Windows

EEWS designs and engineers the integration of windows and curtainwall units into our systems. Our prefabricated system with integrated windows enables the building to be fully enclosed at the time our panels are erected the field installation of windows and corresponding sealants installed from the building exterior are eliminated, which significantly reduces overall enclosure time. Quality control is greatly improved because our climate-controlled environment allows continuous inspection of the integrity of the moisture, air, and thermal barrier components. EEWS uses many window manufacturers including Skyline, Kawneer, Schuco, and Oldcastle, but any quality manufacturer can be integrated.

FAQ

What is integrated glazing in prefabricated wall panels?

Integrated glazing refers to embedding window systems directly into prefabricated wall panels during the fabrication stage. This method ensures a seamless fit, reduces on-site labor, and enhances the building envelope’s overall thermal and moisture performance.

EEWS provides a range of glazing options to meet diverse architectural and performance needs:
Fixed Glazing Systems: Integrated into panel modules for a sleek appearance.
Operable Windows: Incorporated into the panel layout for functionality.
High-Performance Insulated Glazing Units (IGUs): For energy efficiency and condensation control.
Custom Glazing Treatments: Including frit patterns, tinted glass, and low-E coatings.

Yes, all window and glazing integrations by EEWS undergo rigorous testing, including:
Water Penetration Testing: To ensure watertightness.
Structural Load Testing: To verify durability under various conditions.
Thermal Performance Evaluations: To assess energy efficiency.

ACM panels, profiled metal, and louvers integrate seamlessly with windows for durable, weather-resistant facades.​

EEWS employs a comprehensive quality assurance process:
In-House Engineering: Experienced design teams ensure compatibility with wall panel systems.
Full-Scale Mockups: Used for testing and validation before full production.
Continuous Monitoring: Throughout fabrication to maintain high-quality standards.

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.
