Abstract
A nonwoven fibrous insulation product has at least a bi-modal fiber diameter distribution designed to provide the product with selected thermal insulating and physical performance properties that are affected by fiber diameter such as rigidity and recovery properties. The product is made by: forming two or more fiber groupings that each have a selected fiber diameter distribution with a selected mean fiber diameter wherein the selected fiber diameter distributions of the fiber groupings differ from each other. The fibers of the fiber groupings are intermingled and entangled together in selected percentages by weight to form a product with a selected density and thickness that exhibits selected product performance properties based on the properties of the fiber groupings and the relative percentages by weight of the fiber groupings.
