Adding Walls Inside Container Houses

There are multiple methods for adding walls inside container houses, and it is essential to select appropriate material and structural combinations based on actual needs while paying attention to optimizing spatial layout.

I. Common Material and Structural Combinations for Wall Addition

1. Basic Combination One

   • Outer Layer: Metal paint, providing corrosion resistance and decorative functions.
   • Structural Layer: Galvanized corrugated sheets (customizable thickness), serving as the foundation for the wall skeleton, offering both strength and rust resistance.
   • Insulation Layer: Polyurethane foam (optional), filled in the gaps between corrugated sheets to prevent condensation and enhance insulation; this layer can be omitted if insulation requirements are low.
   • Main Insulation Layer: Insulation rock wool, further enhancing thermal insulation performance and reducing energy consumption.
   • Support Layer: Steel studs, constructing the internal framework of the wall to support subsequent decorative materials.
   • Decorative Layer: Bamboo-wood fiber boards or wooden veneers, providing an aesthetically pleasing surface while meeting fire and moisture resistance requirements.

2. Basic Combination Two

   • Outer Layer to Insulation Layer: Same as Combination One (metal paint, galvanized corrugated sheets, polyurethane foam, insulation rock wool).
   • Base Treatment: Fixing plywood or OSB boards onto steel studs as support for the gypsum board base.
   • Surface Treatment: After covering with gypsum board base, applying anti-rust paste locally (for metal connection parts) and finally painting with latex paint to achieve a smooth and durable wall finish.

II. Considerations for Wall Addition Design

1. Space Optimization: The internal width of containers is limited (usually 2.4-3 meters), so wall addition should avoid excessive space occupation. It is recommended to use lightweight partitions (such as glass or perforated panels) to divide functional areas while maintaining a sense of openness.
2. Structural Safety: The load of the wall should be evenly transferred to the container frame through steel studs to avoid local stress concentration. If the wall addition is near doors or windows, strengthen the stud connections to resist wind pressure.
3. Functional Adaptation: Select materials based on the intended use. For example, kitchens and bathrooms require additional waterproof layers (such as cement pressure board base), while bedrooms may focus on sound insulation (adding soundproof cotton).

III. Recommended Construction Process

1. Measure the internal dimensions of the container and draw a wall addition plan, specifying the stud spacing (usually 400-600mm).
2. Install galvanized corrugated sheets and steel studs, ensuring verticality and levelness.
3. Fill insulation materials (such as rock wool) and seal gaps to prevent air leakage.
4. Fix decorative bases (plywood/OSB boards) and facing layers (gypsum boards/bamboo-wood fiber boards), treating joints and corners.
5. Complete surface decoration (latex paint/wood veneer) and inspect the wall for flatness and firmness.

By reasonably selecting materials and structures, wall addition in container houses can balance functionality, aesthetics, and cost-effectiveness, meeting diverse living needs.
