Fire Stopping

“Fire Stopping” is the sealing of openings or gaps to prevent fire, smoke and heat from passing through multiple building spaces.

Any openings or gaps should be sealed to restrict the lateral or vertical fire spread.

The selection and installation of the correct fire stopping products is essential to prevent smoke and heat from a fire spreading through a building.

Legislation for Fire Stopping

Principle Control of Fire Spread and limitation of damage is principally achieved through compartmentation of a building.

These compartments are bounded by fire resisting elements:-

  • Walls
  • Floors
  • Ceilings

Fire resisting elements are often breached to permit access for services or functional joints:-

  • Cables
  • Pipes
  • Ventilation systems
  • Gaps between fire resisting elements and around the penetrations must be sealed so that the fire integrity of the fire – resisting element is maintained.

RES are FIRAS certified for Penetration Sealing

Why does Fire Stopping need to be carried out?

“If a fire separating element is to be effective, then every joint, or imperfection of fit, or opening to allow services to pass through the element, should be adequately protected by sealing or firestopping so that the fire resistance of the element is not impaired”

Extract from Building Regulations (Republic of Ireland) 1997 – Document B. 10.
