FAQs

Q: What is a Rock Wool Composite Panel with PU edge?

A: It is a composite building material consisting of a rock wool core and polyurethane edge sealing structure. The PU edge enhances structural stability, and resistance to moisture, while the rock wool core maintains excellent fire protection and thermal insulation.

Q: Can the panel be disassembled and reused?

A: Yes, the modular design allows disassembly and reuse if the panel is not damaged. However, the PU edge and sealing structure may need to be reprocessed to ensure performance.

Q: Is the panel environmentally friendly and non-toxic?

A: Yes. Rock wool core is made by melting natural basalt and other minerals, free of formaldehyde, benzene and other harmful volatile substances, and no toxic gases when burned; the PU edge uses flame-retardant polyurethane without formaldehyde or heavy metals.
