The Insulation Technology of Container

The original function of the container is the freight. While it is used as a building space carrier, there is need for external envelope structure of heat insulation technology and the airtight treatment of doors and windows etc. Only in this way can we create the pleasant, livable indoor environment.

The external walls, roofs, doors and windows of container houses should meet the following basic functional requirements and the relevant national standards:

1)Heat insulation, sound insulation, waterproof impermeability, air tightness and other requirements;

2)Environmental protection requirements;

3)Resist earthquake, wind, fire, lightning and other security requirements;

4)Decorative and comfortable requirements;

5)recyclable requirements.

Enclosure insulation treatment refers to “prevent indoor heat flow to the outside the in the case of indoor and outdoor temperature difference during winter”, so that the room can maintain the appropriate temperature; heat insulation treatment can make the room to maintain the appropriate temperature in case of the outdoor high temperature and direct sunlight during summer.

In the transformation of container housing envelope structure, we should adopt light and efficient insulation materials and should also meet the corresponding building fire resistance requirements. At present, the most common container insulation materials include:rock wool board, glass wool board, extruded polystyrene foam, molded polystyrene foam and rigid polyurethane foam and other materials.

Thermal insulation material performance depends on the quality of the thermal conductivity of the material. Thermal conductivity is inversely proportional to glass wool board temperature insulation performance. That is to say, the better the thermal insulation material performance, the smaller the thermal conductivity. The same insulation material, the greater the thickness, the higher the performance, but because of the fixed internal space of the container housing , so the choice of thermal insulation materials should be a small thermal conductivity of high thermal insulation materials, and reduce the thickness the thickness of the thickness , in order to improve the effectively-used indoor area.

The top insulation and energy-saving technology of the container building: we can implant artificial turf in the roof, or make solar heating roof, by which we can convert the light energy into the energy used by the container. During summer, the container space is closed, and the metal shell by direct sunlight to produce indoor high temperature, thus, we can add an air insulation layer at the top of the container.
