Glass buildings turn heads. But have you ever looked at a glass wall and wondered how it stays up without any visible frame? That’s the magic of spider glazing systems.
At CJ Facade, we design and install spider glazing systems for homes, offices, malls, and airports. In this guide, we’ll explain what spider glazing is, how it works, and why it might be the right choice for your next project.
What Is a Spider Glazing System?
A spider glazing system is a way to hold glass panels in place using metal fittings shaped like spiders. Each fitting has several “legs” that grip the corners of the glass. The legs then bolt onto a steel frame behind the glass.
There are no visible metal frames around each pane. The result? A clean, open, all-glass look. This style is also called structural glazing or frameless glazing.
How Does Spider Glazing Work?
The system has three main parts. Let’s break them down.
1. Glass Panels
The glass is usually toughened or laminated. This makes it strong enough to handle wind, heat, and daily wear. Holes are drilled into the corners of each panel during manufacturing.
2. Spider Fittings
These are the star of the show. Each spider fitting has two, three, or four arms. The arms bolt through the drilled holes in the glass. This spreads the weight evenly across each panel.
3. Support Structure
Behind the glass sits a hidden frame. This frame can be made of steel trusses, cables, or glass fins. It carries the full load of the glass and passes that load down to the building’s core structure.
Together, these three parts create a wall that looks like it’s floating.
Why Choose Spider Glazing Systems?
Here’s why architects and builders love this system.
- Unmatched views. With no thick frames in the way, you get clear, uninterrupted views.
- More natural light. Sunlight fills the space, cutting down on the need for artificial lighting.
- Modern appeal. A frameless glass wall gives any building an upscale, contemporary look.
- Strong and safe. Despite the light appearance, these systems meet strict safety standards for wind and seismic loads.
- Design freedom. Architects can create curved walls, sloped roofs, and tall atriums that would be hard to build with normal frames.
Where Are Spider Glazing Systems Used?
You’ll spot spider glazing in many kinds of buildings, such as:
- Shopping malls and retail stores
- Corporate offices and lobbies
- Airports and railway stations
- Luxury homes and villas
- Museums and exhibition halls
- Hotel entrances and atriums
If a building wants to make a strong first impression, spider glazing is often the answer.
Spider Glazing vs. Traditional Curtain Wall Systems
So, how does spider glazing compare to a standard curtain wall? Traditional curtain walls use visible frames, called mullions, to hold the glass. Spider glazing skips the frame and uses point fixings instead.
This means spider glazing offers a cleaner look. However, it often costs more to design and install. It also needs careful engineering, since each spider fitting must carry its share of the load without any backup frame around the glass edge.
For projects where appearance matters as much as function, spider glazing is usually worth the extra investment.
What to Consider Before Installing Spider Glazing
Before you commit to a spider glazing system, think about the following points.
- Wind and weather loads. Your local climate affects how much load the glass and fittings must handle.
- Glass thickness and type. Thicker, laminated glass adds safety but also adds weight and cost.
- Maintenance access. Someone will need to clean and inspect the glass and fittings regularly.
- Budget. Spider glazing costs more upfront than standard framed glass, but it can raise a property’s value.
- Experienced installer. This system demands precise engineering. A small error can affect the whole wall.
That last point matters most. A poorly installed spider glazing system can lead to leaks, glass stress, or safety risks.
