Ducts (Cladding to Steel / Cladding)
Fire-rated duct protection systems designed to maintain the integrity and insulation of ventilation, smoke extract, and service ducts during fire exposure.
Available in two solutions — PROMATECT®-H and PROMINA® 60 — to suit a wide range of duct types, configurations, and fire performance requirements.
Both systems can be configured for internal, external, or combined fire exposure, and tested to BS 476: Part 24: 1987 (Duct Types A & B).
