Understanding Structural Glazing vs Curtain Glazing
Both structural and curtain glazing offer unique advantages that cater to different architectural needs and aesthetic preferences. Structural glazing is ideal for modern designs that require a seamless appearance and integrated load-bearing capacity.
The difference between structural glazing and curtain glazing, though both are used for glass facades in modern buildings, is that they differ significantly in their construction, appearance and function, as well as their construction methods and structural support.
Understanding the differences between structural glazing and curtain glazing can help architects and builders choose the right approach for their projects, ensuring both aesthetic appeal and structural integrity. Read on to get an understanding of the difference between structural glazing and curtain glazing.
What is Structural Glazing?
Structural glazing is a glazing system where the glass panes are bonded directly to the structural framework of a building using adhesives. This technique allows the glass to bear some of the load, creating a cohesive appearance without visible framing elements. The key features of structural glazing include:
Adhesive Bonding
This is where the glass is attached to the frame using high-strength sealants, which act as both adhesive and weatherproofing agents.
Load-Bearing
The glass can help support the building’s structural loads, contributing to the overall strength of the facade.
Aesthetic Appeal
With minimal framing, structural glazing creates a sleek, modern look, often on high-end commercial and residential building projects.
Air and Water Tightness
Proper sealants and careful installation ensure excellent air and water tightness.
Thermal Performance
Structural glazing systems can be designed to improve energy efficiency by incorporating insulated glass units
Applications Include:
-
- High-rise buildings.
- Glass Facades
- Commercial complexes.
- Corporate offices.
- Frameless glass structures
- Load bearing glass
What is Curtain Glazing?
Curtain glazing is another name for curtain walling, and is a widely used façade system used in modern architecture, known for its aesthetic appeal, energy efficiency and structural flexibility. It plays a key role in creating visually striking exteriors for commercial, institutional and high-rise buildings.
Curtain glazing involves a non-load-bearing wall system, where the glass panels are supported by a framework of metal or other materials. This framework is then anchored to the building’s structural elements. The main purpose of curtain glazing is to allow natural light into the building, provide weather resistance and enhance thermal performance.
Applications Include:
-
- Skyscrapers and large commercial buildings.
-
- Multi-story retail buildings.
-
- Institutional and cultural buildings.
