FAQ
Frequently Asked Questions
No, a curtain wall is a non-load-bearing element. It supports only its own weight and transfers wind and other loads to the building's primary structure.
A curtain wall is typically continuous and runs past the floor slabs on the outside. A window wall is usually installed between floors, sitting on the slab edge.
Common materials include aluminium frames, glass infill (often insulated), metal panels, stone veneer, and composite materials.
In a castle, a curtain wall was a defensive outer wall that connected towers and gatehouses, creating a protected enclosure or bailey.
