PU Sealing Glass Wool Sandwich Panel
PU Sealing Glass Wool Sandwich Panels combine thermal efficiency, acoustic insulation, and fire resistance into a single lightweight solution. The PU edge sealing enhances airtightness, prolongs panel lifespan, and reduces maintenance costs. With high compressive strength and excellent durability, they support both structural and partition applications. Their compliance with international fire and thermal standards ensures safety in critical environments such as cleanrooms and cold storage. Additionally, their modular design allows rapid installation, reducing labor costs and downtime. Environmentally, glass wool contributes to sustainability through recyclability and reduced energy demand, making these panels an optimal choice for modern construction.
PU Sealing Glass Wool Sandwich Panels are advanced composite construction materials designed for thermal insulation, acoustic control, and structural integrity. By integrating glass wool as the core material and polyurethane (PU) sealing on the edges, these panels provide superior energy efficiency, enhanced fire resistance, and long-term durability. They are widely adopted in industrial buildings, cleanrooms, cold storage, and commercial facilities, where regulatory compliance and performance are critical.
Composition and Engineering Principles
Core Material: Glass wool, known for its low thermal conductivity (~0.035 W/m·K) and high sound absorption coefficient (>0.75 NRC).
Surface Layers: Galvanized steel, aluminum, or pre-coated sheets for weather and corrosion resistance.
PU Edge Sealing: Prevents moisture ingress, minimizes thermal bridging, and improves air-tightness.
Structural Performance
Load-bearing capacity: Up to 1.5–2.0 kN/m² depending on thickness and span.
Dimensional stability: PU sealing ensures reduced deformation under fluctuating temperature and humidity.
Fire behavior: Glass wool achieves Euroclass A1 rating, while PU sealing maintains joint integrity under fire exposure.
Regulatory Compliance and Standards
PU Sealing Glass Wool Sandwich Panels are engineered to meet international construction and safety standards:
EN 13501-1: Fire classification of building materials.
ASTM C518: Thermal conductivity test.
ISO 140-3: Sound insulation performance.
FM Approval: For insurance compliance in industrial buildings.
Regulatory compliance ensures safe use in public infrastructure, clean environments, and high-risk facilities.
Applications
Cleanrooms – PU sealing prevents dust and microbial infiltration.
Industrial Buildings – Walls, ceilings, and partitions for factories and warehouses.
Cold Storage Facilities – Superior insulation reduces energy consumption.
Commercial Projects – Shopping malls, office partitions, and acoustic barriers.
Operational Considerations
Installation: Panels must be joined with precision to maintain airtightness.
Maintenance: Regular inspection of PU seals prevents deterioration.
Environmental Impact: Glass wool is recyclable and contributes to sustainable construction.
