ABSTRACT:
The present invention is an insulation material with improved loft characteristics and methods for producing such insulation. The preferred insulation comprises a multiple layered insulation material with discrete fibers having energy expandable thermoplastic microspheres interspersed and contained therein. The use of expandable microspheres allows for (1) the introduction of unexpanded microspheres into pro-constructed insulation; and (2) expansion of the microspheres within the insulation to a diameter greater enough that the microspheres are retained in place. The insulation of the present invention exhibits many improved properties over conventional insulations, such as improved loft, better thermal insulation, improved compression resistance, and improved resilience.
