Mineral wool is described as insulation material made of wool of glass and stone wool. It is applicable from the cellar up to the roof in a new building or at the renovation of old buildings.
Mineral wool consists of at least 90 per cent of local mineral raw materials like limestone, feldspar, dolomite, basalt, diabase, sand and cement which are gained from natural stocks, as well as e. g. of recycled glass. The availability of the natural raw materials which are processed to mineral wool is almost unlimited. Up to seven per cent of mineral wool is of organic substance and binders which essentially consist of synthetic resin components.
The mineral raw materials are melted and then span to fibres at approx. 1400 to 1500 degrees centigrade in two different methods. A binder solved into water is sprayed on the fibres during this process. The fibres cool down fast and stiffen glassily. The binder is then hardened in a tunnel stove at approx. 250 degrees centigrade by which the products get their structure stability. Now they can be cut on measure.
The raw material need for the production is so low that from a cubic meter of raw material up to 150 cubic metres (m³) are gained. This amount is sufficient for the insulation of approx. three detached houses.
Mineral wool stands out due to its excellent material qualities and various ranges of application. It is a product won of natural raw materials which offers protection from cold and warmth, absorbs sound and offers an optimal fire protection. In addition, mineral wool is without problems due to its simple handling and physically quite safe for the health, very insusceptible to ageing, as well as highly economical.
