When you look at today’s stunning modern buildings, one thing often stands out: the glass. From sleek high-rise offices to stylish homes, large glass facades give structures a clean, sophisticated feel. But behind these beautiful surfaces are smart engineering choices — mainly between structural glazing vs curtain wall systems. If you’re planning a commercial or residential project and want that seamless glass look, knowing the difference is crucial.
MANNLEE, known for its high-quality architectural glass systems like curtain walls, glass railings, and interior partitions, helps clients across many industries make these choices every day. Here’s a straightforward look at how these systems differ, when you might pick one over the other, and how mannleecw.com can bring your vision to life.
What is a Curtain Wall System?
A Complete Outer Skin
A curtain wall is essentially a non-structural outer covering of a building. It’s designed to keep the weather out and the occupants comfortable inside, but it doesn’t carry any of the building’s load — that’s what the structural frame is for. Because of this, curtain walls can be made almost entirely of glass supported by lightweight aluminum or steel frames.
Versatile and Modern
Curtain walls are popular in office buildings, hotels, and even upscale residential towers. They allow for large expanses of glass, flooding interiors with natural light and giving occupants amazing views. Beyond aesthetics, modern curtain wall systems also improve energy efficiency by using double or triple glazing and thermal breaks.
What is Structural Glazing?
A Frameless Glass Look
Structural glazing takes minimalism a step further. In this system, glass panels are bonded directly to the structural frame of the building using special silicone sealants, or sometimes supported by discreet fittings. This eliminates the need for visible external frames.
The result? A smooth, uninterrupted glass facade that almost looks like a single sheet. Architects often pick structural glazing when they want to create that high-end, futuristic feel on a building’s exterior.
Great for Creative Shapes
Structural glazing isn’t limited to flat surfaces. It’s also used for glass canopies, skylights, and even complex curved facades. With the right engineering, it opens up countless design possibilities.
Structural Glazing vs Curtain Wall: How to Choose
Appearance and Design Goals
If you want your building to have a perfectly flush glass surface with no visible external frames, structural glazing is usually the top pick. It creates a dramatic, ultra-modern look that’s hard to achieve any other way.
On the other hand, curtain walls still deliver impressive glass facades but show slight framing lines. Many architects like these subtle lines because they add texture and rhythm to a building’s appearance.
Budget Considerations
Generally, structural glazing systems require more specialized engineering, custom fabrication, and careful installation. This can make them more expensive than typical curtain walls. Curtain walls, with their modular frames, can be quicker to manufacture and install, often saving on costs.
Maintenance and Repairs
Curtain walls are modular, so if a glass panel ever gets damaged, it’s easier to replace just that section. Structural glazing systems can be trickier to repair since the glass is bonded directly to the structure, sometimes needing more careful removal and replacement.
Thermal and Weather Performance
Both systems today can meet high standards for insulation and waterproofing, especially when designed by experts like MANNLEE. However, traditional curtain walls have a long track record with drainage systems and integrated seals that handle weather extremely well.
Where MANNLEE Comes In
Expertise You Can Trust
Whether your project leans toward structural glazing or curtain walls, MANNLEE brings years of experience in architectural glass systems to the table. They’ve worked on everything from sleek commercial towers to luxury homes, ensuring each project meets exacting standards for looks, safety, and long-term performance.
Custom Solutions for Every Project

MANNLEE doesn’t stop at building envelopes. They also create elegant glass railings for balconies and staircases, as well as stylish partitions that make interior spaces feel open yet defined. These products carry the same commitment to quality and modern design.
Examples Where Each System Shines
Ideal Projects for Curtain Walls
- Office Towers: With consistent floor layouts, curtain walls can be quickly assembled floor by floor, saving time and costs.
- Hotels: They allow for large window walls that still integrate shading or operable windows where needed.
- Shopping Centers: Curtain walls can incorporate dramatic entrances and atriums while balancing budget concerns.
When Structural Glazing Steals the Show
- Corporate Headquarters: Companies looking to make a bold architectural statement often choose frameless glass.
- High-End Residences: Structural glazing around large patios or two-story living rooms creates a stunning seamless indoor-outdoor feel.
- Museums or Galleries: These buildings benefit from expansive glass that doesn’t distract from views or exhibits inside.
