density:40-200kg/m3 CE Certificate.
Insuring rockwool is a board product with certain strength. The product is mainly used for fireproofing and sound absorption of partition walls and curtain walls, thermal insulation of roofs, retaining structures and geothermal systems as well as thermal insulation and fireproofing of industrial kilns, ovens, large sized tanks and vessels, etc.
