Abstract
A panelized lath and drainage plane panel and system is disclosed. A panel comprises a patterned polymer board providing a continuous drainage plane and a metallic lath affixed to the patterned polymer board, such that a first pair of adjacent edges include an exposed surface of the patterned polymer board. The panel may also include a second pair of adjacent edges, opposite the first pair of adjacent edges include an overhang of metallic lath. The system provides an open-air space between the exterior of the structure and the polymer board to allow the egress of liquid water and water vapor. A wall system using such panels is also disclosed. Typically, a manmade or natural stone veneer or a stucco is applied over the system.
Claims9
A lath and patterned polymer board panel for building exteriors, comprising:
- a rectangular patterned polymer board, the polymer board comprising:
- a base and a face defined by raised sections defining continuous hollows beneath the raised sections;
- and
- first and second pairs of adjacent edges;
- and wherein, when installed on a wall, the polymer board;
- is free from mortar holes capable of allowing mortar bridging or mortar droppings through the polymer board and toward the interior of the wall;
- and
- allows for the free passage of moisture through the continuous hollows, thereby avoiding the retention of moisture;
- and
- a rectangular lath panel affixed to the board, the lath panel comprising first and second pairs of adjacent edges, and wherein:
- the lath panel is arranged on the polymer board such that the first pair of adjacent edges of the lath panel overhang the first pair of adjacent edges of the polymer board;
- and
- when the lath and patterned polymer board is applied to the wall, the polymer board is in continuous contact with the wall and the polymer board is sandwiched between the wall and the lath.
A lath and patterned polymer board panel for building exteriors, comprising:
- a rectangular patterned polymer board, the pattern selected from the group consisting of dimples, corrugated, and combinations thereof;
- and comprising first and second pairs of adjacent edges;
- and wherein, when installed on a wall, the polymer board;
- is free from mortar holes capable of allowing mortar bridging or mortar droppings through the polymer board and toward the interior of the wall;
- and
- allows for the free passage of moisture through the pattern, thereby avoiding the retention of moisture;
- and
- a rectangular lath panel affixed to the board, the lath panel comprising:
- galvanized slit and expanded steel;
- and
- first and second pairs of adjacent edges;
- and wherein:
- the lath panel and the polymer board arrangement is selected from the group consisting of the first pair of adjacent edges of the lath panel overhang the first pair of adjacent edges of the polymer board, the second pair of polymer board adjacent edges overhang the second pair of lath adjacent edges, and combinations thereof;
- and wherein when the lath and patterned polymer board panel is applied over a weather-resistant barrier, the polymer board is in continuous contact with the weather-resistant barrier and the polymer board is sandwiched between the weather-resistant barrier and the lath.
