Fire Barrier Systems

Reducing concealed risk

Fire Barrier Systems are essential to prevent the rapid spread of fire in concealed spaces within a building. The ROCKWOOL Fire Barrier and Fire Barrier Slab have been specially developed to offer easy to install solutions which effectively prevent the spread of fire and smoke within unseen roof and ceiling voids.


As a labour saving, easy to install fire resistant insulation product,  the ROCKWOOL Fire Barrier systems offer essential prevention against fire and smoke in hidden spaces. As part of the comprehensive FIREPRO® range of products, the ROCKWOOL Fire Barrier and Fire Barrier Slabs feature a patented 'Quick Fix' support system, which offer a quick, cost effective solution for periods of up to 60 minutes.  The ease of installation significantly reduces the risk of error, whilst extended drops are easily catered for as the system can maintain its performance in void heights of up to 10.5 metres. As vertically hung Fire Barriers, they are able to offer integrity and insulation protection periods from 15 to 120 minutes, in addition to the friction fitted Fire Barrier Slab which also provides 60 minutes integrity and insulation. It is ROCKWOOL’s essential insulation performance, that effectively limits heat transfer through the barriers. This prevents the ignition of any combustible materials in the surrounding areas.



ROCKWOOL Fire Barrier and Fire Barrier Slab achieve a reaction to fire classification of A1 as defined in BS EN 13501:1 / Fire barrier Systems have been independently tested and assessed to BS 476: Part 22 by accredited laboratories. LPCB and LUL approved.

  • Patented quick fit system providing fire resistance for up to 1 hour.
  • Acoustically effective – contributes to improved sound reduction benefits as the correct use of Fire Barrier within structural cavities and voids will minimise transmitted sound.
  • Quick installation – the Fire Barrier Systems can be fixed to concrete decks, timber and steel meaning that the cost of installation is reduced, and the speed of installation is increased.
  • Flexible – the ROCKWOOL Fire Barrier has a 25mm galvanised wire mesh for increased strength. Available with an aluminium foil face to reduce the passage of smoke.
