Application

The cavity barriers can be used in both vertical and horizontal applications, providing an effective fire, acoustic and thermal barrier within external wall cavities and separating party walls.

Description

ROCKWOOL TCB Cavity Barrier and PWCB Cavity Barrier products have been created to provide excellent levels of fire protection for timber frame and masonry properties. They have been designed to meet the minimum building regulation requirements for fire resistance in concealed wall cavities, having been tested and assessed for up to 60 minutes’ integrity and insulation, thereby exceeding minimum requirements.


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 color-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.


Feature and benefits:

  • Fire resistance up to 60 minutes (EI).
  • Suitable for vertical and horizontal applications.
  • Unaffected by building movement.
  • Reduce acoustic flanking transmission.
  • Improves air leakage and heat loss.
