Mineral stonewool fire insulation is a rigid board-form material engineered for comprehensive fire protection, thermal control, energy conservation, condensation prevention, and sound absorption in commercial building applications.

Manufactured from natural rocks including basalt and dolomite melted at high temperatures, mineral stonewool forms long fibrous strands through an air stream cooling process. The resulting chemically and biologically inert material is free from plant pathogens and recognized as an economical, lightweight thermal insulation solution.

Designed specifically for party wall applications, these batts effectively fill 50-100mm gaps between aluminum frames and concrete slab edges. For optimal fire control between floors, the curtain wall batts should be compressed by 15% of their thickness to ensure protection against fire and smoke ingress for adjacent occupants and property.

• Exceptional high temperature resistance up to 750°C working temperature
• Non-combustible with zero flame spread and smoke development
• Minimal moisture absorption (
• 1-4 hour fire endurance rating for comprehensive protection
• Non-corrosive and chemically inert properties
