<p>A faced fibrous insulation (10) having a mat facing (12) on one or more surfaces of a fibrous insulation material (16) is provided. The mat facing provides improved surface quality, high and controlled adhesion, and is easily manufactured. The mat facing of the present invention includes a pre-applied adhesive comprising a first adhesive (22) having a first melting point and a second adhesive (24) having a second melting point, wherein the first adhesive (22) is heat activated to provide adhesion to the fibrous insulation. The mat facing may be input into the glass fiber forming section of a fibrous insulation production line. Alternatively, the mat facing may be applied to the uncured pack prior to curing or applied to the cured fibrous insulation.</p> |
