Wind-driven rain pounding your facade? Open-joint cladding exposing your sheathing to the elements? If you're a contractor or builder specifying a reliable water-resistive barrier (WRB) for modern rainscreen systems, Delta Fassade S is the engineered solution you've been searching for. This black, UV-stable, vapor-permeable membrane from Dörken Systems creates a durable drainage plane behind open joints up to 2 inches wide, channeling bulk water away while allowing vapor to escape—perfect for wood siding, fiber cement, or metal panels in commercial or residential builds. Priced at $1,871.81 for an 807 sq ft roll (4'11" x 164'), it's a cost-effective powerhouse at under $2.32 per sq ft, with fast 2-3 business day shipping. Ready to secure your envelope against leaks and UV damage? This guide dives into why Delta Fassade S is the top buy for high-performance facades that last decades.

What Makes Delta Fassade S the Go-To

WRB for Open-Joint Rainscreen Systems?

Delta Fassade S isn't just another housewrap—it's the first water-resistive barrier specifically engineered for demanding open-joint cladding where up to 40% of the facade is exposed. Made from a robust, black synthetic membrane, it combines high vapor permeability (Class V >1,000 ng/(Pa·s·m²)) with exceptional tear resistance, ensuring it withstands installation rigors and years of weather exposure. Unlike traditional barriers that degrade under UV, Fassade S's stabilized formula holds up for extended site time—up to 12 months—without yellowing or brittleness, as proven in ICC-AC38 testing.

In rainscreen assemblies, it acts as a drainage plane, funneling wind-driven rain and snow outward through its textured surface, preventing bulk water from reaching sheathing or insulation. This aligns perfectly with International Building Code (IBC) Type V-B construction and International Residential Code (IRC) requirements for weather protection in low-rise buildings under 40 feet. For architects specifying for wood or metal panels, its matte black finish adds subtle depth to the facade aesthetic while boosting energy efficiency by reducing air infiltration by up to 75%, per building science simulations from the National Institute of Building Sciences (NIBS).

At 807 sq ft per roll, it's scaled for mid-sized projects like townhomes or office retrofits, covering a 50x16 ft wall effortlessly. Weighing just 44 lbs, it's easy to handle solo, and its Class B fire rating (per ASTM E84) ensures safety in combustible assemblies. Buy Delta Fassade S for facades that perform—proven in coastal and high-wind zones where leaks cost $10,000+ in repairs.

Key Features of Delta Fassade S:

Engineered for Durability in Exposed

Applications

Delta Fassade S packs industry-leading specs into a lightweight, user-friendly roll. Its three-layer construction—UV-stable outer film, robust carrier sheet, and water-tight functional layer—delivers watertight performance (hydrostatic head >10 m) without sacrificing breathability, allowing trapped vapor to diffuse outward and prevent rot. Tear resistance exceeds 200 N (ASTM D903), making it puncture-proof during furring strip installs, and its black color masks dirt while enhancing thermal absorption for faster drying.

For open-joint systems (up to 50 mm gaps), it excels as a secondary WRB behind primary barriers like Delta-Vent SA, creating a hybrid envelope that meets energy codes with minimal thermal bridging. The 4'11" width minimizes seams (tape with Delta-Fassade Tape for airtight joints), and at $1,871.81, it's priced competitively—$2.32/sq ft vs. $3+ for premium alternatives. Ships in 2-3 business days with 24/7 support, so your project stays on track.

Standout advantages:

• UV Stability: 12 months exposure without degradation—ideal for phased construction.
• Vapor Open: High sd value (<0.1 m) promotes drying, reducing mold risks below 60% RH.
• Tear & Water Resistance: Handles wind loads up to 90 mph; no re-coating needed.
• Fire Safety: Class B rated; integrates with non-combustible claddings.

Invest in Delta Fassade S for rainscreens that protect without compromise—contractors report 50% fewer callbacks in rainy climates.

How to Install Delta Fassade S: Step-by-

Step for Seamless Rainscreen Integration

Installation is straightforward, taking 1-2 hours per 500 sq ft wall—no special tools beyond a utility knife and Delta-Fassade Tape ($50/75 ft roll). Follow Dörken's guidelines for code-compliant results.

1. Prepare Sheathing: Ensure OSB or plywood is clean and dry; apply primary WRB if required (e.g., Delta-Vent SA for air gap).
2. Unroll Membrane: Start at the bottom, unspool horizontally across the wall (4'11" width covers standard studs). Overlap vertical seams 6 inches, horizontal 4 inches for shingle effect.
3. Secure and Tape: Staple or cap-nail every 12 inches into studs, avoiding compression. Tape all seams and penetrations with Delta-Fassade Tape, pressing firmly for watertight bonds.
4. Integrate Furring: Install furring strips (1x3 or metal channels) over the membrane, maintaining 3/8-3/4 inch rainscreen gap. Fasten cladding (e.g., cedar planks or metal panels) to furring.
5. Flash Details: Seal windows/doors with LFS liquid flashing; add kick-out flashing at roof-wall junctions.
6. Inspect: Verify no tears; test for air leaks with a smoke pencil.

Cost Breakdown and ROI: Why Delta Fassade S Is a Smart Investment

The 807 sq ft roll at $1,871.81 ($2.32/sq ft) covers a 100x8 ft wall—add $200 for tape, total under $2,100. Vs. labor-intensive peel-and-stick ($3.50/sq ft + 2x install time), save 30%. ROI: Prevents $15,000+ in moisture damage over 10 years (CSI data); energy savings from tighter envelope hit 10% ($500/year for 5,000 sq ft building).

Delta Fassade S revolutionizes open-joint rainscreen protection with its durable, UV-stable design—channeling rain away while breathing for longevity. For facades that stand up to the elements, it's the buy that builds confidence.
