Application

  • Suitable for installation horizontally.
  • The cavity barrier must run continuously and uninterrupted apart from where it abuts the vertical cavity barrier. It must not be penetrated by other elements including mechanical or electrical services.

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.
