A protective drainage wrap comprises a porous layer, a breathable solid layer portion and a plurality of fibers, filaments, tapes or yarn. The porous layer is adapted to allow water to pass therethrough. The breathable solid layer portion is adapted to allow water vapor to pass therethrough while preventing or inhibiting water from passing therethrough. The plurality of fibers, filaments, tapes or yarn is located between and attached to the porous layer and the breathable solid layer portion. The plurality of fibers, filaments, tapes or yarn forms a plurality of channels to assist in forming a drainage path for draining liquid water from the protective drainage wrap. |
