Application

Fire protection for circular and rectangular steel ductwork (in vertical and horizontal applications). Up to two hours' fire protection for stability, integrity and insulation.

Description

Fire protection of steel ductwork is important to stop the spread of fire through building services, which if breached can allow fire to spread rapidly throughout the building. Fire Duct Systems provide fire protection to rectangular steel ductwork (in vertical and horizontal applications).


There are three products within the ROCKWOOL Fire Duct System; Fire Duct Slab, Fire Duct Section and Fire Duct PSM, each specially designed for different applications. Fire Duct Slab is composed of high-density insulation slab which is faced with reinforced aluminium foil. Fire Duct Slab is best suited to rectangular duct applications. Fire Duct Section and Fire Duct PSM are designed for circular ductwork (specified separately). The systems provide comprehensive performance for stability, integrity and insulation, for all ducts passing through fire-rated walls or floors.


Features and benefits:

  • Quick and easy to install.
  • Fully certified to BS 476–24 (duct types A and B).
  • Up to two hours' fire protection for stability, integrity and insulation.
  • Choice of fixing options.
  • Single layer, enabling verification of system installation.
