PU-Edge Sealed Rock Wool Sandwich Panel

The PU-Edge Sealed Rock Wool Sandwich Panel is a high-performance composite panel that combines the fire resistance of rock wool with the airtightness of polyurethane edge sealing. Rock wool serves as the core insulation material, while the four edges are sealed with PU foam, ensuring a continuous, thermal-bridge-free structure with superior fire safety, moisture resistance, and thermal insulation.

Available Surface Options: Flat, Corrugated, Embossed Orange Peel Texture, Square Ribbed, Quad-Lock Edge.

Product Description

Compared with Standard Rock Wool Sandwich Panels:

Standard rock wool panels have exposed edges that are prone to moisture penetration and thermal bridging. PU edge sealing significantly improves overall airtightness and moisture resistance, resulting in tighter joints and more stable performance—ideal for energy-efficient and hygiene-sensitive environments.

Compared with PU (Polyurethane) Sandwich Panels:

While PU panels offer excellent insulation, rock wool cores provide superior fire resistance (non-combustible, Class A), making them a safer choice for fire-regulated buildings. They also offer better acoustic performance at a more economical cost for large-scale applications.

Applications

Used in industrial workshops, storage rooms, and utility areas with high fire safety requirements, offering A-grade fire resistance and partitioning capabilities.

Applied in food processing plants, pharmaceutical workshops, and cleanrooms where fireproofing, sound insulation, and moisture resistance are required under GMP compliance.

Ideal for cold storage and temperature-controlled logistics centers; PU edge sealing enhances airtightness and thermal bridge resistance.

Used in modular buildings like mobile rooms, prefab medical units, and rapid-deployment structures requiring lightweight and stable enclosure systems.
