Container House Insulation Module

Container house insulation modules typically use materials such as rock wool sandwich panels and polyurethane sandwich panels, combined with steel frame structures to achieve efficient thermal insulation performance. Some products further enhance heat insulation through multi-layer composite designs or special processes.

1. Core Insulation Materials and Structures

The core of container house insulation modules lies in the sandwich materials for walls and roofs. Rock wool sandwich panels are widely used due to their excellent fire resistance and thermal insulation properties. With a low thermal conductivity, they can effectively block heat transfer and meet Class A fire safety standards, ensuring high safety. For example, after using rock wool sandwich color steel plates in construction site temporary buildings in the mountainous areas of Guizhou, the indoor temperature can be 8-10℃ higher than the outdoor temperature, significantly improving comfort. Polyurethane sandwich panels are another common choice. Their closed-cell structure endows the material with good thermal insulation and waterproof properties, making them suitable for cold or humid environments. In addition, some high-end products use graphene EPS modules or phenolic foam boards to further reduce thermal conductivity and enhance energy-saving effects.

In terms of structure, insulation modules usually take a steel frame as the main body and combine it with the above-mentioned sandwich panels to form composite walls. The steel frame provides structural stability, while the sandwich panels are responsible for thermal insulation, fire prevention, and other functions. Some products also add aluminum foil thermal insulation layers or air layers inside the walls to enhance thermal insulation performance by reflecting thermal radiation or blocking heat convection.

2. Typical Products and Technical Features

1. Packing-box container houses
   These houses use hot-dip galvanized cold-formed steel sections as frames and are equipped with fire-resistant polyurethane sandwich panels. They can be used independently or stacked in multiple layers. Their thermal insulation performance meets the needs of construction site dormitories, office areas, and other scenarios. Moreover, they can be quickly assembled and disassembled, adapting to reuse across different projects.

2. Light steel keel houses
   These houses use cold-formed thin-walled light steel keels for load-bearing, with walls filled with thermal insulation materials such as glass wool or rock wool. The appearance of these houses can be flexibly customized, making them suitable for homestays and supporting facilities in scenic spots. The thermal insulation performance can be optimized by adjusting the density of the filling materials.

3. Modular insulated houses
   Some products use a combination of sandwich panels and steel structures, such as A-frame low-rise villas, achieving efficient thermal insulation through multi-layer material composites. These houses have a relatively low minimum order quantity, making them suitable for small projects or personalized needs.

3. Performance Optimization and Scenario Adaptation

The performance optimization of insulation modules needs to be combined with the usage scenarios. For example, in cold regions, the wall thickness can be increased or materials with lower thermal conductivity (such as phenolic boards) can be selected; in humid environments, polyurethane sandwich panels with strong waterproof properties should be preferred; in high-temperature regions, the heat absorption can be reduced by adding roof ventilation layers or reflective coatings. In addition, the modular design supports rapid deployment, with basic installation completed within 24 hours. Moreover, the material recycling rate is over 85%, which aligns with the concept of green buildings.
