Described as ‘the original’ waterproof membrane system, Delta-PT and Delta-Lath will insulate and isolate damp and contaminated walls, vaults and basements. Delta-PT is a special high performance polyethylene membrane which is extruded into a series of studs that create a continuous air gap behind the waterproof membrane. On the face of the membrane a welded mesh which allows plasters and renders to bond efficiently to achieve dry and durable finishes. Delta-PT is watertight, resistant to high and low temperatures, chemically resistant to acids, alkalis, oil and solvents and is approved for use in drinking water applications. The 8mm stud provides a continuous air gap to isolate the damp wall from the new plaster, and to allow ventilation of the wall for permanent dampness control.
