AES wools consist of amorphous fibres, which are produced by melting a combination of CaO-, MgO- and SiO2 (see also EN 1094-1; VDI-recommendation 3469, Parts 1 and 5).
Products made from AES wools are generally used at application temperatures > 600 °C in industrial equipment, fire protection, automotive exhaust systems and domestic appliances. Their usage has grown significantly since their commercial production began in the early 1990s.
