The Easiest Way to Protect Open-Joint Cladding Designs from UV Damage and Moisture


At Dörken, we take pride in responding to unique industry needs with superior-performing building solutions.

When working with open-joint cladding designs, building professionals must choose between design integrity and protection. With no signs of the trend slowing down, this industry-wide dilemma inspired us to develop a better air- and water-resistive barrier (WRB) that would finally give building professionals both.

Certified Passive House Consultant and experienced technical services manager Krzysztof Apriasz explains some of the innovative features and the simple installation of our WRB for open-joint cladding systems: DELTA®-FASSADE SA.

About DELTA®-FASSADE SA air- and water-resistive barrier

Offered alongside DELTA®-FASSADE S, DELTA®-FASSADE SA is a four-layer, self-adhered WRB with industry-leading UV stability to ensure product performance and longevity.

Its two outer layers are made of a high-strength, spun-bonded polypropylene (PP) fabric and are thermally bonded to a highly vapor permeable, watertight polymeric middle layer, offering a hybrid between the industry-proven DELTA®-VENT SA and DELTA®-FASSADE S.

On top of all this, the product features an innovative UV-resistant acrylic coating that is proven to provide true UV protection.

The innovation of two high-performance building envelope products designed to protect rainscreen cladding has afforded us the opportunity to work on some truly inspirational buildings across North America.
