Durable and long-lasting, Conwed plastic lath is designed to replace traditional, more expensive metal lath used in flooring (especially for tile underlayment). Unlike metal lath, plastic lath doesn’t have sharp corners and edges that will cut or tear. Made from a polyolefin base, plastic lath is easily trimmed to fit into any shaped space and won’t rust—ever. Conwed plastic lath works with electric and hot water radiant floor heating systems.
