Thermal Insulation Renderings of Container Houses

Currently, thermal insulation renderings of container houses cannot be provided directly, but their thermal insulation effects and principles can be described in text.

Impact of Different Thicknesses of Thermal Insulation Wall Panels on Thermal Insulation Performance
According to the measured data from Zeyu Shijia, the thermal insulation performance of container houses is closely related to the thickness of the wall panels. Among the three thicknesses of 50mm, 75mm, and 150mm, the thicker the wall panel, the more significant the thermal insulation effect. For example, a 150mm-thick wall panel can more effectively maintain indoor temperature in low-temperature environments. When combined with sealing and heating measures, the habitability is significantly improved. This rule indicates that by increasing the thickness of the thermal insulation layer, the heat exchange rate between the indoor and outdoor environments can be significantly reduced, thereby improving energy efficiency.

Application Effect of Polyurethane Thermal Insulation Panels
The 6-meter container house refitted by Shandong Junan Xinwang Container Factory uses a 7-centimeter polyurethane thermal insulation panel as the core thermal insulation layer, with an additional 12-centimeter-thick layer of other materials stacked on top and bottom. Polyurethane, due to its closed-cell structure and high thermal conductivity coefficient (approximately 0.022-0.028 W/(m·K)), has become an efficient thermal insulation material. This structure further blocks the heat conduction path through a multi-layer composite design, enabling the house to maintain a higher indoor temperature in cold environments and reduce heating energy consumption.

Synergistic Effect of High-Efficiency Thermal Insulation Materials and Sealed Structures
The thermal insulation temporary container houses from Guangdong Aishangguizu Integrated Housing use rock wool, polyurethane, and other materials to fill the walls, roofs, and floors, forming a continuous thermal insulation layer. The thermal conductivity coefficient of rock wool is approximately 0.032-0.044 W/(m·K), while that of polyurethane is even lower. The combination of the two can cover a wider temperature range. Paired with double-glazed windows (with a thermal conductivity coefficient of approximately 0.5-1.0 W/(m²·K)) and sealed structures, the house reduces convective and radiative heat transfer, achieving dual effects of summer heat insulation and winter thermal insulation. Actual measurements show that such houses can maintain stable indoor temperatures in extreme weather conditions, reducing air conditioning or heating energy consumption by 30%-50%.

Summary
The thermal insulation effect of container houses depends on the thickness and type of thermal insulation materials as well as the sealing design. Thick wall panels, polyurethane/rock wool filling layers, double-glazed windows, and sealed structures are key elements for improving thermal insulation performance, effectively addressing temperature challenges in different climatic conditions.
