Two ply paper lath over Tyvek house wrap, lathing information
Hello everyone, we used two ply paper to lath over Tyvek house wrap, this means 2 layer spot glued so they stay together for my weather resistive barrier. Its function is to prevent water from contacting the plywood sheathing and studs. Wet wood will rot while metal will rust. Therefore both must be kept dry. No one wants to deal with mold or mildew
The idea with 2 layer is that 2 layers offers a built in drainage plane for the wall system. So water can escape.
Another reason is if the outer layer fails you still have the inner layer. Plus 2 layers is just as easy to apply because it’s spot glued and won’t separate as you staple it up.
Defective stucco moisture barrier can cause water intrusion in walls, which leads to mold.
