High density polyethylene
|Roll dimensions (w x l)||
DELTA® PT is a high-performance polyethylene membrane that has been specially designed with damp control in mind.
It is used to insulates and isolate damp and contaminated walls, vaults, and basements.
DELTA® PT is manufactured with 8mm extruded studs that create a continuous air gap. This results in a watertight, temperature and chemical-resistant seal.
The 8mm stud design of DELTA® PT provides a continuous air gap which serves two purposes. It isolates the damp wall from new plaster and decorative finishes, and it allows ventilation of the wall for permanent damp control.
Ventilation can be achieved by using the DELTA® PT profile or the air gap can be vented externally via passive air vents.
On the face of the membrane, a welded mesh allows plasters and renders to bond efficiently to achieve dry and durable finishes.
DELTA® PT 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.
