Curtain Wall Systems in London
Home » Architectural Glazing »
Design meets engineering in every façade we build.
At Bigness Group, we specialise in curtain wall systems — high-performance architectural façades that combine strength, energy efficiency, and visual elegance.
From commercial developments to modern residential blocks, we design, fabricate, and install curtain walls that define the skyline of London with precision and confidence.
Our systems merge light, structure, and insulation — turning glass into performance.
What Is a Curtain Wall System
A curtain wall is a lightweight, non-structural façade that hangs from the building frame and carries only its own weight.
It protects the interior from weather, improves thermal efficiency, and defines a project’s architectural identity.
At Bigness Group, we design and install both stick-built and unitised curtain wall systems, ensuring every façade meets modern standards for wind load, air tightness, and fire resistance.
We combine advanced fabrication with on-site precision to deliver façades that perform as beautifully as they look.

Frequently Asked Questions
Q: What’s the difference between stick-built and unitised curtain walls?
Stick-built systems are assembled piece by piece on site, ideal for complex geometries; unitised systems are pre-assembled panels for faster installation.
Q: Can you provide design and structural calculations?
Yes. We provide full design packages, including thermal modelling, deflection analysis, and load calculations.
Q: Are your curtain walls energy-efficient?
Absolutely. All systems use thermally broken aluminium profiles and double or triple glazing for optimal insulation.
Q: Do you offer maintenance or aftercare?
Yes — we provide scheduled inspection and cleaning packages to maintain performance and appearance.
