A flashing tape includes a moisture-impervious nonporous first layer having a drainage plane surface for providing drainage of moisture, the drainage plane surface being textured with embossed or otherwise raised spaced apart projections, the spaces between the projections, in conjunction with an overlay of construction material, defining a nondirectional flow path to permit the drainage of moisture and flow of air along said surface; a moisture-impervious second layer of closed cell polymeric foam which is bonded on a first side to the moisture-impervious first layer; and, a layer of pressure sensitive acrylic based adhesive applied to a second side of the moisture-impervious layer.
