Description

Cavity barriers designed for installation within cavities where ventilation is required in service use. Manufactured from non-combustible rockfibre mineral wool with a reactive intumescent layer, the cavity barrier can provide an air gap of up to either 25 or 44 mm. The intumescent layer will rapidly expand when exposed to heat in a fire event, closing off the air gap and preventing vertical fire spread within the external wall cavity.


Features and benefits:

  • Reactive intumescent element.
  • Either 60 minutes or 120 minutes fire integrity.
  • 25 mm or 44 mm air gap for ventilated cavity.
  • Tested for ASFP TGD19 standards.
  • Fixing brackets included as standard.


ARC OSCB open state cavity barriers should be partnered with ARC Fire Stop Slab installed vertically for a complete cavity barrier solution.
