rock wool sandwich panel supplier

Coastal or rainy regions often experience high salt spray, high humidity, strong ultraviolet radiation, and frequent rainfall, which directly accelerate the corrosion, aging, core material moisture absorption, and sealant aging of sandwich panels.   The durability of sandwich panels with different core materials and coatings varies in coastal/rainy regions, as compared below: 1. Fluorocarbon coated high-zinc PIR sandwich panel: Service life 15-25 years, up to 25 years with regular maintenance; ideal for cold storage, industrial plants, and clean rooms in coastal high-salt-spray and tropical rainy areas; 2. Polyester coated ordinary galvanized PU sandwich panel: Service life 8-10 years, 10-15 years in inland rainy areas; suitable for ordinary factories and warehouses in inland rainy areas; 3. Polyester coated rock wool sandwich panel: Service life 5-8 years; insulation performance significantly decreases after 3-5 years in high humidity environments. This product is only suitable for ordinary factory buildings in dry areas and is not recommended for use in coastal or rainy areas.   In summary, for coastal and rainy regions, it is recommended to choose PIR sandwich panels with a high zinc layer and fluorocarbon coating. Their durability fully meets the needs of the building's entire life cycle, making them the optimal choice for steel structure building envelope systems, especially suitable for building scenarios in tropical coastal and rainy countries in Southeast Asia such as Indonesia.  

Sandwich panels, used for walls and roofs, are widely used in various steel structure factories, large warehouses, clean rooms, logistics warehousing, and cold storage facilities due to their excellent thermal insulation performance, high strength, good waterproof performance, light weight, easy installation, and short construction period. The significant advantages of sandwich panels are as follows:   1. Excellent thermal insulation performance: Sandwich panels typically use EPS, rock wool, and polyurethane as insulation core materials, providing excellent insulation performance without the need for additional insulation layers;   2. High structural strength, wind resistance, and strong corrosion resistance: Sandwich panels use color-coated galvanized steel sheets as the base material, resulting in high structural strength and good wind resistance. The surface can be coated with highly weather-resistant and fluorocarbon coatings, offering good corrosion resistance and aging resistance;   3. Excellent sound insulation and fire resistance: Different sandwich panel core materials can be selected to meet different application requirements. For example, large logistics warehouses can choose Class A fire-resistant rock wool core materials; large computer rooms can choose glass wool core materials with good sound insulation; and cold storage can choose polyurethane core materials with better thermal insulation performance.   4. Good sealing and waterproofing: Sandwich panels are generally sealed with tongue and groove joints and sealant, resulting in good waterproofing performance.   5. Lightweight, quick construction, and short construction period: Compared with traditional wall panels, sandwich panels are lighter and suitable for light steel structures and roof and wall renovations. They can be directly assembled on-site, simplifying construction, shortening the construction period, and greatly reducing labor costs.   6. Beautiful appearance and high cost performance: The surface of sandwich panels is made of color steel plate, which can be designed and selected in different colors, making them beautiful and elegant. Furthermore, color steel plates have a long service life, are easy to maintain, and offer high overall cost performance.
