Fireseal Party Wall Batt – for vertical joints applications only

Bradford Fireseal Party Wall Rock-wool Insulation Batts is designed for installation in Party Wall vertical joints applications only, it is not appropriate to be used to seal areas at the top of either a masonry or lightweight wall system. Fireseal Party Wall Batts may also be stacked to fill cavities up to 255mm in height. Multiple layers must be stacked neatly and should be installed as one unit.

Bradford Fireseal Party Wall Batts are made from non-combustible Rock-wool, which is specifically designed to meet the fire protection requirements for inter-tenancy walls in multi residential applications.

Fireseal Party wall Batts are designed to reduce fire hazards by separating one dwelling from another to provide the building occupants with the maximum time to escape safely by maintaining sufficient structural adequacy, integrity and insulation. There are principally 3 key areas for reducing fire hazards:

  • Controlling fire within a compartment
  • Controlling the spread of fire between compartments through openings in external walls
  • Providing early warning to building occupants

The incorporation of the correct insulation products in the design of passive fire protection systems can save lives and also complement the installation of active fire protection equipment (i.e. sprinkler systems and fire alarms).

BCA provisions

Party Wall Sealer applications for wall perimeter and cavity junctions in Class 1 Buildings need to meet the relevant Deemed to Satisfy requirements of Clause of Volume 2 of the Building Code of Australia (BCA). Inclusion of fire rated building products such as insulation are covered by the BCA.

BCA specifies required levels of fire resistance for walls that separate one dwelling from another, expressed as the Fire Resistance Level (FRL) of the wall in minutes. The fire rated walls must maintain sufficient:

  • Structural adequacy – ability of a structure to maintain its stability and ability to hold up other parts of the structure.
  • Integrity – ability of a structure to resist the passage of flames and hot gases.
  • Insulation – ability of a structure to maintain a temperature below specified limits on the surface on the other side of the wall.
