House Insulation Container Specification

The specifications for house insulation containers mainly cover aspects such as material performance, structural design, installation, and acceptance. They need to meet relevant national standards to ensure insulation effects and safety.

Material Performance Specifications

• Wall Materials: The heat transfer coefficient of the walls of residential containers must be ≤0.45W/(㎡·K), which is 1.8 times the insulation efficiency of traditional brick-and-mortar walls. Commonly used materials have a three-layer structure: an outer layer of anti-corrosion color-coated steel plate reflects sunlight, a middle layer of over 50mm polyurethane foam blocks heat conduction, and an inner layer of fire-resistant gypsum board + moisture-proof film works together to control humidity and stabilize temperature. Some products use sandwich panels with aluminum foil reflective layers to further enhance insulation performance.
• Sandwich Panel Selection: Poor-quality sandwich panels, due to their high thermal conductivity and poor structural tightness, can lead to cold interiors in winter and hot interiors in summer, increasing energy consumption. High-quality suppliers need to clarify material selection criteria (such as the density and thickness of color-coated steel sandwich panels) and processing techniques to ensure insulation stability.
• Auxiliary Materials: Rock wool and polystyrene foam can also be used for insulation layers, but they need to be selected according to the usage scenario. For example, a new material processed from polystyrene foam and black steel plate has significant insulation effects.

Structural Design Specifications

• Modular Design: Container houses need to achieve spatial expansion through the combination of container bodies. The design must conform to the principle of modular coordination to ensure reasonable planar and spatial layouts that meet different functional requirements such as living and office use.
• Structural Stability: The container body must have load-bearing capacity (e.g., a 20-foot container can bear 25T, and a 40-foot container can bear 45T) and adapt to multiple disassembly and assembly requirements. The design of structural nodes needs to strengthen the openings and reinforcement of the container walls to avoid a decrease in airtightness due to disassembly and assembly.
• Ventilation and Shading: Some designs use adjustable shading roofs, bottom ventilation slots, and air inlets and outlets to regulate temperature using natural wind, reducing reliance on artificial cooling/heating.

Installation and Acceptance Specifications

• Sealing Detection: During installation, it is necessary to focus on checking the joints between panels, the fit between doors, windows, and frames, and the sealing treatment of corners to avoid a decrease in insulation performance due to the cold bridge effect.
• Fire Prevention and Anti-corrosion: Materials must meet combustion performance requirements (such as the combustion characteristics of insulation materials in Appendix C), and the steel structure parts need to undergo anti-corrosion treatment to extend their service life.
• Acceptance Standards: According to the Technical Regulations for Modular Combination Container Houses, on-site installation allowable deviations, rust removal and coating quality, etc., must all comply with the specifications to ensure that the house is safe, applicable, and economically reasonable.
