Thermal Insulation of Tianjin Container Houses

The thermal insulation performance of Tianjin container houses is excellent, mainly achieved through wall materials, structural design, and sealing techniques for efficient thermal insulation and heat preservation.

1. Wall Materials and Thermal Insulation Structure

Tianjin container houses commonly use fire-resistant thermal insulation composite panels as wall materials, such as composite EPS thermal insulation wall panels. These panels feature a lightweight steel structure as the framework, filled with high-density thermal insulation materials (e.g., expanded polystyrene EPS), and covered with metal or fire-resistant panels on the exterior, forming a multi-layer composite structure. Their core advantages include:

1. Low Thermal Conductivity: The thermal conductivity of EPS and other thermal insulation materials is extremely low, effectively blocking heat transfer between the interior and exterior. This reduces heat loss in winter and lowers air conditioning loads in summer.
2. Fire Resistance: Flame retardants are added to the composite panels to meet building fire safety regulations. Additionally, the thermal insulation layer is tightly integrated with the structural layer, preventing the thermal insulation layer from detaching in case of fire.
3. Lightweight and High Strength: The panels are lightweight, facilitating easy transportation and installation, while possessing high compressive strength to withstand external impacts.

2. Overall Structure and Sealing

Container houses feature a fully welded structure, with steel frameworks fixed to walls and roofs using bolts or rivets, creating a closed space. Their sealing is enhanced through the following designs:

1. Waterproofing Techniques: Seams are treated with sealing strips or waterproof coatings to prevent rainwater infiltration and reduce heat loss caused by air convection.
2. Window and Door Systems: Equipped with double-glazed windows and sealed door frames, these systems further reduce heat conduction. Sunshades or thermal insulation curtains can be added as needed.
3. Floor Thermal Insulation: Some products lay thermal insulation panels or reflective films on the ground base to block the cold bridge effect from the floor, improving overall thermal insulation performance.

3. Application Scenarios and Performance Verification

The thermal insulation performance of Tianjin container houses has been verified in practical scenarios:

1. Extreme Environment Adaptability: In coastal or high-humidity areas, houses must possess both moisture resistance and thermal insulation capabilities. Falilai products ensure long-term dryness and effectiveness of the thermal insulation layer by optimizing wall drainage structures and using moisture-resistant coatings.
2. Energy-Saving Data Support: According to supplier information, their container houses can reduce energy consumption by over 30%, with indoor temperatures 5-8°C higher in winter and 3-5°C lower in summer compared to traditional temporary buildings.
3. Modular Expandability: The thermal insulation performance remains unchanged regardless of the house combination method. When single units or multi-story stacks are used, sealing connectors between units maintain overall thermal insulation continuity.

4. Purchase Recommendations

To further optimize thermal insulation performance, consider the following details:

1. Panel Thickness: Choose thicker thermal insulation layers (e.g., EPS panels over 100mm thick), but weigh the costs against space requirements.
2. Additional Systems: Install solar water heating systems or ground-source heat pumps to utilize renewable energy for auxiliary thermal insulation.
3. Manufacturer Qualifications: Prioritize suppliers with ISO thermal insulation certifications to ensure material performance meets national standards.
