Glass fiber felt made of silica and alumina oxides. Extremely resistant at high temperatures (up to 600°C), chemically stable, electrically and acoustically insulating. These fibers are also inorganic, fireproof and they have a low density. The diameter of the silica fibers (nine micron on average) brings to this type of textiles great elasticity and resistance to vibrations and abrasion. These products are available in different thicknesses (from 4 up to 25 mm) or custom made. Usable as insulator for high temperatures.
