Perimeter Fire Containment

Curtain-wall edge-of-slab fire containment using assembly-specific safing, smoke seal and spandrel coordination.

Technical scope

Control the slab-edge and façade path between floors.

Perimeter fire containment addresses the void between a rated floor slab and the exterior curtain wall or façade. A failure here can permit vertical fire and smoke spread between storeys.

Façade geometry, mullions, spandrel construction, safing insulation, smoke seals and movement vary. The installed route must correspond to the actual tested or assessed assembly.

What this route refuses to hide.

Fast progress is valuable only when assumptions, responsibility and limitations remain visible to the buyer and delivery team.

01No generic mineral-wool stuffing
02No omitted mullion detail
03No compressed-safing guesswork
04No façade closure before inspection
