On our press line, the stone wool is being pressed into a high-density board. For the binding of the stone wool fibres, a small amount of thermosetting resin is used. This creates a panel with a low calorific content and very good reaction to fire performance.
Production waste is fully utilised in this process: every piece of stone wool that’s cut off, goes back into our recycling process and is used to create new stone wool fibres. And thanks to our unique and highly efficient manufacturing process, we are able to produce more than 400 m² Rockpanel boards from only 1 m³ of basalt.
