Abstract
A fiber insulation product comprising hollow fibers. Each hollow fiber may be composed of at least two different thermoplastic insulating materials, such as glasses, having differing coefficients of thermal expansion, with each of the hollow fibers being an irregular-shape exhibiting a substantially uniform volume filling nature, and providing improved recovery and thermal conductivity abilities even in the absence of a binder material. An apparatus for making hollow fibers for such a product is also provided.
