Maximum Protection for Open-Joint Cladding Systems
DELTA-FASSADE 20 PLUS is the ultimate professional solution for rear-ventilated facades with open joints. Formulated with a highly tear-resistant polyester cloth and a specialized UV-resistant coating, this membrane guarantees long-term durability behind open joints up to 20 mm wide (covering up to 20% of the total surface area).
Key Features & Technical Advantages:
- Permanent UV Stability: Engineered to withstand prolonged, direct exposure to sunlight through open joints without degrading.
- Integrated Self-Adhesive Edges: Features the "PLUS" dual adhesive strip system for an instant, wind-tight, and secure seal at all overlaps, eliminating thermal bridging.
- High Vapor Permeability: With an exceptional Sd-value of approx. 0.02 m, it allows interior moisture to escape freely, preventing mold growth and rot within the structure.
- Extreme Weatherproof Barrier: Acts as a tough shield against driving rain, wind, and drifting snow while keeping external insulation perfectly dry.
Ideal Applications:
Perfect for modern commercial and residential architectures utilizing open-joint timber cladding, composite panels, metal facades, and open-joint stone rain-screens.
