Abstract
Insulative fabrics include a plurality of web layers. Each of the web layers comprises monostaple fibers having a length between about 0.5 and 2 inches. The plurality of web layers is positioned in overlying relationship and interconnected to each other (often through needle punching). In this configuration, the insulative non-woven fabric can provide a relatively low cost material with low thermal conductivity.
