Application

Suitable for use in irregular applications, including:

  • Historical building upgrades.
  • Voids up to 450 mm wide.
  • Rigid and flexible walls of 100 mm minimum thickness.
  • Suitable to close up to 25 mm ventilation gaps.

Brackets should be positioned at 300 mm and 700 mm, and must be fixed to the rigid structure using no combustible fixings. A minimum of two brackets should be used per 1200 mm length.

Consult manufacturer to view performance data in different applications.

Description

Non-ventilated, open state cavity barrier with a black encased elastomeric flexible intumescent edge. Can be fully encased. Designed to keep tight within the gap but allow movement within the building.

Features and benefits:

  • The integrated aluminium foil facings provide class ‘O’ rating and high resistance to smoke.
  • Resilient lateral compression ensures a tight fit.
  • High speed, easy installation with minimal waste.
  • No Volatile Organic Compounds (VOCs).
  • No curing time is required.
  • Low maintenance system with long life.
  • Dynamic movement testing of 500 cycles per 30 minutes.
  • Moisture and weather resistant.
  • Sustainable, and contributes to green building.
  • Life expectancy of over 25 years.
