Why perimeter fire containment is so important.

One of the most complex and least understood areas pertaining to where fire can spread remains the perimeter of a building. An understanding of fire containment is important for the safety of occupants in the building, as well as the safety of emergency responders.

Perimeter Fire Containment

Understanding curtain wall design.

A critical topic of interest today in the AEC community is the understanding of proper curtain wall design techniques using high-performance system solutions to provide fire safety in multi-story curtain wall applications.

Unprotected Perimeter Joint

Protected with a
Perimeter Fire Containment System

  • Voids exist at the intersection of a rated floor assembly and a non-rated exterior wall
  • An unprotected void at the edge of the slab potentially creates a pathway for fire and/ or smoke
  • Perimeter fire containment systems are designed to prevent fire and hot gases from entering the room above the room of origin
