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

Selection of Insulation Materials
For exterior wall insulation, materials such as EPS (Expanded Polystyrene) boards, rock wool boards, polyurethane boards, silicate wool, or foam polystyrene boards are commonly chosen due to their excellent insulation properties, effectively preventing heat loss. Interior wall insulation can adopt enclosed insulation methods using materials like rock wool and expanded perlite boards, or through spray-on insulation using materials such as plastering, adobe walls, and wooden boards. For example, the outer layer of a residential container house features anti-corrosion color-coated steel plates that reflect sunlight, the middle layer has a polyurethane foam layer over 50mm thick to block heat conduction, and the inner layer consists of fire-resistant gypsum boards combined with moisture-proof films to jointly control humidity and stabilize temperature. This three-layer structure significantly enhances insulation efficiency.
Optimization of Structural Design
The structural design of container houses is crucial for thermal insulation. Designing insulation structures at connection points and corners, isolating the installation positions of doors and windows, and filling gaps can effectively reduce indoor temperature loss. For instance, adopting a lower rectangular frame combined with central crossbeams and secondary beams for support and reinforcement, while utilizing a double-beam side support structure to support the front and rear outer walls of the house body, can enhance overall stability, prevent deformation or damage caused by excessive local stress, and thereby improve insulation effects.
Enhancement of Airtightness
Ensuring good airtightness of windows and doors is key to preventing cold air from entering the interior. Container houses with poor airtightness are prone to indoor temperature drops in cold weather, and even snowflakes may enter through gaps. Therefore, it is necessary to regularly inspect and replace sealing strips to ensure that doors and windows are tightly closed.
Equipping Heating Facilities
Modern container houses are usually equipped with heating facilities such as electric heaters and air conditioners, which can effectively raise indoor temperatures. However, it is important to conserve energy, avoid waste, and regularly inspect and maintain the equipment to ensure it is in good working condition.
Other Thermal Insulation Measures
Laying warm carpets on the floor and using thermal insulation boards for insulation around bedside positions are also effective methods to improve the thermal insulation of container houses. Additionally, rational utilization of sunshade canopies and bottom ventilation slots can regulate indoor temperature and enhance living comfort.
