Service overview
How Vortexen delivers this capability.
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.

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.
