What is a PU Sandwich Panel?
Polyurethane (PU) sandwich panels are composite building materials consisting of a rigid PU foam core sandwiched between galvanized steel or aluminum sheets. They combine:
• Thermal insulation – reduces energy costs and maintains stable indoor temperature.
• Acoustic insulation – reduces noise for a comfortable environment.
• Structural strength – supports heavy loads while remaining lightweight.
• Weather resistance – ideal for external and internal applications.
• Ease of installation – fast and labor-efficient assembly.
Key Advantages of Infinite Stars PU Panels
• Superior Insulation: Thermal conductivity of 0.023 W/m·K ensures high energy efficiency.
• Lightweight & Durable: Panels are easy to transport and maintain, with long service life.
• Fire Resistance: Meet B-s2,d0; NRO standards and EI 15 fire ratings.
• Customizable: Thickness (30–200 mm), length (2–12 m), steel thickness (0.3–1.0 mm), color (RAL options).
• Eco-Friendly: 100% recyclable materials, safe for humans and environment.
• Quick Installation: Streamlined process reduces construction time and labor costs.

Installation Guide
1. Preparation: Ensure personnel, tools, and materials are ready
2. Frame Check: Verify wall frame columns and purlins are vertical and level
3. Install Water Barrier: Attach bottom water-retaining plate and window base water-blocking board with self-tapping screws
4. Panel Connection:
• Horizontal: Fix one end with steel frame; overlap edges; fill any gaps with insulation
• Vertical: Use concave groove buttons to secure panels tightly
5. Final Inspection: Ensure alignment, insulation integrity, and overall stability
