Definition
A curtain wall is a facade of glass or panels on an aluminium frame, anchored to the slabs with brackets and carrying only its own weight and wind load. It is built as stick system on site or as factory-made units.
Why it matters on a project
It gives modern, bright facades, but its thermal and water performance depend on the glass, the details and installation accuracy.
Measurement and pricing
In square metres by glass and profile type, with doors and vents by number.
Common mistake
Approving profiles and glass without wind and thermal calculations, or without a site water test.
Frequently asked questions
Curtain wall or ordinary windows?
A curtain wall covers the facade on its own frame hung from the slabs; windows sit in wall openings.
Which tests matter?
A site water test, plus wind and thermal calculations in the shop drawings.
