sanded flat, painted with anti-rust paint, and then pasted with 50mm-thick polyurethane foam boards to prevent rust from affecting the lifespan of the thermal insulation layer.
• Moisture Prevention and Maintenance: Install waterproof membranes or apply waterproof coatings on the outer side of the thermal insulation layer. Regularly inspect the thermal insulation layer for cracks or peeling and promptly repair it to maintain performance.
