Container House Sandwich Rock Wool Panel
The container house sandwich rock wool panel is a composite panel made with rock wool as the core material, featuring fire resistance, thermal insulation, sound absorption, and other properties. It is widely used in container movable houses and industrial building fields.
Core Materials and Structure
The container house sandwich rock wool panel is a type of rock wool sandwich panel. Its core structure consists of two layers of metal panels (such as color-coated steel sheets and stainless steel sheets) on the top and bottom, and a rock wool core material in the middle, which are bonded together with high-strength adhesives. Rock wool is an inorganic material made from natural ores like basalt. After being melted at high temperatures, it is spun into fibers. It has characteristics such as non-combustibility (Class A fire resistance), a low thermal conductivity (approximately 0.036 - 0.040W/(m·K)), and a high sound absorption coefficient (NRC≥0.85). This structure endows the panel with both the strength of the metal panels and the functionality of the rock wool, meeting the requirements of container houses for lightweight and durability.
Performance Advantages
- Fire Safety: The melting point of the rock wool core material exceeds 1000℃, and its combustion performance reaches the Class A non-combustible standard. It can effectively block the spread of fire, meeting the strict fire safety requirements of container houses.
- Thermal Insulation: The low thermal conductivity enables the panel to maintain stable thermal insulation performance in environments ranging from - 50℃ to 450℃, reducing heat exchange between the inside and outside of the container and lowering air conditioning energy consumption.
- Sound Absorption and Noise Reduction: The porous structure of the rock wool fibers can absorb sound wave energy, reducing indoor noise levels and being suitable for scenarios with specific acoustic environment requirements.
- Moisture and Corrosion Resistance: The metal panels are galvanized or coated, and combined with the hydrophobicity of the rock wool (water absorption rate ≤ 5%), they can resist corrosive environments such as humidity and salt spray, extending the service life.
Application Scenarios
In addition to container movable houses, this panel is also widely used in the roofs and walls of steel structure factories, partitions in simple movable houses, and ceiling systems in clean rooms. Its modular design facilitates quick installation and disassembly, adapting to diverse needs such as temporary buildings, industrial factories, and commercial exhibition halls.
Market Supply
Currently, brands that provide rock wool sandwich panels for container movable houses in the market include Xigu, Jingkaili, and Zhongjiang Lvjian. The product specifications cover a series of thicknesses from 50 - 150mm and densities from 80 - 150kg/m³. Users can select appropriate models according to climate conditions, fire ratings, and other requirements.
