Rockwool Thermal Cavity Barrier 160mm

TCB Cavity Barrier 160mm - to suit cavity 141-150mm

Thermal Cavity Barriers - TCB (Thermal Cavity Barrier) and PWCB (Party Wall Cavity Barrier) - have been developed to exceed minimum building regulation requirements for fire resistance within concealed wall cavities. Tested and assessed to BS476:Part 20 and BS EN 1366-4:2006+A1 2010, they provide up to 60 minutes fire resistance (integrity and insulation).

These cavity wall insulation products have been created from non-combustible stone wool and wrapped within a resilient polythene sleeve which acts to provide weather protection during installation. The sleeves are also colour-coded to differentiate between the two products, the TCB’s are red and the PWCB’s are white. An all in one solution, the ROCKWOOL PWCB cavity barrier also achieves the trilogy of requirements for fire safety, acoustic flanking and thermal bypass in one single product whilst providing effective perimeter edge sealing, reducing the leaking of air and associated heat loss.

Advantages:

  • Fire protection - ROCKWOOL TCB Cavity Barrier and PWCB Cavity Barrier products have been developed to exceed minimum Building Regulation requirements for fire resistance within concealed wall cavities.
  • Resilient performance – the TCB Cavity Barrier and PWCB Cavity Barrier is not affected by movement in a building, shrinkage or thermal change.
  • Durable – the barriers will withstand on-site handling and once installed will last the lifetime of the structure
  • A vertical or horizontal solution – ROCKWOOL Cavity Barriers can be used in both vertical and horizontal applications. In vertical applications, both flanges of the Cavity Barrier can be fixed to the inner leaf at 150mm centres, using staples or clout nails prior to compression fitting by outer cavity wall. In horizontal applications, only the top flange of the polythene sleeve should be fixed. 
  • Acoustic protection – ROCKWOOL Cavity Barriers prevent flanking noise transmission, along concealed cavities in both external and separating walls.
