Rock Wool Composite Panel for Container Houses
The rock wool composite panel used in container houses is a composite material with rock wool as its core, offering both thermal insulation and fire resistance. It is widely applied for thermal insulation in walls, roofs, and other parts.
Composition and Structure of Rock Wool Composite Panels
Rock wool composite panels consist of two layers of cement or calcium silicate boards as the surface panels, with rock wool filling the intermediate layer. Rock wool is a fibrous material formed by centrifuging molten basalt and other natural ores at high temperatures, featuring excellent thermal insulation, fire resistance, and sound absorption properties. The cement or calcium silicate board surface panels not only enhance the overall strength of the panel but also provide a flat surface for easy subsequent construction and decoration.
Core Performance Characteristics
- Thermal Insulation: Rock wool has a low thermal conductivity (typically ≤0.040 W/(m·K)), effectively reducing heat transfer and lowering energy consumption in container houses, making it suitable for cold regions or areas with significant temperature variations.
- Fire Resistance: Rock wool is classified as a Class A non-combustible material with a melting point exceeding 1000°C. It does not burn or drip when exposed to fire and can absorb flame heat, slowing down the spread of fire and providing time for evacuation.
- Lightweight and High Strength: The panel has a low density (approximately 120-200 kg/m³) and weighs only one-fifth of traditional concrete panels, yet it has a compressive strength of 0.1-0.5 MPa, meeting the load-bearing requirements of container houses.
- Moisture and Corrosion Resistance: The outer cement or calcium silicate board is water-resistant, and the rock wool fibers have high chemical stability, making them less susceptible to moisture or corrosion and extending the panel's service life.
Application Scenarios in Container Houses
Rock wool composite panels are primarily used as thermal insulation layers for walls and roofs. In walls, they can replace traditional brick walls or color-coated steel sheets, reducing structural thickness while improving thermal insulation. In roofs, they are used in conjunction with waterproof membranes to form a complete thermal insulation and waterproofing system. Additionally, their flat surface allows for direct painting or the application of decorative panels, simplifying the renovation process.
Market Selection and Price Range
Rock wool composite panels for container houses come in various specifications on the market, with thicknesses typically ranging from 50-150mm and customizable dimensions. Prices vary significantly depending on brand, specifications, and configuration, with wholesale prices ranging from 112.20 yuan to 8500.00 yuan per unit. When selecting, attention should be paid to the rock wool density, surface panel material, and fire rating of the panels to ensure performance meets standards.
