Gray water-ripple textured polyurethane exterior wall sandwich panels are metal-faced composite insulation panels, formed in one go by a polyurethane (PU) edge-sealing process using upper and lower colored metal sheets (color-coated steel, aluminum-magnesium-manganese, or stainless steel) and a central core. A special profiling process creates a water-ripple/orange-peel texture on the surface, balancing both decorative and functional qualities. They are primarily used for integrated insulation, fire protection, and decorative systems on building exterior walls.

The core advantages of Gray Water Pattern Textured Polyurethane Sandwich Panel for Exterior Walls are:
1. Excellent Fire Resistance
Class A Fire Resistance: Rock wool core with polyurethane edge banding offers fire resistance exceeding 1000°C and meets international fire protection standards (such as ISO, BS, and DIN).
Test Data: 50mm thick panels achieve a fire resistance of REI 30, while 100mm thick panels reach REI 1205.
2. Highly Effective Thermal Insulation
The thermal conductivity is as low as 0.043W/(m·K) (rock wool core), and polyurethane edge banding further reduces thermal bridges.
3. Strong Sealing and Waterproofing
Polyurethane edge banding addresses rock wool's moisture absorption problem. The double tongue-and-groove design ensures seamless overlap, and concealed buckle joints prevent leaks.
4. Convenient and Efficient Construction
Daily installation area reaches 600–800m². Supports concealed nail-type horizontal installation, reducing on-site processing.
5. High Strength and Durability
Polyurethane improves overall rigidity after curing, providing high compressive and flexural strength. The surface coating (fluorocarbon PVDF, polyester PE) provides excellent weather resistance.
Gray Water Pattern Textured Polyurethane Sandwich Panel for Exterior Wall application scenarios and application cases
1. Locations with high fire protection requirements: Pharmaceutical laboratories, electronics factories, and food processing workshops (Class A fire protection required).
2. Large public buildings: Airport terminals (significantly reduce flight noise), gymnasiums, and cold storage facilities.
3. Energy-saving renovation projects: Integrated exterior wall insulation and decoration systems, particularly suitable for regions with extremely cold or hot climates.
4. High-end commercial buildings: Shopping malls and office buildings (water-ripple texture enhances the facade aesthetics).
