Thermal Insulation of Container Houses
Thermal insulation of container houses can be achieved by selecting high-quality thermal insulation materials, optimizing structural design, enhancing airtightness, equipping heating facilities, and adopting other auxiliary thermal insulation measures.

Select High-Quality Thermal Insulation Materials
For exterior wall insulation, materials such as EPS (expanded polystyrene) boards, rock wool boards, polyurethane boards, silicate wool, or foam polystyrene boards can be chosen. These materials have low thermal conductivity and can effectively prevent heat loss. For example, rock wool boards not only provide thermal insulation but also fire resistance, significantly improving thermal insulation when installed in the middle of walls. When the thickness of polyurethane foam layer exceeds 50mm, it can efficiently block heat conduction. For interior wall insulation, closed-cell insulation methods can be adopted, using materials such as rock wool and expanded perlite boards, or enhancing insulation performance through plastering, clay walls, or wooden board spraying.
Optimize Structural Design
Designing thermal insulation structures at connection points and corners, isolating the installation areas of doors and windows, and filling gaps can reduce indoor temperature loss. For example, adopting a steel structure framework with a composite sandwich panel enclosure system, ensuring that the density and thickness of the sandwich panels meet standards (e.g., thermal conductivity ≤ 0.45W/(㎡·K)), can improve insulation efficiency. Additionally, designing adjustable sunshades and bottom ventilation slots can balance indoor temperatures and avoid extreme temperature differences.
Enhance Airtightness
Ensure that windows and doors are well-sealed by installing draft stoppers or weatherstripping to prevent cold air from entering. For example, installing weatherstripping along window edges can reduce heat leakage. Container houses with poor airtightness are prone to temperature drops due to snow infiltration on snowy days, so regular inspection and maintenance of sealing structures are necessary.
Equip Heating Facilities
Use devices such as electric heaters, air conditioners, or graphene floor heating to raise indoor temperatures. For example, a small electric heater can heat a room within half an hour, and when combined with thermal insulation materials, it can reduce energy consumption. Air conditioners or entrance air curtains can quickly adjust room temperatures, but regular inspection of equipment status is necessary to avoid safety hazards.
Other Auxiliary Thermal Insulation Measures
Laying warm carpets on the floor or reinforcing local areas such as bedsides and walls with thermal insulation boards can further enhance thermal insulation. For example, wooden floors paired with moisture-proof membranes can work together to control temperature and keep the room dry.
