Exterior Envelope Enhancements

We elevate the building envelope into an art form. Our exterior envelope enhancements strengthen the connection between structure and design, integrating glass, metal, and silicone systems that deliver superior aesthetics, performance, and protection against the elements. Every component we install works in harmony to enhance energy efficiency, weather resistance, and visual continuity across a building’s exterior.

From corporate towers and educational facilities to mixed-use developments and institutional projects, we partner with architects and engineers to design façades that perform as beautifully as they look.

Our capabilities include spandrel glass panels, vision-to-spandrel transitions, window wall systems, glazed roof structures, structural silicone glazing (SSG), and stick-built and unitized façade systems.

Each system is engineered for precision to balance thermal performance, structural integrity, and design intent. Our spandrel and vision glass assemblies achieve seamless transitions across elevations, while window wall systems and unitized façades streamline installation and improve air, water, and thermal resistance. Glazed roof structures and SSG systems deliver uninterrupted sightlines and airtight durability, giving architects the freedom to design without compromise.

Top Door ensures every envelope enhancement meets code compliance, energy efficiency, and sustainability standards, backed by expert installation and quality assurance.

Because true performance isn’t just about keeping the weather out. It’s about letting innovation shine through.
