1. A method of forming an insulation product, comprising:
forming a continuous sheet of paper into a plurality of flexible loops defining a plurality of air channels extending in a direction that is substantially perpendicular with a machine direction of the continuous sheet of paper; and
immediately attaching a first layer of paper and a second layer of paper to the plurality of flexible loops as they are formed so that the continuous sheet of paper retains the plurality of flexible loops between the first layer and the second layer and that the plurality of flexible loops remain unattached with respect to one another.
