Facing system for an insulation product

An insulation product comprising an elongated batt of fibrous insulation material, and a facing adhered to a major surface of the batt, wherein the facing is a coextruded polymer film having a barrier layer between a bonding layer and a third layer, with the bonding layer having a softening point lower than the softening point of the barrier layer, and with the third layer having a high friction surface for good printability, wherein the facing has been heated to a temperature above the softening point of the bonding layer, but below the softening point of the barrier layer, whereby the facing is adhered to the batt by the attachment of the bonding layer to the fibers in the batt due to the softening of the bonding layer.

A method of making an insulation product comprising:

• positioning a coextruded polymer film in contact with a major face of an elongated batt of fibrous insulation material, wherein the coextruded polymer film includes a carrier layer between a barrier layer and a bonding layer, and with the bonding layer having a softening point lower than the softening point of the barrier layer;
• and
• heating the coextruded polymer film to a temperature above the softening point of the bonding layer, but below the softening point of the barrier layer, while maintaining the coextruded polymer facing in contact with the batt to soften the bonding layer to an extent sufficient to attach the bonding layer to the fibers in the batt and thereby adhere the coextruded polymer facing to the batt.

An insulation product comprising an elongated batt of fibrous insulation material and a coextruded polymer facing adhered thereto, wherein the coextruded polymer facing is a coextruded polymer film is a coextruded polymer film including a carrier layer between a barrier layer and a bonding layer, wherein the coextruded polymer facing has been heated to a temperature above the softening point of the bonding layer, but below the softening point of the barrier layer, whereby the coextruded polymer facing is adhered to the batt by the attachment of the bonding layer to the fibers in the batt due to the softening of the bonding layer.

A method for installing an insulation product comprising:

• providing an insulation product comprising an elongated batt of fibrous insulation material, and a facing adhered to a major surface of the batt, wherein the facing is a coextruded polymer film of barrier and bonding layers, with the bonding layer having a softening point lower than the softening point of the barrier layer, and wherein the facing has been heated to a temperature above the softening point of the bonding layer, but below the softening point of the barrier layer, whereby the facing is adhered to the batt by the attachment of the bonding layer to the fibers in the batt due to the softening of the bonding layer, and wherein the facing has no flanges;
• and
• installing the insulation product in an insulation cavity by pressing the insulation product into place between opposed structural members.
