Lath furring strips
View Patent ↗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.
1. A furring strip and insulation system for attaching a lath and an insulation layer to a wall, comprising:
a mounting plate having i) an exterior side, ii) an interior side that is substantially planar and designed to be placed substantially flush against a wall, and iii), a groove projecting outward from the exterior side of the mounting plate wherein the mounting plate has a mounting hole within the groove, the mounting hole extending from the exterior side to the interior side of the mounting plate;
a flexible elastic water resistive barrier disposed and retained wholly within the groove, said flexible elastic water resistive barrier characterized as having a complementary shape to the groove;
a mounting leg secured to, and extending substantially perpendicular from said mounting plate;
an insulation layer positioned against said exterior side of said mounting plate, said mounting leg passing through said insulation layer;
said mounting leg having at least one attachment hole for securing said lath to said furring strip;
whereby the positioning of said insulation layer between said lath and said mounting plate is advantageous because only the furring strip, and not the insulation layer, is penetrated to secure said furring strip to the wall, thereby protecting against water intrusion and thermal bridging.
2. The lath furring strip and insulation system of claim 1 , wherein said groove runs substantially across the length of said mounting plate.
3. The lath furring strip and insulation system of claim 1 , wherein,
said mounting leg has a top vertical edge; and,
the distance between said attachment hole and said top vertical edge of said mounting leg is not greater than 0.365 inches.
4. The lath furring strip and insulation system of claim 1 , further comprising:
a securing member, wherein said securing member traverses said mounting hole and penetrates said flexible elastic water resistive barrier.
5. The lath furring strip and insulation system of claim 4 , wherein said flexible water resistive barrier is a rubber gasket, and said securing member is a screw.
