Patent ID: 8404330

Claim:
A metallized, moisture vapor permeable sheet consisting of: a moisture vapor permeable sheet layer having first and second outer surfaces, the sheet layer comprising at least one of a nonwoven fabric, woven fabric, nonwoven fabric-film laminate, woven fabric-film laminate, moisture vapor permeable film and composites thereof, wherein the first outer surface of the moisture vapor permeable sheet layer is a porous sheet selected from the group consisting of microperforated films, woven fabrics and nonwoven fabrics; at least one metal coating on said first outer surface of the sheet layer which substantially covers the outer surfaces of the porous sheet while leaving the pores substantially uncovered, said metal coating comprising an alloy selected from the group consisting of aluminum/bronze alloys, manganese/bronze alloys, copper/nickel/zinc alloys, copper/nickel alloys, stainless steel, and aluminum/magnesium alloys, having a thickness between about 15 nanometers and about 200 nanometers adjacent the first outer surface of the sheet layer; and an intermediate organic coating layer selected from the group consisting of polymers, oligomers or combinations thereof, having a thickness between about 0.02 micrometer and 0.6 micrometers disposed between said first outer surface of the sheet layer and said metal coating wherein the intermediate organic coating layer is vapor deposited on said first outer surface of the sheet layer.
