The ARC Rockfibre Insulated DPC serves as a fire-rated cavity closer explicitly created for sealing the cavity encircling window and door openings in coordination with a return block. This closer fits snugly between the return block and the inner edge of the outer brickwork layer. The rockfibre insulation not only mitigates cold bridging but also eradicates issues of moisture, mould, and staining that might arise around windows and doors.

Features and Benefits:

  • Closes cavity around window and door reveals
  • Prevents cold bridging
  • Insulated with non-combustible rockfibre mineral wool
  • Use in conjunction with a return block
