An improved lath is disclosed having a water drainage layer provided in association with the lath. The water drainage layer serves to remove water that might otherwise build up between the lath and wall structure.
Claims20
A construct for drainage and structural support of a wall, the construct comprising:
- a matrix lath having a front side, a back side, a first plurality of filamentous elements arranged in a first direction, and a second plurality of filamentous elements arranged in a second direction substantially perpendicular to the first direction, wherein the first plurality of filamentous elements and the second plurality of filamentous elements together form a surface having peaks and valleys;
- and
- a water channel layer having a front side and a back side, wherein the front side of the water channel layer is joined with the back side of the matrix lath, and wherein the water channel layer is formed from a matrix of randomly oriented, non-absorbent, fibrous elements that define a path for water passing through the water channel layer from a top to a bottom thereof.
A method of assembling a construct for drainage and structural support of a wall, the method comprising:
- positioning a back side of a matrix lath in opposition to a front side of a water channel layer, wherein the matrix lath comprises a first plurality of filamentous elements arranged in a first direction and a second plurality of filamentous elements arranged in a second direction substantially perpendicular to the first direction, wherein the first plurality of filamentous elements and the second plurality of filamentous elements together form a surface having peaks and valleys, and wherein the water channel layer is formed from a matrix of randomly oriented, non-absorbent, fibrous elements that define a path for water passing through the water channel layer from a top to a bottom thereof;
- and
- joining the back side of the matrix lath with the front side of the water channel layer.
A method of installing a construct for drainage and structural support of a wall, the method comprising:
- trimming a section of the construct for drainage and structural support of the wall to a determined size, wherein the construct comprises:
- a matrix lath having a front side, a back side, a first plurality of filamentous elements arranged in a first direction, and a second plurality of filamentous elements arranged in a second direction substantially perpendicular to the first direction, wherein the first plurality of filamentous elements and the second plurality of filamentous elements together form a surface having peaks and valleys;
- and
- a water channel layer having a front side and a back side, wherein the front side of the water channel layer is joined with the back side of the matrix lath, and wherein the water channel layer is formed from a matrix of randomly oriented, non-absorbent, fibrous elements that define a path for water passing through the water channel layer from a top to a bottom thereof;
- placing the section of the construct on a building wall;
- and
- fastening the section of the construct to the building wall.
