3.1 Non-textile fibers made of glass wool rock wool and mineral wool as well as ceramic wools

Glass fibers produced with diameters in the range of 0.1 pm to 20 pm have become particularly important. Since lengthwise fracturing is not to be expected, these fibers only conditionally lie within the range for penetration to the lungs. Based on their compatibility, the residence time in the organism is relatively short.

Application areas for these mineral fibers are in the loose form in stuffing insulations, mats, felts and sheets, as well as in fibrous filling materials in the areas of fire protection, thermal insulation, noise or vibration insulation, filtration, friction linings and also chemical products and fibrous cement.

Glass fiber concrete (Heidelberger Zementwerke AG) is made of a cement-bound matrix and alkali-resistant, highly firm glass fibers. This material produced in a mixing concrete process has very good properties, especially for facade elements, because of its high bending tensile strength, high impact resistance, corrosion resistance and its good ductility. Its relatively low weight and high fire resistance (Fire Class Al) enable the manufacturing of complicated and multi-functional building parts.
