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.
