Fire protection for ventilation, smoke extract and kitchen extract ducts.
Fire Duct sections provide fire protection to circular steel ductwork (in vertical and horizontal applications).
Fire duct section provides fire protection, thermal and acoustic insulation for circular ductwork. The simplicity and flexibility of fixing options ensures rapid and reliable installation to both vertical and horizontal duct systems. All Fire duct products are supplied faced on one side with reinforced aluminium foil. Fire Duct Section is made up of high density pre-formed pipe section faced with reinforced aluminium foil.
Fire Duct PSM is formed of high density slab with factory machined grooves to allow for installation around larger circular ducts, again reinforced with aluminium foil. Fire Duct Section for ducts of a diameter between 17 mm and 610 mm, and Fire Duct PSM for circular ducts with a diameter greater than 406 mm. The systems provide comprehensive performance for stability, integrity and insulation, for all ducts passing through fire-rated walls or floors.
