1. Product Introduction
Rock wool serves as the core material of the panel and delivers excellent fire‑resistance performance, making it suitable for factories, warehouses and public buildings with high building fire‑safety requirements. Polyurethane edge sealing is applied to the panel edges and joint zones, which reduces heat transfer and enhances sealing performance at panel seams.
This structure is not a simple superposition of two materials. Instead, it is optimized to solve thermal insulation and sealing issues at rock‑wool panel joints, enabling the wall to maintain favorable overall performance after on‑site installation.

3. Why Choose PU‑sealed Rock‑Wool Sandwich Panels?
Many projects rely on standard rock‑wool panels for basic fire protection, yet overlook issues such as heat leakage, water ingress and broken insulation at panel joints. Polyurethane‑edge rock‑wool sandwich panels solve these common drawbacks. The rock‑wool core delivers reliable fire safety, while peripheral polyurethane sealing creates tighter joints with continuous insulation and lower risk of moisture condensation.
Available with various facing sheets, the panels suit general factories, warehouses, as well as food and pharmaceutical clean‑room environments. Factory pre‑fabrication enables fast on‑site assembly. Balancing safety, energy efficiency and construction speed, they are well‑suited for building projects with higher quality expectations.
4. PU-sealed Rock‑Wool PV Roof Sandwich Panels
Solar roof panels integrate building roof enclosure with solar power generation. Different insulation cores, metal face sheets and connection structures can be adopted according to building structures and project requirements, with pre‑reserved fixing positions for solar modules. Thanks to outstanding fire resistance and thermal insulation performance, polyurethane‑edge rock‑wool sandwich panels are widely used for building roofs equipped with solar PV systems.
