Simple Container House Thermal Insulation

Thermal insulation for simple container houses can be achieved through the adoption of multi-layer construction, selection of appropriate thermal insulation materials, optimization of door and window designs, and attention to detail handling.

I. Multi-layer Construction

Container house companies in Hohhot generally use a three-layer construction to enhance thermal insulation performance: the outer layer is a 0.6-millimeter-thick galvanized steel plate to resist wind and sand erosion; the middle layer is filled with 80 to 100 millimeters of rock wool as the main insulation layer to block heat conduction; the inner layer uses PVC-coated steel plates to reduce heat radiation. Some companies also add an elevated layer at the bottom of the container to block ground cold bridge conduction, reducing indoor temperature fluctuations by approximately 40% compared to traditional color steel plate houses.

II. Selection of Appropriate Thermal Insulation Materials

1. Rock Wool: With a low thermal conductivity and good thermal insulation properties, rock wool is a commonly used thermal insulation material for container houses.
2. Polyurethane Foam Board: Filled with more than 50mm of polyurethane foam in the middle, it can effectively block heat conduction and improve insulation efficiency.
3. Polystyrene Board: It can also be used for thermal insulation in container houses, but attention should be paid to its fire resistance.

III. Optimization of Door and Window Design

1. Use of Double or Triple Glazing: Reduces thermal conductivity and improves thermal insulation performance.
2. Installation of Sealing Strips: Install sealing strips around the edges of windows and doors to reduce heat leakage.

IV. Attention to Detail Handling

1. Air Tightness Treatment: Pay attention to the air tightness treatment of door and window sealing strips and joints to prevent local condensation.
2. Thermal Insulation Material Splicing: Use appropriate sealing materials at the splices and connections of thermal insulation materials to prevent heat leakage.
3. Integration of Thermal Insulation Layer and Structure: The junction between the thermal insulation layer and the container structure should use professional construction methods and materials to ensure tightness and structural stability.
