Patterned bonding of encapsulation material to an insulation assembly

摘要

An insulation assembly includes an elongated batt of fibrous insulation material having a top end and a bottom end, and a facing secured on a major surface. The facing is secured to the major surface by a series of spaced apart adhesive ribbons, wherein the adhesive ribbons are oriented generally transversely of the insulation assembly, and are nonlinear in a generally downwardly-oriented concave shape.
