Fire Curtain

Even if you have heard of fire curtains and smoke barriers, it is easy to become confused by the technical specifications and terminology that surround them. We hope to explain in simple language what a fire curtain is and most importantly, why they are needed.

Put simply, a fire curtain is a specially constructed curtain that descends from the ceiling to block an opening and stop fire and smoke spreading between two areas. In larger structures, several fire curtains are used which divide the building into ‘fire compartments’ when there is a fire.

This is called ‘compartmentation’ and is a fundamental element of passive fire protection in buildings. It helps to:

  • Provide time for people to escape
  • Protect escape routes
  • Allow time people for firefighting services to arrive
  • Protect property

Structure of a Fire Curtain

A fire curtain is similar to a metal roller shutter in that it descends vertically as it un-rolls from a ‘top box’, however because a fire curtain is made of a woven fiber glass material, it is much more flexible and compact.

This means a curtain can be more closely fitted within a space and therefore provides much better compartmentation.

The compact construction of fire curtains makes them an ideal choice for lobbies, hatches and stairwells where there is limited space. When included in the design stage of a building, they can be recessed into walls and ceilings leaving a thin slit as the only indication that the curtain is there.

There are several types of fire curtain:

Certification and Standards

All fire curtains must be rigorously tested and certified. These standards ensure that the integrity of a curtain will remain for a certain minimum length of time and that they will continue to work in the extreme conditions of a fire.

A fire curtain is used where, if there is a fire, it is necessary to create a temporary barrier within an opening that seals off the area on fire. The curtain descends and prevents any fire and smoke from spreading from one area to another. It also allows people access to protected escape routes without any loss of fire resistance.
