Abstract
An insulation component for use in an airplane, comprising a first fibrous layer having a first density and a second fibrous layer chemically bound to the first fibrous layer. The second fibrous layer has a second density less than the first density. The first and second fibrous layers comprise a similar material. The first density provides the insulation component with enough rigidity to be self-supporting. The average fiber diameter of the fibers in the first and second fibrous layers is less than 2 μm.
