Protective drainage wraps

Abstract

A protective drainage wrap comprises a polymeric spunbonded portion being adapted to allow water vapor to flow therethrough and a plurality of fibers, filaments, tapes or yarn being attached to the polymeric spunbonded portion. The plurality of fibers, filaments, tapes or yarn forms a plurality of channels to assist in forming a drainage path for draining liquid moisture from the protective drainage wrap.

1 . A protective drainage wrap comprising a polymeric spunbonded portion being adapted to allow water vapor to flow therethrough; and a plurality of fibers, filaments, tapes or yarn being attached to the polymeric spunbonded portion and forming a plurality of channels to assist in forming a drainage path for draining liquid moisture from the protective drainage wrap.  
     
     
         2 . The protective wrap of  claim 1  wherein the polymeric spunbonded portion is a polyolefin spunbonded portion.  
     
     
         3 . The protective wrap of  claim 2  wherein the polyolefin spunbonded portion is polyethylene, polypropylene or the combination thereof.  
     
     
         4 . The protective wrap of  claim 1  wherein the polymeric spunbonded portion includes polyester, nylon or the combination thereof.  
     
     
         5 . The protective wrap of  claim 1  wherein the plurality of fibers, filaments, tapes or yarn comprises polypropylene, polyethylene or combinations thereof.  
     
     
         6 . The protective wrap of  claim 1  wherein the plurality of fibers, filaments, tapes or yarn is yarn.  
     
     
         7 . A method of using a protective wrap in a building, the method comprising the acts of: 
 providing a protective wrap including a polymeric spunbonded portion and a plurality of fibers, filaments, tapes or yarn, the polymeric spunbonded portion being adapted to allow water vapor to flow therethrough, the plurality of fibers, filaments, tapes or yarn being attached to the polymeric spunbonded portion and forming a plurality of channels to assist in facilitating a drainage path for draining liquid moisture from the protective drainage wrap;    providing at least one framing member; and    installing the protective wrap over at least one of the framing members.    
     
     
         8 . The method of  claim 7  further comprising providing an exterior covering selected from siding, brick, masonry, stucco or concrete veneer and installing the exterior covering over the protective wrap.  
     
     
         9 . The method of  claim 7  wherein the at least one framing member is plywood or oriented-strand board.  
     
     
         10 . The method of  claim 7  further including providing a sheathing, the sheathing being located between the protective wrap and the at least one framing member.  
     
     
         11 . A method of using a protective wrap in a building, the method comprising the acts of: 
 providing a protective wrap including a polymeric spunbonded portion and a plurality of fibers, filaments, tapes or yarn, the polymeric spunbonded portion being adapted to allow water vapor to flow therethrough, the plurality of fibers, filaments, tapes or yarn being attached to the polymeric spunbonded portion and forming a plurality of channels to assist in facilitating a drainage path for draining liquid moisture from the protective drainage wrap;    providing a sheathing; and    installing the protective wrap over the sheathing.    
     
     
         12 . The method of  claim 11  further comprising providing an exterior covering selected from siding, brick, masonry, stucco or concrete veneer and installing the exterior covering over the protective wrap.  
     
     
         13 . A method of forming a protective drainage wrap, the method comprising the acts of: 
 providing a polymeric spunbonded portion being adapted to allow water vapor to flow therethrough; and    attaching a plurality of fibers, filaments, tapes or yarn to the polymeric spunbonded portion and forming a plurality of channels to assist in facilitating a drainage path for draining liquid moisture from the protective drainage wrap.    
     
     
         14 . The method of  claim 13  wherein the polymeric spunbonded portion is laminated to the plurality of fibers, filaments, tapes or yarn.  
     
     
         15 . The method of  claim 13  wherein the polymeric spunbonded portion is attached to the plurality of fibers, filaments, tapes or yarn via an adhesive.  
     
     
         16 . The method of  claim 13  wherein the polymeric spunbonded portion is thermobonded to the plurality of fibers, filaments, tapes or yarn.
