Description

ARC Rainscreen Barrier is designed to provide a two-hour fire rating where continuous vertical airflow is required behind a rainscreen cladding system.

It is fixed using ARC Fixing Spike, which is fitted to the external surface of the inner blockwork. The ARC Rainscreen Barrier is then impaled onto the spike. An ARC Spacer Spike is fitted to the external surface of the Rainscreen Barrier below the intumescent strip. The Spacer Spike ensures that the 25 mm airspace is maintained along the length of the fire break.

Features:

  • Up to two hours' fire integrity.
  • Provides a 25 mm airspace behind rainscreen cladding.
  • Foil-faced to provide a smoke barrier.
  • Suitable for horizontal applications.
  • Available to suit cavity widths from 75–300 mm.
  • BRE Green Guide 'A+' rating.
  • Manufactured under ISO 9001- and ISO 14001-certified 'Quality and Environmental Systems'.
