FIREPRO® DuctRock® Slab

Application

Designed to provide up to 2-hours’ fire protection to ductwork in addition to fire resistance where they pass through fire rated walls and floors.

Description

FIREPRO® DuctRock® Slab is composed of high density, non-combustible mineral wool insulation, finished with a high emissivity black foil facing. FIREPRO® Glue and high performance Black Aluminium Foil Tape are available for sealing all board joints. The ROCKWOOL DuctRock® slabs are readily available in three thicknesses, are easy to handle and simple to install. The slabs can be installed using stud welded pins, steel washers and FIREPRO® Glue, and are easy to cut with a hand saw or circular/table saw.

DuctRock® Slab has been tested to the latest harmonised European standard and is capable of achieving a fire resistance up to EI 120, up to 2-hours’ fire protection for rectangular ventilation and smoke extract ducts and up to 1 hour fire protection to ducts with a combustible lining (kitchen extract) ducting. The solution is typically used in commercial and industrial settings where they travel throughout the building passing through fire rated walls and floors.

Insulating ductwork can be beneficial for reducing thermal transmission as well as protecting the structure in the event of a fire which can amount to costly damages. All joints are to be filled with FIREPRO® Glue (see separate product) and held tightly closed.

Features and benefits:

  • EI 120 mins on ventilation and smoke.
  • Tested on both vertical and horizontal ducts.
  • Wide ranging scope for many duct types.
  • High quality black foil finish.
  • Patented horizontal penetration detail.

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:

Designed to provide up to 2-hours’ fire protection to ductwork in addition to fire resistance where they pass through fire rated walls and floors.
