Embodiment Construction

[0035] While the description and drawings disclose insulation products made of fiberglass insulation, it should be understood that the insulation may be any compressible fibrous insulation such as rock wool, polypropylene or polyester.

[0036] As shown in Figure 1, a conventional wall structure, generally indicated at 10, includes a base plate 12 upon which a plurality of supports 14 rest. The four sides of the insulating wall cavities 16 , 18 and 20 are defined by a floor, supports and a not shown ceiling. The front and back of the wall cavity are usually made with drywall inside and foam protection outside, neither of which is shown. Wall cavity 16 may be considered a non-standard wall cavity because its width is much narrower than that of a standard wall cavity. Making the wall cavity 16 would require cutting the insulation product to narrower widths. The insulating effect of the insulating cavity 18 is not good enough, because the exhaust pipe 22 passes vertically in th...

Abstract

An insulation product includes an elongated batt (110) of fibrous insulation material, and a facing (64) adhered to a major surface of the batt. The facing is a coextruded polymer film of barrier (80) and bonding (82) (and preferably carrier (84)) layers, with the bonding layer having a softening point lower than the softening point of the barrier layer. The bonding layer can include one or more of ethylene N-butyl acrylate, ethylene methyl acrylate, low density polyethylene and ethylene ethyl acrylate. When 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, 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. The heating can be either conduction heating or ultrasonic heating. For ultrasonic heating, the bonding layer is resonant at a different ultrasonic frequency than the barrier layer. The insulation product can be singly-faced (60) or doubly-faced (1424), and the edges of the double-facing can be joined to form an encapsulated product.

Description

technical field [0001] This invention relates to fibrous insulation products, particularly of the type suitable for insulating buildings. More specifically, this invention relates to insulation products having a facing system that provides a vapor barrier and / or facilitates handling of the insulation product. The invention also relates to techniques for attaching facing systems to insulation products. Background technique [0002] Fibrous insulation is generally formed by fiberizing the melt and depositing the fibers on a collecting conveyor. While some insulation products are manufactured from organic fibers such as polypropylene and polyester, typically, the fibers used in insulation products are mineral fibers such as fiberglass. Most fibrous insulation products contain a binder material that binds the fibers together so that they touch each other to form a grid or network. The adhesive provides the resilience to the insulation product, allowing it to return to its ori...
