Abstract:
1. A building facade construction comprising: a surface of a building wall; a porous three dimensional matrix filamentous polymeric mat having a first face and a second face, the polymeric mat being manufactured from a thermoplastic polymer wherein the polymeric mat comprises a plurality of filaments that are heat fused to one another at randomly spaced points to form a three-dimensional body, and wherein the first face contacts the building surface or a building paper layer overlying the building surface; a fiberglass mesh layer comprising a first plurality of fiberglass filaments disposed in a spaced apart and parallel relationship to each other, and a second plurality of fiberglass filaments disposed in a spaced apart and parallel relationship to each other, and wherein the first plurality of filaments is bonded to the second plurality of filaments in a substantially perpendicular orientation, the fiberglass mesh layer having a first face and a second face wherein the first face of said fiberglass mesh layer is bonded to the polymeric mat second face, wherein the polymeric mat and the fiberglass mesh layer are bonded together to form a unitary structure prior to being installed on the surface of the building, the unitary structure being movable, positionable and installable as a single unit and being suitable for being provided in rolled form for ease of transport; and a building facade layer comprising one or more components, at least one of the components impregnating the fiberglass mesh layer, the building facade layer being supported by the fiberglass mesh layer in combination with the polymeric mat; the unitary structure comprising a continuous conduit for water drainage.
