Fire Stopping

The fundamental premise of modern fire protection is based on the principles of compartmentation. Every building is designed into several fireproof compartments, to prevent or slow the spread of fire and smoke from one compartment to another. Essential building services — water pipes and electrical cables, for example - penetrate compartment walls and ceilings. These have the potential to seriously risk the integrity of the fire compartment, unless special and proven fire stopping systems are employed. Promat fire stopping systems restore the fire compartment to its original levels of fire performance.

Promat provides a number of integrated and effective fire stopping solutions, and these include the successful and easy to install PROMASTOP® and PROMASEAL® systems:

  • fire stopping sealants
  • intumescent fire stopping sealants
  • fire stopping silicone
  • water based coatings
  • fire stopping collars for plastic and metal pipes
  • fire stopping expanding wraps
  • permanently elastic intumescent bricks and plugs
  • fire stopping graphite-based pillows
  • fire stopping mortars
  • intumescent seals and sealing systems

Fire Stopping Systems

Fire Stopping Systems

To create a comprehensive passive fire protection system, all gaps in walls, floors and ceilings need to be fire stopped to prevent the spread of flames, smoke and toxic gases. These holes vary in size from single cables through to cable bundles, cable trays, ducts and pipes of varying shapes and sizes. Gaps can also be designed-in to accommodate structural movement within the building.

Advantages

  • Tested with board products
  • Comprehensive range of solutions
  • Easy installation
  • Movement capability

Design Considerations

Design Considerations

Every service passing through fire resistant building elements will react in a different way during a fire, so there is no single solution or product that will protect all services.

To ensure a wall or partition will provide the required fire performance, specifiers should consider:

  • Fire resistant period
  • Insulation requirement
  • Wall, floor, linear gap
  • Movement – vibration and thermal expansion
  • Mechanical strength – load bearing


Chapter 7 of the Fire Protection Handbook provides examples of system specifications for a range of fire stopping products. Additional system details are available in the Technical Data Sheets.
