Container House Insulation Treatment
Insulation treatment for container houses can be achieved through material selection, structural design, and construction process optimization, with core methods including filling with high-efficiency insulation materials, adopting thermal-break insulation structures, optimizing door and window sealing, and adding temperature control equipment.
1. Insulation Material Selection and Filling
The key to the insulation performance of container houses lies in the insulation layer materials for walls, roofs, and floors. High-density insulation rock wool is a commonly used material with low thermal conductivity, effectively blocking heat transfer. When paired with a polyurethane foam layer, the insulation effect can be further enhanced. For example, residential container houses adopt a three-layer structure of "outer corrosion-resistant color-coated steel plate + intermediate polyurethane foam layer of over 50mm + inner fire-resistant gypsum board", with a wall heat transfer coefficient of ≤0.45W/(㎡·K) and an insulation efficiency 1.8 times that of traditional brick-concrete walls. Additionally, polystyrene foam boards can also be used for internal filling to improve thermal insulation performance by increasing thickness.
2. Application of Thermal-Break Insulation Process
Metal containers have high thermal conductivity and require thermal-break designs to reduce thermal bridge effects. Thermal-break aluminum doors and windows paired with double or triple glazing can significantly reduce heat conduction; walls adopt thermal-break insulation keels, embedding non-conductive materials (such as nylon thermal-break strips) between metal frames to block direct heat transfer. For example, cultural tourism space capsule shops achieve indoor temperatures 5-8℃ lower than outdoors in summer and over 30% improved insulation in winter through thermal-break insulation processes and high-density rock wool filling.
3. Door, Window, and Joint Sealing Treatment
Doors and windows are the main channels for heat loss and require double-glazed units with sealing strips, with edges sealed using silicone or ethylene propylene diene monomer rubber to reduce air infiltration. Panel joints and roof splices require waterproof membranes + full sealing with sealant, with a reasonable drainage slope (e.g., ≥2%) designed to ensure water runs off without leakage. In rainy southern regions, roof waterproofing needs to be reinforced, such as by using TPO waterproof membranes or increasing the thickness of waterproof coatings.
4. Temperature Control Equipment and Auxiliary Measures
Under extreme climate conditions, it is necessary to combine equipment such as air conditioners, graphene floor heating, or air curtains to regulate indoor temperature. For example, Qinghai Guangzan Light Steel Houses achieve stable indoor temperatures of around 26℃ in summer and over 18℃ in winter in container houses through thickened insulation layers (e.g., 100mm polyurethane) paired with air conditioning systems. Additionally, designs such as adjustable sunshade canopies and bottom ventilation slots can reduce direct sunlight and ground moisture impact, further enhancing comfort.
