Curtain wall
An exterior wall system that does not carry the building’s floor or roof gravity loads, typically supported by the structural frame.
Why it matters
Its performance depends on glazing, framing, anchors, seals, and drainage. Leakage observations may require targeted testing to distinguish a failed joint from another source.
In practice
A project example
Water appears below a window, but the entry point is an interface several feet above it.
