What is a Glazing System?

October 26, 2023

In commercial architecture, glazing systems are a fundamental element in building design. Glazing systems offer a seamless integration of glass within aluminum or steel framing systems, transforming the way we experience and interact with buildings. Glazing systems incorporate a wide range of techniques, materials, and technologies that enable the incorporation of glass elements into the design of structures. The primary purpose of glazing systems is to achieve a balance between transparency, natural light, energy efficiency, thermal comfort, and visual appeal all while keeping occupants inside the building comfortable. At Egan, our InterClad team are the experts in storefront, curtain wall, window wall, and glass and glazing. When it comes to the design, engineering, and installation of these systems, Egan will be there to assist you. 


Glazing systems rely on glass panels for transparency and natural light transmission that are supported 

by sturdy frameworks and sealed to ensure a weatherproof installation. There are various thermal features in these systems that enhance energy efficiency. Together, these elements create visually appealing and sustainable building envelopes.

  • GLASS PANELS: At the core of any glazing system lies a glass panel. It is the primary component that allows for transparency and facilitates the transmission of natural light into a building’s interior space. Glass panels come in various types, including heat strengthened glass, tempered glass, laminated glass, and insulated glass units (IGUs), each with specific properties suited for different applications.
  • STRUCTURAL SUPPORT: Glazing systems rely on a robust framework to support and hold the glass panels in place. The structural support can be made of aluminum, steel, or other materials with the necessary strength and stability to withstand external forces such as wind and seismic activity. The framework provides the necessary rigidity while also allowing for the desired aesthetics and architectural form.
  • SEALING AND WEATHERPROOFING: To ensure the longevity and performance of the glazing system, proper sealing and weatherproofing  measures are essential. Sealants, gaskets, and weatherstripping is used to create an airtight and watertight barrier between the glass panels and the supporting structure. This helps prevent moisture infiltration, air leakage, and thermal inefficiencies, maintaining a comfortable indoor environment.
  • INSULATION AND ENERGY EFFICIENCY: Glazing systems can incorporate insulation features to improve energy efficiency and thermal performance. Double glazing or triple glazing with sealed air or gas-filled gaps between the glass layers minimize heat transfer, reducing energy consumption for heating and cooling purposes. Low-emissivity (Low-E) coatings can also be applied to glass surfaces to enhance insulation properties and control solar heat gain.

Glazing systems offer a blend of aesthetics, functionality, and sustainability. Egan’s experienced InterClad team is committed to sustainability and has built hundreds of commercial projects by developing, installing, and maintaining their glazing systems.
