DELTA®-FASSADE S

The extreme UV resistance of this water-resistive barrier makes it particularly suitable for use in open joint cladding systems. The watertight membrane is highly vapor permeable and extremely tear resistant

Its excellent stability against ultra violet light means no doubling up of the membrane and no sacrificial layers. DELTA®-FASSADE S provides sustainable moisture protection behind open joint claddings for many years of service.

ICC ESR-2932

Properties

DELTA®-FASSADE S, highly stabilized against damage from UV exposure, is designed for use in cladding systems that have open joints of up to 2” (50 mm) wide which expose up to 40 % of the entire facade surface. It acts as a durable drainage plane, channeling bulk (liquid) water from wind-driven rain and snow to the outside of the structure. The watertight membrane helps protect the building enclosure from damaging effects of moisture infiltration. Its high vapor permeability allows moisture within the cavity to escape swiftly. DELTA®-FASSADE S is Class B fire-rated. Its performance is unaffected by surfactants.

Material

Highly tear-resistant polyester substrate with a special, highly UV-stabilized acrylic coating

Application

DELTA®-FASSADE S is very light-weight and tear-resistant, making installation fast, easy, and reliable. This technologically advanced membrane withstands the rigors of jobsites, as well as tough wind and weather.
