Thermally insulated exhaust system components

A thermal insulating structure for thermally insulating at least a portion of a system component structure, with said thermal insulating structure comprising:

• a mixture comprising an inorganic binder, inorganic filler particles, and water;
• and
• a woven fabric comprising inorganic fibers in the form of a sheet- or mat-like structure, said woven fabric being impregnated with said mixture so as to form a pliable binder structure,
• wherein said pliable binder structure is dimensioned to be wound almost completely or at least once around at least a portion of the system component structure, and said inorganic filler particles comprise any particulate, when mixed with said inorganic binder in the presence of water, that causes a substantial portion of said inorganic binder to be retained in said woven fabric without forming a gel or otherwise coagulating such that said pliable binder structure becomes a solid mass before said pliable binder structure can be wound almost completely or at least once around said system component structure.

A thermal insulating structure for thermally insulating at least a portion of a system component structure, with said thermal insulating structure comprising:

• a mixture comprising an inorganic binder, inorganic filler particles, and water;
• a woven fabric comprising inorganic fibers in the form of a sheet- or mat-like structure, said woven fabric being impregnated with said mixture so as to form a pliable binder structure;
• and
• at least one thermal insulator comprising inorganic fibers, wherein said pliable binder structure is dimensioned to cover almost completely or all of the system component structure, and wherein said at least one thermal insulator is disposed such that, when said thermal insulating structure is applied, said at least one thermal insulator is disposed between said pliable binder structure and the system component structure.
