High-Performance Air & Moisture Barriers

DELTA®-TRELA is a vapor permeable underlayment with structured separation and drainage, specifically designed for metal roofs and facades with metal cladding. The underlayment prevents corrosion and moisture accumulation underneath panels, ensuring the longevity of your metal roof.

DELTA®-VENT S-plus is a heavy duty, highly permeable water-resistive barrier and air barrier with an integrated tape. The 3-layer, spun-bonded polypropylene is suitable for all wall applications. High permeability – moisture accumulation within the structure is able to escape via diffusion. Maximizes air tightness, making it ideal for energy-efficient construction.

DELTA®-MULTI BAND 60 is a versatile tape with very strong adhesion. It is highly resistant to aging, and suitable for internal and external use. Composed of pure acrylic adhesive, the product is extremely flexible. Suitable for inside and outside application. Perfectly complements each and every DELTA® product.

DELTA®-FLEXX-BAND is a connecting and sealing tape for internal and external detail elements such as dormer windows, soil pipes, and cables. The product is composed of stretchable bitumen-rubber adhesive on a special non-woven fabric, allowing for great adhesion and stretchability.

DELTA® products control moisture and protect builder investments. DELTA® products prohibit the damaging effects of moisture that reduce overall service life and result in costly repairs.

DELTA® barriers prevent inward air and moisture leakage, stopping mold from entering building spaces while maximizing energy savings. DELTA® products also have high permeability ratings, enabling faster evaporation of incidental water vapor.

As an integral part of the building envelope, DELTA® products contribute to maximum occupant comfort by keeping spaces dry and free from mold. DELTA® products also facilitate pinpoint accuracy of internal temperature and humidity levels.
