Introduction
When planning a modern glass façade, many people ask: Can spider glazing be fitted in DGU (Double Glazed Unit) glass? The short answer is yes. Spider glazing with DGU glass is possible, but it needs special fittings and careful planning. This combination is popular in commercial buildings because it gives both a stylish look and better energy efficiency.
What is DGU Glass?
DGU stands for Double Glazed Unit. It is made of two layers of glass with a gap (usually filled with air or gas) between them. This design helps in:
-
Reducing heat transfer.
-
Improving sound insulation.
-
Making interiors more energy efficient.
What is Spider Glazing?
Spider glazing is a modern glass fixing system where spider fittings (metal arms with point supports) hold the glass instead of traditional frames. It is widely used in:
-
Malls
-
Office towers
-
Airports
-
Showrooms
The result is a clean, seamless, and transparent façade.
Can DGU Glass Be Used in Spider Glazing?
Yes, but there are a few important points:
-
Glass Thickness & Weight
-
DGU glass is thicker and heavier than single glass.
-
The spider fittings and structure must be strong enough to handle the extra load.
-
-
Edge Treatment
-
Spider glazing needs holes drilled in the glass.
-
For DGU, both layers must be drilled, and the spacer seal must stay intact.
-
This can only be done in a factory with special machines.
-
-
Special Spider Fittings
-
Standard fittings are for single glass.
-
DGU glass requires longer bolts and custom spacers to hold the thicker unit.
-
-
Safety
-
Always use toughened or laminated DGU for spider glazing.
-
Engineers must check wind load and point load before installation.
-
Benefits of Using DGU in Spider Glazing
-
Better thermal insulation (keeps inside cool in summer and warm in winter).
-
Noise reduction, ideal for offices and busy areas.
-
Modern aesthetic appeal with full-glass transparency.
-
Adds value and comfort to the property.
Conclusion
Yes, spider glazing can be fitted in DGU glass, but it requires special factory-made glass units, customized spider fittings, and professional installation. If done correctly, it provides the perfect mix of modern design, safety, and energy savings.
