Marquee-Lok Panel: A Versatile Option for Soffit, Fascia, and Walls

When it comes to building design, the panels that frame, finish, and connect the exterior often play just as important a role as the primary roof or wall systems. Soffits, fascia, and accent wall panels contribute to both appearance and long-term durability, especially on commercial and institutional buildings designed for extended service life.

Marquee-Lok is a concealed fastener metal panel designed to support these building envelope needs. It is most commonly used as a soffit and fascia panel, with the added capability to be used as a wall panel. This versatility makes Marquee-Lok a useful option for designers and specifiers looking to carry a consistent panel profile across multiple areas of a building.

What Is Marquee-Lok?

Marquee-Lok is a concealed fastener metal panel designed to complement McElroy Metal roof and wall systems. Its profile allows for clean, continuous lines while hiding attachment points, resulting in a refined appearance across exposed building elements.

The panel is most frequently specified for soffit and fascia applications, where visual consistency and clean detailing are important. It is also suitable for vertical wall applications, allowing designers to extend the same panel aesthetic beyond the roof edge and into the building façade.

Primary Applications: Soffit and Fascia

Marquee-Lok is widely used as a soffit and fascia panel because it provides a finished, uniform appearance while supporting proper detailing at roof edges and overhangs.

In soffit applications, the concealed fastener design helps create smooth visual transitions beneath rooflines, canopies, and overhangs. In fascia applications, the panel provides a clean edge detail that complements adjacent roof and wall systems without introducing exposed fasteners.

These applications are especially common on commercial buildings, institutional and municipal facilities, educational campuses, healthcare environments, and office and mixed-use developments. In these settings, soffit and fascia panels are often highly visible and expected to perform reliably with minimal maintenance over time.

Wall Panel Capability and Design Continuity

In addition to its use in soffit and fascia, Marquee-Lok can be used as a wall panel.

One of the advantages of Marquee-Lok is its ability to help designers maintain visual consistency across different parts of a building. By using the same panel profile for soffits, fascia, and walls, projects can achieve a cohesive appearance without relying on multiple unrelated products.

This approach is particularly effective on buildings where transitions are highly visible, such as entry canopies, overhangs and porte-cochères, architectural accents, and mixed-use façades. Rather than standing out as separate components, these elements work together visually when designed with compatible panels.

Performance Is Still About the System

As with any metal panel application, performance does not rest on the panel profile alone. Marquee-Lok's success depends on how it is integrated into the overall building.

Factors that influence long-term performance include proper substrate and attachment, accurate detailing at transitions and terminations, coordination with adjacent systems, and overall installation quality. In many cases, long-term issues are traced back to detailing or installation decisions rather than the panel itself. This is especially true for soffit, fascia, and wall applications, where water management and airflow must be carefully considered.

Material and Finish Considerations

Marquee-Lok panels are manufactured from 22 GA and 24 GA Galvalume®, as outlined in the product specifications. Using a consistent substrate helps ensure the panel maintains the same construction and appearance, whether it's installed as a soffit, fascia, or wall panel.

The panel is finished with a Kynar 500® (PVDF) coating. This factory-applied coating is commonly referenced across McElroy Metal product specifications and provides a uniform finish on visible exterior surfaces.

Together, these material and finish details define how the Marquee-Lok panel is constructed and help maintain a cohesive look across soffit, fascia, and wall installations.

Installation Quality Matters

Although Marquee-Lok is a concealed fastener panel, installation quality remains critical. Proper alignment, fastening, and detailing all contribute to both appearance and performance.

Panels used in soffit, fascia, and wall applications must be installed in accordance with manufacturer guidance and project specifications. When installed correctly, Marquee-Lok supports durable, low-maintenance exterior finishes. When shortcuts are taken, even a well-designed panel cannot compensate.

Where Marquee-Lok Fits Best

Marquee-Lok is best suited for projects where a clean, concealed fastener appearance is desired, soffit and fascia detailing are highly visible, wall accents or vertical panel applications are needed, and design continuity across the exterior is important. Because Marquee-Lok is used at soffits, fascia, and walls, it helps create clean, finished transitions across the building exterior.

Final Thoughts

Marquee-Lok is not limited to a single application, nor is it intended to be a universal solution. Its strength lies in its flexibility, supporting soffit, fascia, and wall applications while maintaining a clean, coordinated appearance across the entire building.

When thoughtfully specified and properly installed, Marquee-Lok can be a valuable component of commercial and institutional projects designed for long-term performance. Working with experienced professionals and manufacturers like McElroy Metal helps ensure the panel is used in a way that aligns with both design intent and real-world conditions.
