Thermal Insulation Container House Drawings
The design of thermal insulation container houses requires comprehensive consideration of structural modification, thermal insulation treatment, space planning, and compliance. The following are the key points:

I. Basic Structure and Modification of Container Houses
Container houses use standard shipping containers as modules. The common specifications are 20-foot (6 meters long) and 40-foot (12 meters long) containers, with load-bearing capacities of 25 tons and 45 tons respectively. During modification, space can be expanded through container combinations (such as splicing and staggered stacking). For example, 2-3 containers can be used to build a single-story residential building of about 100 square meters, including living and dining areas, bedrooms, and bathroom facilities. Staggered design can optimize ventilation and lighting, leaving a courtyard or aisle area on the ground floor. During modification, attention should be paid to the anti-rust treatment of cutting and welding areas. All cut edges should be polished and then coated with epoxy primer and topcoat to prevent rusting in the later stage.
II. Thermal Insulation and Heat Insulation Treatment
Container steel has strong thermal conductivity, so a multi-layer structure is required to improve thermal insulation performance:
- Walls and roofs: Use sandwich insulation panels (such as polyurethane or rock wool) and install an insulation layer on the inner layer. The thermal insulation effect is better than that of red brick walls.
- Doors and windows: Choose triple-glazed windows or double-layer laminated glass to reduce heat conduction. Add skylights or eaves sunshades on the roof to prevent sun exposure in summer.
- Floors: Lay sub-floors, floor coverings, and bottom cotton strips to block moisture penetration.
- Sealing: The areas around doors and windows, container joints, and roof gutters should have the sealant replaced regularly (every 5-7 years) to prevent rainwater leakage.
III. Space Optimization and Functional Design
- Small-apartment adaptation: For spaces of 15-30 square meters, it is recommended to use foldable furniture (such as sofa beds and foldable tables) and integrated cabinets to enhance space flexibility. For example, in one case, through hydraulic deck design, a 30-square-meter container was expanded into a multi-functional residence that can accommodate 7 people.
- Lighting and transparency: Install large floor-to-ceiling windows, glass partitions, or roof skylights to enhance indoor brightness. A container villa in Melbourne uses high-strength glass walls at the front and back, allowing sunlight to penetrate the entire house and creating a natural and integrated living experience.
- Facade beautification: Get rid of the industrial feel and create a villa-like atmosphere by painting, themed spray painting, or covering the facade with glass curtain walls.
IV. Compliance and Construction Process
- Approval requirements: For rural homesteads, construction approval is required, and structural drawings should be provided. Construction on cultivated land and basic farmland is strictly prohibited, and forestry approval is required for forest land. Leased land is only for temporary buildings, and the contract should clearly specify the nature of use.
- Foundation construction: Containers should be elevated above pile foundations to prevent moisture and insects and facilitate site leveling.
- Maintenance cycle: In inland dry areas, anti-corrosion paint should be reapplied every 8-12 years, every 7-10 years in southern humid areas, and every 3-5 years in coastal areas. Weld seams, wall corners, and other areas should be inspected and repainted every year.
