DELTA®-FASSADE S

The first mechanically fastened, water-resistive barrier designed to maximize building protection without compromising design aesthetics in open-joint cladding applications.

The best way to protect your open-joint cladding design.

Finalizing your design is only half the battle; you also need to make sure whatever you’re building stays protected. DELTA®-FASSADE S provides water, wind, and UV protection for your open-joint cladding designs with a water-resistive barrier that lets you build with complete confidence.

Weatherproof performance that won’t break down.

The first water-resistive barrier of its kind, DELTA®-FASSADE S is specifically designed for use on demanding open-joint cladding systems, where much of the insulation and substructure is exposed to the elements.

It acts as a durable drainage plane, channelling water from wind-driven rain and snow to the outside of the structure. The watertight membrane helps protect the building enclosure from the damaging effects of moisture infiltration, while its high vapor permeability allows moisture within the cavity to escape.

A water-resistive barrier that helps you stay innovative.

The matte black color of DELTA®-FASSADE S adds depth and dimension while improving the visual appeal of any project. Its UV-stable, water-resistive barrier allows you to maximize building protection without compromising design aesthetics, so you can keep creating open-joint cladding designs knowing your building will be completely protected. DELTA®-FASSADE S maintains its appearance and quality, so you know your building is protected without taking away from the aesthetics of your build.

The leading high-performance solution for the most demanding job.

Backed by years of proven performance and unmatched industry credentials, DELTA®-FASSADE S is known for its superior ability to protect buildings, resist UV rays, maintain the integrity of the insulation underneath, and complement any open-joint cladding design. Through extensive research, trials, and testing, DELTA®-FASSADE S comes out on top as the first UV-resistant, water-resistive barrier solution for open-joint cladding.
