Insulation products and methods and machines for making insulation products

An insulation product, comprising:

• a first layer and a second layer;
• and
• a paper core formed into a plurality of flexible loops comprising a first flexible loop, a second flexible loop, and a third flexible loop with the first and third flexible loops contacting each other proximate the first layer and the second flexible loop disposed between the first and third flexible loops proximate the second layer, and
• wherein the paper core is disposed between and attached to the first layer and the second layer.

An insulation product, comprising:

• a first layer;
• and
• a first continuous paper sheet formed into a first plurality of flexible loops disposed on and attached to the first layer and defining a first plurality of air channels that extend in a direction that is substantially perpendicular with a machine direction of the insulation product,
• wherein the insulation product has an indentation force deflection of 1.5 to 180 pounds per square inch at 50% thickness reduction, and
• wherein the insulation product has an R-value of 1.3 to 1.7.
