ROCKWOOL is made of basalt by high-temperature melting. Thanks to its A1-grade non-combustible rating, strong sound insulation, and high-temperature resistance, it enjoys the soubriquet "King of Fireproof Insulation" among architects and engineers worldwide. Its main applications include:

 

1.Exterior Wall Insulation (dry-hanging curtain walls, thin plaster systems)

High-density rock wool boards (≥120kg/m³) are the first choice for high-rise building curtain walls, which can meet the most rigorous fire protection standards: China's GB 8624, EU's EN 13501.

2.Roof Insulation

Roofs of rock wool board with buffer layer can be used for insulation of steel structure and concrete roof with the pressure-resistance ≥60kPa and no collapse within 25 years.

 

3.Fireproof Partitions and Steel Structure Fire Protection

Fireproof partition walls, elevator shafts, and steel beams and columns are wrapped with rock wool. The fire resistance limit of this type of application is 1-4 hours.

 

4.High-Temperature Industrial Equipment

Rock wool pipe shells can resist high temperatures up to 650℃. They have a wide application range in the insulation of marine, petrochemical, and power plant pipelines.

 

5.Top-Level Acoustic Engineering

Essential for recording studios, theaters, and concert venues, rock wool has an NRC ≥ 0.9, well over glass wool and foam.

 

6.Planting and Soilless Cultivation

Agricultural-grade rock wool blocks are breathable and water-retaining; therefore, it is considered the golden substrate for greenhouse vegetable cultivation in Europe.
