Product Summary
For residential solutions, the right air and moisture barrier is one of the most critical components of the building envelope. Traditional barriers are no longer good enough. Whether you need moisture management for your walls, roof or foundation, DELTA® has the high-performance product to meet your specific needs.
As commercial buildings become more energy efficient and strive for higher LEED qualifications, air and moisture control in the building envelope is becoming more important. DELTA® has the technical support and products to enable architects to specify the best solution for each building.
Construction and Materials
Dorken Delta Products offers a range of innovative solutions designed to enhance the performance and longevity of building envelopes. Their products fall under the categories of Weatherization & Flashing, including Air & Water Barriers, Rainscreens, and Rainscreen Systems.
The construction of these products typically involves multi-layer materials engineered for optimal breathability, water resistance, and air control. These are not simple films but rather sophisticated assemblies designed to manage moisture and air movement effectively within wall systems.
Key materials commonly found in Dorken Delta products include:
- High-Density Polyethylene (HDPE) or Polypropylene: These form the core of many membranes, providing a robust and durable foundation for air and water barrier functions.
- Non-woven Fabrics: Often made from polypropylene, these layers contribute to the product's tear resistance, impact strength, and can provide a textured surface for drainage and ventilation in rainscreen applications.
- Microporous Membranes: These advanced materials are designed to allow water vapor to escape from the building while preventing liquid water and air from penetrating the wall cavity.
- Adhesives and Coatings: Specialized coatings and adhesives are used to ensure airtightness and securement, particularly in integrated systems where membranes are designed to be sealed together.
- Perforations or Grooves: In rainscreen products, the construction often includes specifically engineered perforations or grooves on the surface to create an air gap and facilitate drainage behind the cladding.
The integration of these materials allows Dorken Delta products to function as:
- Air & Water Barriers: These products are critical for preventing uncontrolled air infiltration and exfiltration, which can lead to significant energy loss and moisture-related building damage. They also act as a secondary defense against bulk water penetration, protecting the building structure from the elements.
- Rainscreens: Dorken Delta's rainscreen products create a ventilated and drained cavity behind the exterior cladding. This gap allows any water that may penetrate the cladding to drain freely and any trapped moisture to dry out, significantly reducing the risk of rot, mold, and material degradation.
- Rainscreen Systems: These are comprehensive solutions that often include the rainscreen membrane, accessories for sealing and detailing, and sometimes even integrated components designed to simplify installation and enhance performance. The system approach ensures that all parts work together harmoniously to create a complete and effective weather protection solution.
The design of Dorken Delta products emphasizes ease of installation, durability in challenging construction environments, and long-term performance, contributing to healthier, more energy-efficient, and durable buildings.

Product Features and Benefits
Air & Water Barrier Systems
Delta provides high-performance membranes and tapes engineered to create a continuous, airtight, and watertight seal within the building envelope. These systems are crucial for preventing uncontrolled air movement and the ingress of bulk water, which can lead to significant structural damage and occupant discomfort.
- High Water Vapor Permeability: Allows moisture trapped within the wall assembly to escape, preventing condensation buildup and protecting insulation from becoming damp.
- Excellent Air Tightness: Significantly reduces air leakage, contributing to improved indoor air quality and substantial energy savings by minimizing heat loss or gain.
- Durability and Robustness: Designed to withstand the rigors of construction and long-term exposure to environmental conditions.
- Easy Installation: Many Delta membranes and tapes are designed for straightforward application, reducing labor time and costs on site.
- Compatibility: Works effectively with a wide range of building materials and insulation types.
Rainscreen Technology
Delta's rainscreen solutions are designed to create a ventilated drainage plane behind the exterior cladding. This gap allows for the unimpeded flow of water away from the building structure and promotes drying through ventilation, a critical aspect of modern building science.
- Effective Water Drainage: Channels bulk water away from the facade, preventing it from reaching the weather-resistive barrier and structural components.
- Enhanced Drying: The ventilated cavity promotes rapid drying of the facade, reducing the risk of moisture-related deterioration such as rot, mold, and corrosion.
- Pressure Moderation: Helps to equalize air pressure between the exterior and the cavity, reducing the driving force for water penetration during wind-driven rain events.
- Protection of Building Materials: Extends the life of cladding, sheathing, and insulation by keeping them dry and protected from moisture damage.
- Improved Thermal Performance: By keeping insulation dry, the overall thermal performance of the wall assembly is maintained and optimized.
Rainscreen Systems
Delta offers complete integrated rainscreen systems that combine their advanced membranes and drainage components. These systems are meticulously designed to work in harmony, providing a simplified and highly effective solution for creating a durable and breathable building facade.
- Engineered for Performance: Each component within the system is designed to complement the others, ensuring optimal performance of the entire rainscreen assembly.
- Comprehensive Protection: Provides a multi-layered defense against water ingress, air leakage, and moisture buildup.
- Simplified Specification and Installation: Offers a curated solution, reducing complexity in material selection and construction processes.
- Long-Term Building Health: Contributes to a healthy indoor environment and a durable, long-lasting building structure by effectively managing moisture.
- Aesthetic Flexibility: Facilitates the use of a wide variety of cladding materials while ensuring their performance and longevity.
Options-Styles
Delta offers a range of high-performance weatherization and flashing solutions designed to enhance building envelope integrity. Their product lines focus on air and water barrier systems, rainscreen technologies, and comprehensive rainscreen systems.
Air & Water Barrier Systems
Delta's air and water barrier systems are engineered to prevent uncontrolled air leakage and the ingress of liquid water, crucial for energy efficiency and moisture control. These membranes create a continuous barrier, protecting the building structure from the elements and improving indoor air quality.
Rainscreen Technology
The brand provides advanced rainscreen solutions that establish a ventilated airspace between the cladding and the weather-resistive barrier. This airspace allows for the drainage of bulk water and the escape of incidental moisture vapor, significantly reducing the risk of interstitial condensation and material degradation.
Rainscreen Systems
Delta's integrated rainscreen systems offer a complete approach to building envelope performance. These systems often include:
- Primary Weather-Resistive Barrier: Forms the initial line of defense against water and air infiltration.
- Drainage and Ventilation Components: Features designed to facilitate water drainage and air circulation within the rainscreen cavity.
