Water vapor breathable, liquid water resistant material

An insulation product comprising:

• an insulation layer containing randomly oriented fibers joined together with an adhesive;
• said insulation layer comprising, an R-value insulation or a duct liner board;
• and
• a facing applied to at least one major surface of said insulation layer, said facing comprising:
• a composite having three layers, comprised of, a water vapor permeable, substantially liquid water impermeable, porous polymeric film covered by an outer layer and further covered by a reinforcing layer;
• said film comprising one of, an extrusion coating or lamination, said film comprising polyurethane, which is spot bonded to said outer layer by melt bonds without adhesive;
• said outer layer comprised of, abrasion resistant, polymeric nonwoven fibers, wherein the polymeric fibers are melt bonded in the outer layer without adhesive;
• said reinforcing layer comprised of, a tear and puncture resistant, reinforcing mesh, said mesh being bonded without adhesive by melt bonds with said film to form said composite;
• and
• said composite having an ASTM D5035 tensile strength of at least about 100 N/5 cm, and exhibiting resistance to liquid water transmission.

An exterior finishing system, comprising:

• a composite having three layers, comprised of, a water vapor permeable, substantially liquid water impermeable, porous polymeric film between an outer layer and a reinforcing layer;
• said film comprising one of, an extrusion coating or lamination, said film comprising polyurethane, which is spot bonded to said outer layer by melt bonds without adhesive;
• said outer layer comprised of, abrasion resistant, nonwoven polymeric fibers, wherein the polymeric fibers are melt bonded without adhesive in the outer layer;
• said reinforcing layer comprised of, a tear and puncture resistant, reinforcing mesh, said mesh being bonded without adhesive by melt bonds with said film to form said composite;
• said composite being stapled to sheathing of a building to comprise an abrasion resistant and rain resistant housewrap;
• and
• a foam insulation board or an exterior sheathing material of said exterior finishing system over said composite, wherein said exterior sheathing material comprises one of, glass-faced gypsum board, siding, stucco, brick, stone or cement block.
