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.
DELTA®-FASSADE S is the only UV stable water-resistive barrier that is tested to and has passed ICC-AC38. See our ESR-2932, the only true evidence of compliance.
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 A fire-rated. Its performance is unaffected by surfactants.
