Product Overview
Polyurethane exterior wall cladding panels combine continuous exterior thermal insulation with an architectural finish. Comprising a rigid polyurethane (PUR/PIR) foam core bonded between structural facings, these composite panels eliminate thermal bridging and deliver immediate weatherproofing for commercial, industrial, and modular building envelopes.

Key Features
Continuous Insulation (CI):
Closed-cell core structure meets ASHRAE 90.1 thermal envelope requirements.
High Compressive Strength:
≥ 150 kPa core strength prevents surface indentation during installation and wind loads.
Vapor Retarder:
Impermeable facing prevents moisture migration into the framing cavity.
Tight Dimensional Tolerances:
± 1.5 mm in length and ± 0.5 mm in thickness ensure flush joint alignment.
Applications
Cold Storage Facilities:
High thermal resistance prevents internal temperature loss.
Industrial Warehouses:
Rapid horizontal/vertical installation minimizes structural dead loads.
Commercial Facades:
Matches strict architectural aesthetics and local energy codes.
Modular Construction:
Lightweight sandwich structure integrates directly onto steel chassis frames.
Customization Capabilities
Cut-to-Length:
Factory precision cutting eliminates on-site trimming.
01
Asymmetric Facings:
Configurable combinations (e.g., metal exterior, foil interior).
02
Pre-punched Details:
Factory-machined fastener clearance slots.
03
Engineering Support:
Wind load calculation reports provided per project zone.
04
Manufacturing & Quality Control
Continuous Lamination Line:
High-pressure foaming injection ensures uniform cell density without voids.
Curing Control:
Heated double-belt press maintains a 12-minute constant temperature profile for complete matrix cross-linking.
Peel-Strength Testing:
In-house shear and peel testing verifies metal-to-core bond integrity, backed by third-party audit reports.
Compliance:
Produced under ISO 9001; panels carry CE marking and ASTM test documentation.
Installation & Joint System
Tongue-and-Groove Interlock:
Precision male/female joint profile with factory-applied butyl sealant beads.
Concealed Fastening:
Clip-fixed system accommodates thermal movement without exposing screw heads.
Sub-framing Compatibility:
Mounts directly to cold-formed steel purlins and aluminum sub-grids.
Packaging & Logistics
Surface Protection:
Peel-off PE protective film on both faces.
Stacking Security:
Separated with EPS spacers, edge-protected, and secured with high-tensile steel strapping.
Container Optimization:
40'HC container loads up to 2,500 m² (thickness-dependent) to minimize freight costs.
