An attachment strip for attaching lath to a wall and a system for attaching lath to a wall with increased water resistive characteristics. The attachment strip has protruding teeth on an attachment plate that holds the lath in place, and a mounting plate that secures the lath furring strip against the wall and framing. In addition, since attachment strip, instead of the lath directly, is secured to the sheathing, fewer mounting devices are needed compared to when a lath is directly secured to a sheathing, where substantially more mounting devices would be needed. Thus in this arrangement, fewer penetrations are created when installing the lath. Additional water resistive features, such insulation layers, and a drainage space surrounded by two water resistive barriers, create space that not only increases insulation, but protects the inner layers of a wall from damage.
