An insulation product contains a mixed layer of textile fibers and of rotary and/or flame attenuated fibers. A process for manufacturing the insulation product includes passing fibrous bundles of textile fibers and of rotary and/or flame attenuated fibers together through an apparatus that divides the textile fibers into segments and that mixes the textile fiber segments with the rotary and/or flame attenuated fibers. The bundles of rotary and/or flame attenuated fibers can be in the form of specially manufactured mats and/or can be production scraps. The resulting mixture of fibers is formed into a non-woven batt, mat, blanket, or board. The process provides a mixed fiber product, with an improved combination of thermal and acoustic insulating performance and adequate strength, at a low production cost.
