Abstract: A multiple sheet building wrap for wrapping the structural components of a building in order to protect the underlying structural components and optional building sheathing from moisture is provided. The building wrap is particularly useful under facades such as wet applied stucco or engineered stone, demonstrating good drainage of liquid water and moisture vapor permeability. The building wrap is a composite of a water resistive barrier, a three-dimensional mesh layer and a porous intervening layer which acts to filter the stucco as it is applied. An exterior wall construction incorporating such building wrap is also provided.

Abstract: Stretchable material with recovery properties that are waterproof and conformable in two or three dimensions particularly adapted for flashing in structures, especially at the bottom and lower corners of openings where water is likely to collect. A method of installing flashing materials in openings in structures.
