DELTA Premium Water Resistive Barriers
PREMIUM-QUALITÄT

DELTA®-FOXX

The Water-Resistive Barrier with the highest vapor permeability on the market today. This premium watertight WRB is ideal for use under a wide variety of cladding materials.

ICC-ES Evaluation Report (AC38)

ICC ESR-2932

Properties

DELTA®-FOXX is watertight and will thus resist the passage of bulk (liquid) water from wind-driven rain and snow. It will act as a drainage plane behind the cladding to channel water to the outside and help protect the building enclosure from damaging effects of moisture infiltration.

The extremely high vapor permeability of this WRB allows any moisture within the building enclosure to escape swiftly by diffusion. DELTA®-FOXX is Class A fire-rated, and its vapor permeable and waterproof qualities are unaffected by surfactants.
See DOWNLOADS tab for the NFPA 285 Compliant Wall Assemblies document.

Material

Special, highly tear-resistant Polyester non-woven substrate with a vapor permeable but watertight acrylic dispersion coating.

Application

DELTA®-FOXX is very light-weight, making installation fast, easy, and reliable. The membranes do not distort, buckle or flap. It can be easily lined up and unrolled. Its anti-glare coating prevents annoying reflections even in extreme sunlight.

This technologically advanced membrane is extremely tear and scuff resistant, which helps it to withstand the rigors of job sites, as well as tough wind and weather conditions.
