Super-Insulated Container House

The super insulation of container houses mainly relies on four core elements: material selection, structural design, process optimization, and auxiliary equipment:

1. Selection and Application of Insulation Materials

The key to insulation performance lies in the thermal conductivity and thickness of the materials. Mainstream materials include polyurethane foam boards, rock wool boards, and polystyrene foam boards. For example, in the patented technology of Suzhou Tiandi Color Steel, the side panels are internally filled with polyurethane foam plastic, and the support panels are embedded with rock wool. Both have a thermal conductivity lower than 0.03W/(m·K), effectively blocking heat conduction. In addition, Qinghai Guangzan Light Steel has achieved an insulation effect close to that of traditional buildings by thickening the insulation layer. When assembling materials, gaps should be avoided to prevent the "cold bridge effect" from reducing overall performance.

2. Thermal Insulation Optimization in Structural Design

The insulation of container houses needs to be achieved through the synergy of multiple layers. The typical structure includes an outer layer of anti-corrosion color steel plate, an intermediate insulation layer (such as a polyurethane foam layer over 50mm thick), and an inner layer of fire-resistant gypsum board + moisture-proof film. This design meets the requirement in the national "Technical Standard for Steel Structure Integrated Houses" that the heat transfer coefficient of the walls of residential container houses should be ≤0.45W/(㎡·K). For example, a café in Moganshan uses sandwich panels with an aluminum foil reflective layer, combined with adjustable sunshades and bottom ventilation slots. In actual measurements, the cabin's temperature rise in summer is 22 minutes slower than that outdoors, and in winter, the indoor temperature only drops by 1.3℃ after being sealed for 8 hours.

3. Sealing Treatment in Process Details

The splicing process and overall airtightness directly affect the insulation effect. Sealing strips should be installed at the edges of doors and windows, and professional sealing materials should be used to fill the joints between panels to avoid heat leakage. For example, in the temporary construction scenario in Shijiazhuang, Hebei Yaolong Steel Structure Engineering Co., Ltd. has minimized the impact of gaps by optimizing the splicing process and simultaneously sealing the corners to ensure the insulation performance of the overall structure.

4. Supplementary Temperature Control Equipment

Under extreme climatic conditions, equipment such as air conditioners and graphene floor heating can further regulate the indoor temperature. For example, Qinghai Guangzan Light Steel points out that the popularity of air conditioners has significantly improved the living comfort of container houses in summer. In winter, through the combination of insulation materials and temperature control equipment, the effect of "warm in winter and cool in summer" can be achieved.
