Methods of forming insulation mats including: providing a mixture of fibers comprising first inorganic fibers and second inorganic fibers, wherein the first inorganic fibers shrink by no more than about 2 percent and the second fibers shrink by about 5 to about 15 percent when the mixture of fibers is heat treated; wet-forming a web of fibers from the mixture of fibers; entangling the web of fibers to form an insulation mat; heat-treating the insulation mat; and drying the web of fibers and/or the insulation mat after said wet-forming and prior to or during said heat treating; and wherein the insulation mat includes substantially no non-fibrous binder material prior to said heat treating the insulation mat at a temperature of from about 500° C. to about 800° C., optionally for at least about 3 minutes. Insulation mats manufactured according to the above methods.

The insulation mat of claim 16, wherein the first inorganic fibers are present in the mixture of fibers in an amount of at least about 80 percent by weight. 18. The insulation mat of claim 16, wherein the second inorganic fibers are present in the mixture of fibers in an amount of up to about 20 percent by weight. 19. The insulation mat of claim 16, wherein the first inorganic fibers comprise at least one of biosoluble fibers or refractory ceramic fibers. 20. The insulation mat of claim 16, wherein the second inorganic fibers comprise at least one of silica fibers, S-glass fibers, S2-glass fibers, E-glass fibers or fiberglass fibers. 21. The insulation mat of claim 16, wherein the first inorganic fibers shrink by no more than about 2 percent when heat treated at a temperature of from about 500° C. to about 800° C. 22.
