General Lapinus engineered fibres are produced at our Rockwool plant in Roermond, The Netherlands. Different types of natural volcanic rock and man-made briquettes with a well-defined chemistry are the major raw materials. The use of briquettes and the combination of different types of raw materials ensure the consistent chemical composition of the fibres. 

In the first stage, the raw materials are melted in a furnace at a temperature of approximately 1600°C (2900°F) to a homogenous mass. This lava is then directed from the bottom of the furnace to the spinning wheels. When a controlled stream of lava falls on the spinning wheel, drops of lava are launched and form long fibres with a non-fibrous melt droplet, called shot, at the start of the fibres. During the production the fibres can be treated with various types of coatings. The long fibres (granulate) are collected in bales and form the base material for the production of Lapinus engineered fibres. In the next production step, the shot is removed and the fibre length is adapted. If needed the cleaned fibres can be given an additional surface treatment.

The exhaust gases from the production furnace and spinning chamber are cleaned in filters and after-burners before entering the chimney. The waste created during the production is recycled.
