Vapor-permeable, substantially water-impermeable, corrosion-inhibiting composites are disclosed herein. For instance, disclosed herein are composites comprising a first layer comprising a first nonwoven; and a second layer adjacent to and mechanically integrated with the first layer, the second layer comprising a polymer having a melt flow index of about 10 g/10 mins to about 200 g/10 mins, and a corrosion inhibitor, wherein the composite has a moisture vapor transmission rate of from about 25 g/m/day to about 1000 g/m/day when measured at about 23° C. and about 50% relative humidity. Also disclosed herein are methods of making and using the same.

Drainage promoting fabrics having commercial applications (e.g., housewrap) are provided. The drainage promoting fabric, according to certain embodiments of the invention, includes a weather resistive barrier having an outer surface, and a three-dimensional, non-uniform or non-continuous meltblown layer positioned on the outer surface of the weather resistive barrier. The meltblown layer may comprise meltblown shot, meltblown ropes, or both.
