• Glass wool has a thermal output superior than mineral wool, but an inferior work zone, arriving at 450o C maximum limit.
• In mineral wool, superior zones in use of up to 830ºC can be found, depending in all density cases.
• The ceramic fiber aplication can stand temperatures until 1400ºC, it can be used in high performance machines.
