ABSTRACT:
A faced fibrous insulation having a mat facing on one or more surfaces of a fibrous insulation material 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 that 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.
