Heatstroke in Container Houses

Container houses may experience excessively high internal temperatures due to inadequate thermal insulation in high-temperature environments, posing a risk of heatstroke. This can be mitigated through measures such as optimizing thermal insulation design, enhancing ventilation, and installing air conditioning.

Inadequate Thermal Insulation as the Primary Cause of Heatstroke

The main body of container houses is made of metal, which has high thermal conductivity. Without effective thermal insulation measures, the internal temperature can be significantly higher than the outdoor temperature during summer heat. For example, a regular container can reach an internal temperature of 42℃ when the outdoor temperature is 38℃, far exceeding the comfortable range for humans. The national 'Technical Standard for Steel Structure Integrated Houses' requires the heat transfer coefficient of walls in residential containers to be ≤0.45W/(㎡·K). However, some non-standard products use thin steel or inferior sandwich panels, resulting in substandard thermal insulation and increasing the risk of high temperatures.

Ventilation and Shading Design to Alleviate High Temperatures

Optimizing the ventilation structure (such as bottom ventilation slots and adjustable shading roofs) can reduce internal temperatures. For instance, a café in Moganshan uses sandwich panels with aluminum foil reflective layers, combined with shading roofs and ventilation slots, providing a comfortable feel even without air conditioning in the afternoon. However, such designs need to be tailored to specific climatic conditions and may have limited effectiveness in extremely high-temperature regions (such as the Middle East, where summer temperatures often reach 40-50℃), requiring additional auxiliary measures.

Air Conditioning Installation as a Necessary Configuration in High-Temperature Regions

In high-temperature and high-humidity or extremely hot regions (such as the Middle East), passive thermal insulation alone cannot meet the demand, and air conditioning is necessary to regulate the temperature. For example, Shandong Zhongjiang Green Construction provides container houses for construction sites with pre-installed air conditioning brackets and standardized electrical systems to ensure safety and effectively reduce the risk of heatstroke.

Regular Maintenance and Material Selection Affect Long-Term Performance

The service life and thermal insulation performance of container houses depend on regular maintenance (such as checking interface water tightness and painting for rust prevention) and the use of high-quality materials (such as marine-grade weather-resistant steel plates and Class A fire-resistant rock wool sandwich panels). The products of Weifang Jinruiyuan Steel Structure Co., Ltd. feature double-layer composite walls that provide thermal insulation and sound insulation (35-45dB), with built-in moisture barriers to adapt to humid climates, extending service life and maintaining stable performance.
