DELTA® PT-lath is a high performance polyethylene meshed membrane which is extruded into a series of studs. The purpose of the studs is to create a continuous air gap behind the waterproof membrane. On the face of the membrane a welded mesh allows plasters and renders to bond efficiently to achieve dry and durable finishes. DELTA® PT-lath is watertight, resistant to high and low temperature extremes, chemically resistant to acids, alkalis, oil and solvents and is approved for use in drinking water applications. It can be used internally or externally on walls and vaults.
