Design of Container House Roof

The design of a container house roof requires comprehensive consideration of structural stability, climate adaptability, functional requirements, and aesthetics. Common design types include flat roofs, curved roofs, arch roofs, and triangular roofs. Material selection focuses on waterproofing, thermal insulation, and durability, and the supporting structure needs to match the load-bearing capacity of the container. Special designs can integrate functions such as photovoltaic power generation.

Roof Types and Design Points

• Flat Roof Design: Suitable for areas with dry climates and low rainfall, it is simple to construct and has relatively low costs. Waterproofing can be ensured by laying waterproof membranes or applying waterproof coatings. If thermal insulation is required, high-density polyurethane and other insulation layers can be added. For example, some container houses directly lay solar panels on flat roofs to achieve power generation functions.
• Curved Roof Design: Such as Apple Pod container houses, they have a rounded appearance and high internal space utilization. The use of metal integrated wall panels combined with curved roofs not only enhances aesthetics but also strengthens structural stability. The curved roof design helps rainwater naturally slide off, reducing water accumulation and improving waterproofing performance.
• Arch Roof: When constructing an arch roof on two containers, precise measurement of container dimensions, spacing, and positional relationships is required. High-strength materials such as steel or aluminum alloy should be selected. A reasonable steel frame or aluminum alloy support structure should be designed as the supporting structure, bent and installed according to the roof's curvature to ensure a flat and stable roof. Attention should also be paid to the sealing at the connection between the roof and the containers.
• Triangular Roof: Commonly seen in tropical regions, such as some container buildings in Thailand. The top metal sheet provides thermal insulation and rain protection, the middle translucent part allows natural light to penetrate, and the lower steel plate shutters can block rainwater and strong light while maintaining ventilation and preventing heat accumulation in the room.

Material Selection

• Waterproof Materials: Common ones include waterproof fabrics and metal sheets (such as galvanized steel sheets and aluminum alloy sheets). Waterproof fabrics are low-cost and easy to install but have relatively poor durability; metal sheets have high strength and good durability, effectively preventing rainwater penetration.
• Thermal Insulation Materials: High-density polyurethane, rock wool, and glass wool are commonly used thermal insulation materials. For example, Apple Pod container houses spray high-density polyurethane insulation layers throughout the house, combined with a dual heating system of underfloor heating and air conditioning and heat pump auxiliary heating technology to achieve ultra-low energy consumption building standards.
• Roof Covering Materials: In addition to the above waterproof and thermal insulation materials, photovoltaic modules can also be selected according to needs. Some solutions directly embed customized crystalline silicon photovoltaic modules into the roof of the container, integrating the building envelope structure and the power generation structure into one.
