Thermal Insulation Roof of Container House

The thermal insulation roof of a container house can achieve efficient thermal insulation by selecting appropriate materials, optimizing structural design, and applying thermal insulation solutions, as detailed below:

Select Appropriate Materials

The key to thermal insulation in container houses lies in material selection. The outer layer of anti-corrosion color-coated steel plate can reflect sunlight, the middle layer with polyurethane foam over 50mm thick can effectively block heat conduction, and the inner layer of fire-resistant gypsum board combined with a moisture-proof film can stabilize indoor temperature and humidity. Additionally, using sandwich panels with an aluminum foil reflective layer can further enhance the effect of reflecting sunlight and reduce indoor temperature.

Optimize Structural Design

By optimizing the roof structure, thermal insulation performance can be improved. Raising the roof increases the space for air circulation, forming a natural thermal insulation layer and effectively reducing indoor temperature. For example, container houses in San Antonio, Texas, USA, have significantly improved thermal insulation by raising the ceiling and incorporating structural insulated panels (SIPs) and autoclaved aerated concrete (AAC) blocks. The triangular roof structure, with a combination of metal panels, translucent materials, and steel louvered shutters, not only protects occupants from heat and rain but also allows natural light to penetrate and air to circulate, preventing heat from accumulating in the room.

Apply Thermal Insulation Solutions

Reflective thermal insulation coatings are a cost-effective and efficient thermal insulation solution. Their silver-white coating can reflect most infrared radiation, reduce heat absorption by the cement roof, lower the roof surface temperature by more than ten degrees Celsius, and reduce indoor temperature by 3-5℃. During application, the roof should be cleaned first, cracks repaired, and the waterproof layer ensured to be intact before rolling on the coating 2-3 times. Increasing foam thickness or using rock wool are also effective thermal insulation methods. For example, increasing the thickness of polystyrene foam or using rock wool as a thermal insulation material during the construction of container houses can enhance thermal insulation performance.
