01F / Perimeter Fire Containment

Control the slab-edge and façade path between floors.

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

Direct route

A controlled path from requirement to delivery.

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.

Commercial and technical guardrails

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

Frequently asked

Answers before the first meeting.

01Why is the spandrel zone important?+

It is part of the assembly that helps maintain floor-to-floor fire separation; its construction must align with the tested configuration.

02Is mineral wool alone a perimeter system?+

No. Density, compression, support, dimensions and smoke-seal components must match the accepted assembly.

03When should the work be inspected?+

Before façade closure removes access to the safing, smoke seal and critical interfaces.

Bring the actual requirement, evidence and deadline.
