Abstract: The water resistive barrier system may include a foam panel coupled to a frame of a building. The system may include a membrane above the foam panel. The system may include a scratch layer above the membrane. The system may include an exterior layer above the scratch layer. The system wherein the foam panel has a thickness between two and eight inches may have a structural tensile strength of 50 psi. In some embodiments, a method of manufacturing the water resistive barrier system may include providing a foam panel. The method may include coupling a membrane above the foam panel. The foam panel and the membrane can be manufactured as one panel. The method may include providing a scratch layer material for further coupling above the membrane during an installation. The method may include providing an exterior layer material for further coupling above a scratch layer during the installation.
