ROCKWOOL products are used for all insulation applications, from industrial to domestic. ROCKWOOL building insulation key properties:
• Thermal insulation
• Noise suppression
• Fire resistant

ROCKWOOL has an open fibrous structure making it ideal for absorbing and regulating noise. It maintains the indoor climate of buildings leading to reduction in energy use for heating and cooling.


• EAF Steel Slag is valued for its high density (noise insulation) and fire-resistance properties, which are both vital characteristics of ROCKWOOL products
• Green material: avoids use of quarried materials, and avoids landfill of residual slag product
