Taming the volcano

• Stone wool production at the Rockwool factory is a highly sophisticated process
• The Rockwool process resembles the natural action of the volcano
• Environmental equipment makes the ‘tamed’ volcano an environmentally responsible process

The Rockwool process resembles the natural action of the volcanoStone wool is made by melting diabase rock and recycled briquettes, made with carefully selected by-products from our own and other industries, in a cupola furnace.  The melt is directed from the base of the furnace onto spinning wheels to form the Rockwool fibre structure.  Small amounts of binder and oil (typically 3% of total product content) are added to provide a stable, water repellent insulation product.  The stone wool is then heated to cure the binder before final processing into a variety of products.  Environmental equipment – filters, pre-heaters, after-burners and other cleaning collection systems – makes the ‘tamed volcano’ an environmentally responsible approach
