What is claimed: 1. An insulation for high temperature applications, comprising glass fibers having an average fiber diameter of between about 2.7 to about 3.8 microns, said insulation being substantially free of thermoplastic fibers and having an average density of between about 0.5 lb/ft3 and about 6.0 lb/ft3, wherein the thermal conductivity of said insulation at 500 degrees F. is less than the thermal conductivity of an insulation material having an average density substantially the same as said insulation and glass fibers with an average fiber diameter greater than said glass fibers of said insulation.
