How to Become a Curtain Wall Installer in the UK (2026 Guide)
Overview
Curtain wall installers fit the glass and aluminium facade systems that define modern commercial buildings. These non-structural exterior walls hang from the building's structural frame like a "curtain" and provide weather protection, thermal insulation, and aesthetics. It's a specialist branch of glazing that combines engineering precision with construction skills. Major UK developments, from Canary Wharf towers to Manchester's skyline, all rely on skilled curtain wall installers.

Frequently Asked Questions
How much do curtain wall installers earn?▼
Trainee installers earn £22,000-£28,000. Qualified installers earn £32,000-£45,000. Lead installers and supervisors earn £42,000-£55,000. Specialist structural glazing skills command the highest rates.
What is the difference between curtain walling and standard glazing?▼
Standard glazing fills openings in walls. Curtain walling is the entire external wall system — a non-load-bearing facade of glass and aluminium that hangs from the building structure. It's more complex and requires specialist skills.
Do I need to be comfortable with heights?▼
Absolutely. Curtain wall work takes place on the exterior of multi-storey buildings, often using cradles, mast climbers, or scaffolding. If you're uncomfortable with heights, this isn't the right trade.
What systems do curtain wall installers work with?▼
The two main types are stick systems (assembled piece by piece on site) and unitised systems (pre-assembled panels craned into position). Each requires different skills, and most installers learn both.
Is curtain walling a growing industry?▼
Yes. Commercial construction, office refurbishments, and the trend for glass-heavy architectural designs keep demand strong. Energy efficiency requirements also mean older curtain wall systems need upgrading or replacing.
