Abstract

A method of making an insulation product of hollow fibers whereby molten insulation material is centrifuged through a plurality of orifices and gas is directed into the molten insulation material through a plurality of gas conduits, wherein each gas conduit directs gas into one of the portions of the molten insulation material being centrifuged through one of the orifices to form a hollow fiber having a hollow bore formed therethrough. The hollow fibers are combined to form the insulation product.
