Abstract: The present invention provides a lath furring strip having improved water-resistant and insulation features. The lath furring strip has portions of the mounting leg height not exceeding 0.365 inches for proper plastering of a wall. The lath furring strip is integrated into other architectural structures such as reveals, expansion joints and window flange coverings. By integrating these structures with a lath furring strip having water proofing features, there is increased water proofing of the entire architectural structure. One or more moisture barriers can easily be applied to the wall or furring strips that prevents seepage of moisture from the stucco on the lath to a wall or framing. By using an improved lath furring strip, fewer penetrations are needed to secure the furring strip to a wall compared to securing a lath directly to a wall.

Abstract: The present invention provides a lath furring strip having a height not exceeding 0.365 inches which has a flexible elastic water resistive barrier (e.g. rubber) to minimize water seepage from the plaster on the lath to a structure behind the lath furring strip and a hemmed mounting leg to increase the strength of the mounting leg near the lath attachment hole. By incorporating a flexible elastic water resistive barrier into the lath furring strip, when the flexible elastic waterproof barrier on the lath furring strip is squeezed by the force of a screw or nail that secures the lath furring strip to a sheathing or moisture barrier (such as building paper), any holes in the sheathing or moisture barrier which might have allowed water to seep from the plaster to the sheathing will be sealed due to the properties of the flexible elastic water resistive barrier covering those holes.
