Firebreather® Cavity Barrier made from stainless steel grilles in a variety of sizes.
Cavity barrier for ventilated facade systems

Firebreather® Cavity Barrier

The Firebreather® Cavity Barrier is an efficient preventative fire protection solution for mounted, rear-ventilated facades. The cavity barrier consists of a stainless steel mesh and intumescent material that expands in the event of fire, immediately sealing cavities behind facades or in roof areas. It is maintenance-free, easy to install and provides fire resistance classes up to EI90​.

Use: Used as a cavity barrier in ventilated facade systems to prevent flames and smoke from rising to higher floors.

Areas of application

  • Firebreather® Cavity Barrier is suitable for:
  • Cavities in ventilated facades
  • Separation areas between floors in multi-storey buildings
  • Ventilation gaps in roof and ceiling areas
  • Fire protection in parapet ventilation
  • Protection of air gaps in building structures
  • Applications in the field of industrial fire protection sealing.

Highlights

  • Immediate seal in the event of fire, preventing the spread of fire and smoke
  • Fully passive system with no moving parts or activation systems
  • Allows for continuous ventilation behind facade cladding prior to any fire occurring

Features

  • Comprised of non-corrosive stainless steel and intumescent material
  • Complies with environmental and REACH regulations
  • Available for fire resistance classes EI30, EI60 and EI90
  • Easy to install
  • Maintenance-free

Note

The edges of the Cavity Barrier are sharp and can cause injuries. To avoid cuts, always wear appropriate protective gloves during installation.

Processing information

Preparation of installation area: Ensure that the surfaces of the wall and the façade cladding are clean, dry and free of dust, grease or other contaminations. This will ensure optimal adhesion and functionality in case of fire. Alignment and positioning: Align the Firebreather® Cavity Barrier in such a way that the intumescent strip (KERAFIX® Flexpan 200 NG-A) is positioned vertically. This alignment will allow the necessary venting behind the façade cladding under normal conditions and ensure that the material will expand correctly in the event of a fire. Fastening: Fasten the Firebreather® Cavity Barrier with appropriate screws. Sealing joints: Ensure that all joints and openings are completely sealed to ensure that there are no unwanted cavities along the Firebreather® Cavity Barrier. Additional fire protection sealing may be necessary. Final inspection: Check the Firebreather® Cavity Barrier one last time after installation to ensure correct alignment and mounting. The intumescent parts must be completely accessible so they can expand freely in case of fire and ensure proper sealing. Regular inspection and maintenance: The Firebreather® Cavity Barrier is maintenance-free, but we recommend inspection, especially after construction work or renovation, to ensure long-term functionality and integrity of the installation.
