Patent ID: 7556849

Claim:
A faced insulation assembly, comprising: a glass fiber insulation blanket having a first major surface and a second major surface that are each defined by the length and width of the glass fiber insulation blanket, wherein the glass fiber insulation blanket has lateral edges extending along the length of the glass fiber insulation blanket, wherein the glass fiber insulation blanket comprises at least one longitudinally extending separable connector connecting two adjacent longitudinal sections of the glass fiber insulation blanket; a facing formed from a kraft paper sheet material having an outer major surface and an inner major surface, the facing further having lateral edge portions, the lateral edge portions being adjacent to the lateral edges of the glass fiber insulation blanket, wherein the facing comprises at least one line of weakness that is longitudinally aligned with the at least one lonuitudinally extending separable connector; and an asphalt coating layer on the inner major surface of the facing that bonds the facing to the first major surface of the glass fiber insulation blanket, wherein the asphalt coating layer does not extend to the lateral edges of the glass fiber insulation blanket such that the lateral edge portions of the facing are not bonded to the first major surface of the glass fiber insulation blanket by the asphalt coating layer, wherein the asphalt coating layer is not present in regions between the at least one longitudinally extending separable connector and the at least one line of weakness, and wherein the asphalt coating layer consists essentially of an asphalt or a blend of asphalts, and an odor-reducing additive of at least one essential plant oil in an amount sufficient to substantially eliminate odor that would otherwise be emitted by the asphalt coating layer without adversely affecting the adherent qualities of the asphalt coating layer.
