Air Vapor Barrier

Air Vapor Barrier

The Air Vapor Barrier (AVB), a critical component of our systems, is analyzed early in the design assist process to provide the highest performance for moisture and air management and continued protection of the building’s skin and interior environment over time.

Different styles and manufacturers of AVB are utilized depending on specific project requirements. Our manufacturers include but are not limited to 3M, Tremco, Carlisle, and Henry Blue Skin.

FAQ

What is an Air Vapor Barrier (AVB) in building construction?

An Air Vapor Barrier (AVB) is a critical component in building envelopes that controls air and moisture infiltration. It helps maintain energy efficiency and prevents issues like mold and structural damage.

Integrating AVB into wall panel systems ensures continuous protection against moisture and air leaks, enhancing the building’s durability and thermal performance.

Common AVB materials include sheet-applied membranes, fluid-applied coatings, and self-adhered membranes. The choice depends on project-specific requirements and environmental conditions.

By preventing uncontrolled air leakage, AVB reduces HVAC loads, leading to lower energy consumption and improved indoor comfort.

High-performance AVB materials offer superior air and moisture control, durability, and compatibility with different building components, ensuring long-term performance.

The EEWS Difference

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.
