50+ Years of
Excellence & Expertise
In the early 1970s, Eastern Exterior Wall Systems (EEWS) pioneered the prefabrication of exterior walls for large buildings. Since then, more than 15 million square feet of our prefabricated systems mark city landscapes from Boston to Charlotte and west to Chicago.
Each of EEWS’s projects are custom designed, manufactured and installed to the architect’s vision. Our systems include the wall framing outward to the finished cladding in either ventilated rainscreen or barrier performance models expertly integrated into one product.
Our systems are fabricated in 300,000 square feet of new climate-controlled facilities in Pennsylvania and New York.

Learn MoreInsulation & Girts
EEWS’s systems are engineered with internal girts to provide proper support for the outboard cladding materials. Girts range from galvanized, to thermally neutral fiberglass, to aluminum, to stainless steel. We use various types of insulation without our systems, including Polyisocyanurate Boards, Mineral Wool, and Rigid Foam.

Extrusions and Gaskets
We utilize a dry gasket system in our wall panel assemblies to deliver superior weather resistance, improved safety, and faster installation timelines. Unlike traditional wet sealant systems, *ending to be edited*
Learn MoreFraming
Framing serves as the structural backbone of our wall panel systems. We engineer and fabricate the framing that provides the necessary support for the exterior cladding and other panel components. Each frame is precisely designed to meet the building’s structural, thermal, and performance requirements.
Learn MoreAVB
Integrated early in the design and fabrication process, the Air Vapor Barrier (AVB) ensures that our enclosures meet the highest standards for moisture management, air infiltration control, and thermal performance.

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.
Fabrication Process
Prefabrication involves designing and manufacturing high-performance Exterior Wall Systems in a controlled environment before they reach the job site. These systems integrate components like structural framing, insulation, and cladding into complete, ready-to-install Exterior Wall Panels. By building off-site, Exterior Wall Systems significantly reduce installation time, improve quality, and minimize safety risks. Each of our precision-engineered Exterior Wall Panels is fabricated to exact specifications, eliminating the inconsistencies of on-site construction. Through early planning and coordinated engineering, Exterior Wall Systems simplify complex construction workflows and accelerate building enclosure. With integrated joints and finishes, Exterior Wall Panels arrive prefinished and require minimal site work. The durability and performance of our Exterior Wall Systems enhance energy efficiency and long-term value. Meanwhile, the clean installation of Exterior Wall Panels supports safer, more organized jobsites. Built under strict quality control, Exterior Wall Systems eliminate weather-related delays and reduce rework. Thanks to their factory-level precision, Exterior Wall Panels deliver consistent results across projects. By consolidating trades and components, Exterior Wall Systems streamline scheduling and reduce coordination issues. The sleek, modern look of our Exterior Wall Panels also elevates architectural aesthetics while meeting performance demands.

Installation Process
Our innovative Exterior Wall Systems are fully fabricated and pre-assembled to ensure speed, accuracy, and reduced on-site labor. Each of our Exterior Wall Panels is precision-manufactured in a controlled environment, enabling faster installation with minimal field adjustments. By using Exterior Wall Systems, projects benefit from improved safety, less scaffolding, and fewer workers at height. The integration of pre-finished Exterior Wall Panels also accelerates building enclosure, allowing interior work to start sooner. With our efficient Exterior Wall Systems, jobsite coordination is smoother and more predictable. Additionally, the consistent quality of our Exterior Wall Panels enhances long-term durability and aesthetic appeal. The early dry-in capability of our Exterior Wall Systems protects interior trades from weather delays. Meanwhile, streamlined Exterior Wall Panel installation shortens construction timelines and lowers costs. Our approach to delivering complete Exterior Wall Systems helps reduce project complexity and overall risk. Combining function and form, our Exterior Wall Panels offer a high-performance envelope solution for commercial and institutional buildings. Utilizing modern Exterior Wall Systems leads to faster schedules and improved build quality. With our factory-built Exterior Wall Panels, you get a cleaner, safer, and more efficient construction process.

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.
