Manufacture of Mineral Wool

A look behind the scenes

Weiter

The production of our mineral wool products which are made of glass and rock wool is very similiar: from melting of the raw material to the fiber structure of the insulation materials. By centrifugal and by blowing process fibers are produced which are - while adding organic plastic resins - felted and formed into insulation products. In addition to the natural binder small amounts of mineral oil are added to bind the dust.
