How to install polyurethane edge banding rock wool board?

I. Core Advantages of Polyurethane Edge Banding Rock Wool Board

1. Enhanced Performance:

• Class A Fireproofing + Superior Insulation: Rock wool core meets fire safety standards, while polyurethane edges eliminate thermal bridging (thermal conductivity ≤0.038W/(m·K)).
• Improved Airtightness: Sealed joints reduce air leakage, boosting energy efficiency (airtightness increased by ≥30% in tests).
• High Load-Bearing Capacity: Vertical compressive strength ≥15kPa, ideal for large-span roofs and walls.

2. Cost-Effective Installation:

• Prefabricated Design: Minimizes on-site cutting waste, increasing installation efficiency by 40%.
• Lightweight Structure: 15% lighter than traditional composite panels, reducing transport and lifting costs.

II. Key Joint Methods Explained

1. Tongue-and-Groove Joint (Recommended)

• Features: Interlocking grooves ensure continuous sealing, perfect for high-airtightness applications (e.g., cleanrooms, cold storage).
• Installation Tips:
  • Overlap width ≥50mm, fill grooves with polyurethane foam sealant.
  • Avoid sealing strips when fixing with self-drilling screws.

2. Flat Joint (Budget-Friendly)

• Applications: Temporary structures or low-wind-pressure areas.
• Sealing: Cover seams with waterproof tape + external metal fasteners.

3. Concealed Joint (Premium Projects)

• Benefits: Hidden connectors eliminate exposed screws, ensuring smooth aesthetics (e.g., airports, stadiums).
• Tools Required: Aluminum alloy H-clip systems.

III. Standardized Installation Process (6 Steps)

Step 1: Substrate Inspection & Layout

• Check steel purlin flatness (tolerance ≤3mm/m), mark reference lines.

Step 2: First Panel Alignment

• Start installation from eaves/corners, following “roof-first, walls-later” sequence.

Step 3: Panel Fixation Techniques

• Self-Drilling Screws: Spacing ≤300mm, screw vertically into purlin C-channel centers.
• Concealed Clip System: Use sliding brackets to accommodate thermal expansion.

Step 4: Seam Sealing

• Apply continuous polyurethane sealant (width ≥8mm).

Step 5: Reinforcement at Critical Nodes

• Add U-shaped trims around door/window openings; stagger joints at corners.

Step 6: Final Inspection

• Use thermal imaging to detect thermal bridges; air leakage ≤1.5m³/(h·m²) at 50Pa pressure.

Q1: How does polyurethane edge banding rock wool board installation differ from traditional rock wool panels?

► Avoid cutting sealed edges; pre-drill holes at the factory.

Q2: How to prevent edge degradation in humid climates?

► Use UV-cured polyurethane edges (25+ years durability).

Q3: How to secure panels on roofs with >10% slope?

► Add anti-slip clips (≥6 fixings per m²).
