Concept Insulation composite panels are made by combining color-coated steel sheets or other panel materials with a bottom plate and an insulating core using adhesives or foaming techniques. These composites offer excellent thermal performance and structural integrity, making them ideal for a wide range of industrial and commercial applications. Composite methods include explosive bonding, roll bonding, and other advanced techniques. Composite materials can be categorized into plates, pipes, rods, and more, and are widely used in industries such as petrochemicals, pharmaceuticals, construction, automotive, and more due to their durability and functional properties. Applications 1. Industrial plants and warehouses 2. Cold storage facilities and packaging boxes 3. Light steel residential buildings and mezzanines 4. Mobile offices and temporary structures 5. Cleanrooms, air conditioning rooms, and other controlled environments Advantages 1. Lightweight, weighing approximately 10-14 kg per square meter—equivalent to just 1/30 the weight of traditional brick walls. 2. Excellent thermal insulation, sound absorption, and sealing properties. 3. Easy to install, reducing construction time by over 40%. 4. Attractive appearance with vibrant colors, eliminating the need for additional surface finishing. 5. High strength and structural stability, suitable for load-bearing and maintenance structures, allowing for beam and column-free designs in many cases. Main Board Materials 1. Surface or floor materials (such as color-coated steel, galvanized sheet, stainless steel, aluminum foil, PVC, and plywood) 1.1 Properties of Different Sheets (1) Color-Coated Steel Sheet Typically made from hot-dipped or galvanized steel substrates, with a durable paint finish that resists peeling. For composite panels, high-quality two-coat one-bake or two-coat two-bake finishes are preferred. Poor quality sheets with issues like loose edges, uneven coating, or large irregularities should not be used. (2) Galvanized Sheet Offers good corrosion resistance, but may require additional surface preparation for optimal bonding. (3) Stainless Steel Sheet High corrosion resistance, but challenging to process and bond effectively. Surface treatment is often required for better adhesion. (4) Aluminum Foil Paper Composed of reinforced aluminum foil with glass fiber ribs between layers. It provides fire-resistant, durable, and aesthetically pleasing insulation, ideal for modern thermal and acoustic insulation systems. (5) PVC Foam Board Manufactured from polyvinyl chloride (PVC), it features a smooth surface, lightweight, flame resistance, moisture resistance, and easy cutting. It also offers good weather resistance and chemical resistance, making it easy to clean and maintain. (6) Plywood While cost-effective, plywood has limitations in length and compactness, leading to potential cracking issues during use. Main Core Materials 2. Core Material (e.g., EPS, rock wool, glass wool, flame-retardant honeycomb panels, polyurethane, etc.) 2.1 Overview of Different Core Materials (1) Foam Board (EPS) Made from expandable polystyrene (EPS) particles, which are pre-expanded and then molded into a closed-cell structure. It’s lightweight and commonly used for insulation purposes. (2) Polyurethane Known for its superior thermal insulation and fire-resistant properties. The density of polyurethane used in composite panels typically ranges from 30 to 40 kg/m³. (3) Rock Wool Board Produced from basalt and other natural minerals, processed into inorganic fibers. It is non-combustible, offering excellent fire protection and insulation performance. (4) Glass Wool A lightweight, heat-resistant, and elastic material widely used in industrial, commercial, and transportation sectors. It excels in insulation, fireproofing, and sound absorption. (5) Flame-Retardant Honeycomb Panel A B1-class fireproof material with strong compressive strength, no toxic emissions, and recyclability. It serves as an eco-friendly alternative to wood, especially for use with polystyrene, polyurethane, and rock wool cores. (6) Polyurethane Another top-tier material known for its fireproof and insulation capabilities, often used in composite panels at a density of 30–40 kg/m³.
