Product Introduction

Traditional on-site masonry suffers from slow construction, high labor costs and inconsistent quality. This prefabricated factory-made panel delivers reliable fire resistance, sound insulation and thermal performance for prefabricated wall systems worldwide.

Applications

Widely applied in industrial warehouses, prefab offices, cold rooms and harsh environments resistant to corrosion and sandstorms. The rock wool panels can coordinate with EPS/PIR roof panels to build a complete building envelope.

How It Works - 3 Core Principles

1) Porous rock wool core locks static air → minimal heat transfer + inherent non-combustible insulation.
2) Composite skin+core evenly disperses wind & dead loads → stable structural integrity and deformation resistance.
3) Precise tongue-and-groove joints form a continuous barrier → reduce water infiltration, air leakage and thermal bridging (with proper sealing).

Key Advantages

Our Rockwool Sandwich Wall Panel adopt aluminum-zinc coated skins with superior corrosion resistance for coastal and desert areas. Featuring Class A fireproof, sound insulation and long service life, custom anti-corrosion options are available.

Certifications

Project case

This 3,800 m² electronics workshop in Mexico adopted our 75 mm rock wool wall panels. It achieves 30 dB sound insulation with 60% shorter construction time. Installation finished in only 12 days, and panels passed fire inspection at the first trial. Compared with traditional walls, the system ensures reliable fire & acoustic performance and cuts total cost by 28%.
