AI Overview
PU Rock Wool Sandwich Wall Panels are advanced composite building materials designed for high-performance thermal insulation, superior fire resistance, and soundproofing, commonly used in industrial, commercial, and cleanroom applications. These panels consist of a high-density rock wool core, which provides non-combustible A-grade fire resistance, with both edges sealed with rigid Polyurethane (PU) foam, offering better water resistance, airtightness, and structural strength compared to standard rock wool panels.
Key Features and Performance
- Fire Safety: Core material is non-combustible (Class A1), with the PU-sealed sides offering superior fire performance up to Class A, preventing flame spread.
- Thermal Insulation: The core provides good insulation, with U-values ranging from 0.20 to 0.63 W/m²K depending on the thickness.
- Waterproofing & Air-tightness: The PU-edge sealing creates a continuous, water-resistant, and airtight structure, preventing moisture absorption by the rock wool and eliminating thermal bridges.
- Structure & Strength: Composed of galvanized or aluminum steel sheets on both sides with high-density rock wool (100–120 kg/m³ or higher) in the middle.
- Sound Insulation: Excellent acoustic performance (sound insulation ≥ 30dB), making them ideal for noise reduction, with Noise Reduction Coefficients (NRC) often ranging from 0.80 to 0.95.
- Dimensions: Available in thicknesses from 50mm to 200mm, with typical effective widths of 950mm, 1000mm, or 1150mm.
Main Advantages
- Faster Installation: Prefabricated to fit design requirements, reducing installation time by over 40%.
- High Durability: Corrosion resistance (C1-C3 classes) and a robust design ensure a long lifespan.
- Aesthetic Appearance: Hidden joint connections provide a flat, seamless appearance for modern façades.
