Specialty & Functional Glass

Glass isn’t just a design choice. It’s a performance material. Our specialty & functional slass systems are engineered to deliver more than transparency: they control light, temperature, safety, and energy efficiency at every level of the building envelope. Each installation is designed to meet the specific demands of modern architecture where sustainability, security, and sophistication intersect.

From high-performance office towers and retail environments to healthcare, education, and transportation hubs, our glass solutions are tailored for durability, comfort, and compliance without sacrificing aesthetic excellence.

We can install the following:

  • Insulated glass units (IGUs)
  • Low-E energy-efficient glass
  • UV-control and solar-reflective glass
  • Smart and dynamic tint glass
  • Thermal break glazing systems
  • One-way vision glass (reflective)
  • Anti-reflective display glass
  • Safety-laminated security glass

Each system serves a distinct function. Insulated glass units and thermal break glazing improve energy retention and condensation resistance. Low-E and solar-reflective coatings manage heat gain and glare, optimizing building performance through all seasons. For advanced light and privacy control, smart tint glass adjusts dynamically to environmental conditions, while one-way and anti-reflective options enhance visibility and display precision.

When safety is paramount, laminated security glazing delivers impact protection and forced-entry resistance without compromising design intent. All Top Door systems are engineered for code compliance, acoustic performance, and integration with curtain walls, storefronts, and façade assemblies.

Because the right glass doesn’t just reveal. It protects, performs, and perfects.
With Top Door, every pane has a purpose.
