Fireseal loose stonewool insulation is specifically designed for sealing gaps between service pipes and penetrations through concrete floors, providing exceptional fire resistance and thermal insulation performance.

• Sealing gaps between service pipes and concrete floor penetrations
• Requires placement in fire-rated pillows for temporary service protection
• Recommended for use with fire collars for PVC pipes
• Ideal for fire resistance and thermal insulation applications

Manufactured from natural rocks (basalt and dolomite) melted at high temperatures to form a molten matrix, then processed through an air stream to create long fibrous strands. The material is chemically and biologically inert, free from plant pathogens, and available in 10kg or 15kg packaging options.

• Exceptional fire resistance with 1-4 hour endurance ratings
• Superior thermal insulation properties
• Non-combustible material with zero flame spread
• Low moisture absorption (<0.5%) and minimal shrinkage (<1%)
• Non-corrosive and chemically inert composition
