Is the Container Renovated House Cold?

After reasonable design and treatment, container-renovated houses can be warm in winter and cool in summer, and are not necessarily cold. The specific reasons are as follows:

Use of thermal insulation materials

Common thermal insulation materials such as polystyrene boards, polyurethane foam boards, and rock wool boards have low thermal conductivity and good thermal insulation properties. In the design of container houses, thermal insulation layers can be added to the exterior wall surfaces or interior walls, such as externally hung insulation layers and interior thermal insulation boards, forming an effective thermal insulation barrier, reducing heat transfer, and maintaining stable indoor temperatures. For example, the outer anti-corrosion color-coated steel plates of residential container houses reflect sunlight, the middle polyurethane foam layer over 50mm blocks heat conduction, and the inner fire-resistant gypsum boards + moisture-proof films work together to control humidity and stabilize temperature. The national 'Technical Standard for Steel Structure Integrated Houses' clearly requires that the heat transfer coefficient of the walls of residential containers should be ≤0.45W/(㎡·K), which is 1.8 times the thermal insulation efficiency of traditional brick-and-concrete walls.

Optimization of window and door designs

Unreasonable window and door designs can lead to heat leakage and reduce the thermal insulation performance of the house. Using double- or triple-glazed windows, which have low thermal conductivity and good thermal insulation properties, can help. At the same time, adding sealing strips to the edges of windows and doors can effectively reduce heat leakage and improve thermal insulation effects.

Detail handling

Issues such as the splicing of thermal insulation materials, the treatment of connection parts, and the integration of the thermal insulation layer with the container structure cannot be ignored. At the splicing and connection points of thermal insulation materials, appropriate sealing materials should be used for sealing to prevent heat leakage. At the junctions of the thermal insulation layer and the container structure, professional construction methods and materials should be used to ensure tightness and structural stability.

Addition of temperature control equipment

Air conditioners, entrance air curtains, graphene floor heating, and other facilities can also be added to regulate indoor temperature and further enhance living comfort.
