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 circular and rectangular steel ductwork (in vertical and horizontal applications).

Application

Fire Duct Systems provide fire protection to circular and rectangular steel ductwork (in vertical and horizontal applications).

Description

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 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 60 and 356 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.

Features and benefits:

  • Quick and easy to install.
  • Fully certified to BS 476–24 (duct types A and B).
  • ½, 1, 1½ and 2 hour fire protection for stability, integrity and insulation.
  • Choice of fixing options.
  • Single layer, enabling verification of system installation.

pH Neutrality:

ROCKWOOL insulation is chemically compatible with all types of pipes, ducts, equipment and fittings. (Guidance is given in BS 5970 regarding the treatment of austenitic stainless steel pipework and fittings). Stone wool insulation is chemically inert. A typical aqueous extract of ROCKWOOL insulation is neutral or slightly alkaline (pH 7 to 9.5).

Durability:

ROCKWOOL stone wool is highly resilient, durable and dimensionally stable, maintaining its thickness and shape over time. Moreover due to its fibre structure and overall flexibility, stone wool can easily fit into available spaces, helping in avoiding unplanned air gaps, cracks or other installation errors in the final construction, ensuring stable performance over time.

Biological:

ROCKWOOL stone wool is a naturally inert and rot-proof material that does not encourage or support the growth of fungi, moulds or bacteria, or offer sustenance to insects or vermin.

Application:

Fire Duct Systems provide fire protection to circular and rectangular steel ductwork (in vertical and horizontal applications).
