A vapor permeable, water impermeable film is coating partially with an
adhesive surface coating. The partial adhesive coating is deposited on
both surfaces of the film and coated areas on one surface of the film are
at least partially in line with the coated areas of the second surface. A
three ply laminate sheet is manufactured having a middle layer consisting
of a vapor permeable water impermeable films having partial surface
