Air Vapor Barrier
The Air Vapor Barrier (AVB) is a critical component of our wall panel systems responsible for moisture control. It is integrated early in the design and fabrication process to ensure that our enclosures meet the highest standards for vapor management, air infiltration control, and thermal performance. EEWS’s meticulous design and installation of this component helps our systems achieve optimal efficiency and continued protection of the building’s structure and interior environments over time. Different styles and manufacturers of AVB areutilized depending on the specific system and project needs, including 3M, Delta Facade, Dörken, Vapro Shield, and Henry Blue Skin.

Air Vapor Barrier (AVB) Integration
The Air Vapor Barrier (AVB) is a critical component of our wall panel systems. Integrated early in the design and fabrication process, the AVB ensures that our enclosures meet the highest standards for moisture management, air infiltration control, and thermal performance. A properly designed and installed AVB is essential to achieving optimal moisture efficiency, protecting both the building structure and interior environments over the long term.
Importance of Moisture Management
Moisture infiltration can compromise the durability, energy performance, and health of a building if not properly addressed. Our AVB systems are engineered to manage vapor diffusion and prevent uncontrolled air and water penetration. By controlling the movement of moisture through the building envelope, we minimize the risk of condensation, mold growth, material deterioration, and energy loss. The AVB forms a continuous barrier behind the wall panel system, creating a robust line of defense against environmental forces. This continuous protection significantly extends the life of the structure while ensuring occupant comfort.
Benefits Of An Integrated AVB System
Integrating the Air Vapor Barrier within our panel systems offers numerous advantages:
- Enhanced Moisture Protection: Reduces the risk of water intrusion and condensation-related issues.
- Improved Energy Efficiency: Controls air leakage, reducing HVAC loads and operational energy costs.
- Greater Durability: Protects structural elements from moisture damage, extending building lifespan.
- Consistent Quality: Factory-controlled or tightly managed field applications ensure reliable performance.
- Streamlined Installation: Simplifies coordination by integrating AVB within the prefabrication process, reducing time and complexity on-site.
Testing & Verification
At EEWS, quality assurance is central to everything we deliver. All AVB systems are subject to rigorous inspections and testing to ensure compliance with project specifications and applicable building codes. Testing may include:
- Air Barrier Performance Testing (ASTM E2357)
- Water Penetration Resistance Testing (ASTM E331)
- Blower Door Testing for overall building tightness

Maximizing The benefits Of Prefabrication
Design Assist
Our collaborative process unites one experienced team from design through installation. In-house Revit-certified designers ensure every detail is carefully planned and executed. Early alignment on goals and continuous design and budget feedback keep projects on track. This streamlined approach eliminates inefficiencies and delivers reliable, high-quality results.
Safer Job Site
Our panelized enclosure system reduces on-site labor and shortens the project timeline, cutting labor costs. Pre-engineered and assembled off-site, it eliminates material storage, site congestion, and waste. Fewer trades are needed on-site, creating a cleaner, safer work environment. This streamlined process also lowers the risk of accidents and boosts site efficiency.
Quality Assurance
Our panelized systems provide superior thermal, moisture, and air performance through a continuous, high-quality enclosure. Assembled in a controlled facility, components like AVB, windows, and louvers are installed with precision. A single expert team handles multiple trades, reducing gaps and delays. This process also simplifies inspections and ensures consistent quality.
Building Enclosure Speed
Prefabricated panel systems greatly speed up the building enclosure process. Off-site fabrication in a controlled environment allows for faster dry-in and earlier interior work. This reduces weather delays and shortens the overall schedule. It’s an ideal solution for projects with tight timelines or phased occupancy.
Coordinated Engineered Interfaces Solutions
Our system features fully coordinated, engineered interfaces for seamless integration of all enclosure components. Key details are resolved during design and fabrication, avoiding on-site conflicts. This approach minimizes field adjustments and ensures consistent quality. The result is a unified, high-performing building envelope from day one.
Logistics
Prefabricated enclosure systems streamline logistics by reducing the volume of material delivered to and stored on-site. With just-in-time delivery and panels arriving in sequence, site congestion, waste, and handling are minimized. This controlled flow of materials supports cleaner, safer job sites and simplifies coordination among trades. The result is a more efficient, organized construction process that aligns with modern lean building practices.
Thermal Performance
When design allows, increasing opaque wall areas with prefabricated systems can greatly improve thermal performance. Fewer unitized joints enhance energy efficiency and air-tightness. These systems also offer broad cladding flexibility, giving architects more design freedom. In this case, the prefabricated enclosure is over four times more energy efficient than a traditional glass curtain wall.
