The hidden vertical route
The gap behind curtain wall can become a path for fire and smoke if slab-edge continuity is not maintained.
Assembly details matter
Façade type, spandrel construction, mullions, insulation orientation, compression, supports, smoke seal and movement must align with accepted evidence.
Inspect before closure
Once façade or internal finishes remove access, missing or displaced components become expensive to verify and repair.
What to verify
- Façade shop drawings
- Slab-edge dimensions
- Spandrel construction
- Safing density and compression
- Smoke-seal detail
- Movement requirement
- Inspection hold point
