Cavity barriers (C06 S07)

Fire separation within concealed spaces.

Regulatory requirements demand that cavities and concealed spaces, in the structure or fabric of a building, are sub-divided or sealed by means of cavity barriers or fire-stopping to restrict the hidden spread of smoke and flames. This is of prime importance since many buildings are honeycombed with concealed cavities and voids within the roofs, floors, and walls.

Key benefits

  • Cavity barrier performance options to match partition performances up to 60 minutes fire resistance
  • Fire separation is maintained throughout the life of the building due to the board lining being mechanically fixed
  • High level of component commonality with GypWall partition systems
