Custom Aluminum Sliding Windows for the UMBC Stadium Press Box
PROJECT SCOPE
Type: Facilities - Sports Complex
Location: 5523 Research Park Dr., Lansdowne, Baltimore, MD 21227
Age of Structure: Renovation
Window System: V-4200 Sliding System
Installer: Ridgeview Glass Inc.
A stadium press box depends on its connection to the field. Broad views help staff follow the action, while operable windows provide flexibility for broadcasting, ventilation, and event operations. At UMBC Stadium, Vetrina manufactured custom aluminum sliding windows that bring these requirements together within a clean, coordinated exterior.
The project demonstrates how precise fabrication, thoughtful opening configurations, and carefully specified materials can support a specialized university facility.
Windows Designed Around Stadium Operations
Located at the University of Maryland, Baltimore County’s campus in Baltimore, Maryland, UMBC Stadium underwent a major renovation between 2021 and 2023. The improvements included a new press box with multiple broadcast booths and a VIP area, alongside upgraded seating and spectator access. UMBC’s stadium overview documents the completed renovation.
Positioned above the bleachers, the press box overlooks the playing field and surrounding track. Its long, horizontal form places the windows at the center of both the architecture and the building’s purpose.
Vetrina’s window package, documented in shop drawings prepared for Ridgeview Glass, comprises seven four-panel sliding assemblies in five custom sizes. The largest frames span 14 feet, providing generous glazed openings within the building’s metal-clad exterior.
Vetrina V-4200 Sliding Windows: Broad Views and Practical Operation
UMBC selected Vetrina’s V-4200 sliding system for its stadium press box. This versatile aluminum system accommodates multiple sash arrangements and thermally broken profiles.
For UMBC, each assembly uses four glazed panels with two operating center sashes. These sashes slide apart toward the sides, creating a broad central opening without a permanent center mullion dividing the open space.
That configuration provides several advantages for a press box:
Direct views through the open center. Retracting the operating sashes removes glass from the central viewing area, creating a useful opening for observation or camera positioning as needed.
Clearance around workstations. Horizontal sliding operation keeps sash movement within the frame, preserving space for desks, equipment, and circulation.
Adjustable ventilation. Staff can vary the opening to introduce outdoor air when conditions and operations permit.
A consistent exterior. The same four-panel arrangement repeats across different opening sizes, giving the façade a coherent appearance.
The project photographs show this flexibility clearly: closed assemblies provide expansive glazed views, while open assemblies create a direct connection between the interior and the stadium surroundings.
Five Custom Sizes, One Coordinated Window Package
The window schedule shows the precision required to manufacture a specialized structure. Although the assemblies share a common operating layout, their dimensions respond to individual openings.
| Window Designation | Quantity | Overall Frame Width × Height |
|---|---|---|
| COR-4200 Slider #1 | 1 | 168″ × 70⅛″ |
| COR-4200 Slider #2 | 2 | 168″ × 70¾″ |
| COR-4200 Slider #3 | 2 | 167¼″ × 70¾″ |
| COR-4200 Slider #4 | 1 | 120″ × 70¾″ |
| COR-4200 Slider #5 | 1 | 118⅝″ × 70¾″ |
| Total | 7 | Five custom sizes |
Small dimensional differences matter. Two assemblies can look nearly identical from the stands but require different frame widths, sash dimensions, and glass sizes.
For architects and glazing contractors, this capability matters: Vetrina can maintain a consistent architectural design while manufacturing assemblies to the dimensions documented for each opening.
Insulated Low-E Glazing for Daylight and Comfort
Large windows contribute daylight and visibility, but their glazing also influences comfort inside an occupied press box.
The UMBC shop drawings specify a 1-inch insulated glass unit comprising:
¼-inch clear tempered glass with an SN68 low-E coating.
A ½-inch argon-filled cavity.
¼-inch clear tempered interior glass.
The specification permits an equivalent glazing product.
This combination addresses several needs within the structure. The low-E coating helps control heat transfer and solar gain while retaining a clear appearance suited to field observation. The argon-filled cavity improves the insulating function of the glass assembly, and the thermally broken aluminum profiles reduce heat conduction through the framing.
Guardian describes SN 68 glass as combining high visible-light transmission with solar control and a neutral appearance. Those characteristics suit a building where the view is essential and occupants work close to large glazed openings.
The result is a specification that considers the press box as an occupied workspace, with daylight, visibility, and thermal comfort addressed together.
Pearl Dark Gray Aluminum Frames for an Exposed Setting
The drawings call for RAL-9023M Pearl Dark Gray frames, black hardware, and powder coating to AAMA 2605 requirements.
The gray finish complements the horizontal metal cladding, allowing the windows to read as integrated parts of the building. Their rectangular proportions reinforce the press box’s long profile, while the darker framing defines each glazed opening.
The coating requirement also serves a practical purpose. AAMA 2605 addresses demanding exterior coating performance, including resistance to weathering, fading, and chalking. PPG’s explanation of AAMA 2605 outlines these durability requirements.
For university facilities teams, specifying the finish alongside the window system helps account for appearance and long-term exterior exposure from the outset.
Detailed Shop Drawings Support Construction Coordination
Vetrina’s contribution extends into the documentation needed to coordinate fabrication and installation.
The UMBC drawing set includes individual window elevations, frame and rough-opening dimensions, sash and glass sizes, operating directions, and detailed head, sill, jamb, interlock, and center-meeting sections. It also identifies field-installed perimeter seals, backer rod, shims, and fasteners as work by others.
This level of detail gives the project team a defined basis for reviewing how the windows fit, operate, and connect to the surrounding construction. For glazing contractors and general contractors, it supports coordination between the manufactured assemblies and the building envelope.
At UMBC Stadium, the capability is visible in both the drawings and the photographs: large custom windows, repeatable detailing, and opening configurations suited to the building’s daily use.
Plan Your Next Institutional Window Project With Vetrina
Press boxes, athletic facilities, and university buildings demand windows that respond to specific operational needs. Opening size, sightlines, sash movement, glazing, finish, and installation interfaces all influence the final result.
Vetrina’s UMBC Stadium project demonstrates the ability to bring those decisions into a coordinated custom aluminum window package.
