Insulation products and methods and machines for making insulation products

An insulation product, comprising:

• a first layer comprising one or more first polymer-coated regions;
• and
• a second layer comprising one or more second polymer-coated regions;
• and
• a paper core formed into a plurality of flexible loops on the first layer and the second layer, the plurality of flexible loops comprising a first flexible loop formed on and attached to the one or more first polymer-coated regions of the first layer when formed, a second flexible loop formed on and attached to the second polymer-coated regions of the second layer when formed, and a third flexible loop formed on and attached to the one or more first polymer-coated regions of the first layer when formed, and wherein the second flexible loop is disposed between the first and third flexible loops proximate the second layer,
• wherein the paper core is disposed between and attached to the first layer and the second layer,
• wherein the paper core has a basis weight of about 18 lbs. per 3000 ft.2 to about 75 lbs. per 3000 ft.2, and
• wherein an axis, perpendicular to a length of the insulation product and parallel to a thickness of the insulation product, passes through (i) one of the one or more first polymer-coated regions of the first layer and (ii) the paper core at least three times.

An insulation product, comprising:

• a first layer comprising one or more first polymer-coated regions;
• and
• a first continuous paper sheet formed into a first plurality of flexible loops on the first layer, at least one flexible loop of the first plurality of flexible loops attached to the first layer at the one or more first polymer-coated regions when formed, and the first plurality of flexible loops 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,
• wherein the insulation product has an R-value of 1.3 to 1.7,
• wherein the first continuous paper sheet has a basis weight of about 18 lbs. per 3000 ft.2 to 75 lbs. per 3000 ft.2, and
• wherein a first axis, perpendicular to lengths of the first plurality of air channels and parallel to a thickness of the insulation product, passes through (i) one of the one or more first polymer-coated regions of the first layer and (ii) the first continuous paper sheet at least three times.
