DuoDuct External Duct Slab

Application

Designed for use with rectangular and square external duct work carrying warm air, chilled air or dual purpose duct systems. Recommended for ductwork with service temperatures up to 230°C.

The slab is also suitable for use within plant rooms, low level plant work applications and areas where there is an increased risk of impact damage. Circular Ductwork In addition to DuoDuct Slab for rectangular or square external ductwork, ROCKWOOL offer a range of products that are suitable for use on circular external ductwork and this includes:

  • RockLap H&V Pipe Sections which are suitable for outside diameters ranging from 17–406 mm.
  • Pipe Section Mat which is suitable for larger circular ductwork ≥406 mm.

Description

The outer surface. The robust outer layer provides enhanced impact resistance and a suitable substrate for surface applications such as cladding.

Designed for use on rectangular or square external ductwork, ROCKWOOL DuoDuct is suitable for insulating cold air, hot air and dual-purpose duct systems – withstanding service temperatures of up to 230°C. The slabs are easy to cut and quick to install, allowing for increased efficiency on site.

Where duct systems require acoustic insulation, DuoDuct Slab supports a reduction in the level of environmental sounds. This is particularly useful where duct systems are carrying gases, fluids, or particle solids at high velocities.

In addition to DuoDuct Slab for rectangular or square ductwork, ROCKWOOL also offers a range of products for use on circular ductwork, including RockLap H&V Pipe Sections and Pipe Section Mat.

Features and benefits:

  • Euroclass A1 non-combustible.
  • Sound absorbent.
  • Suitable for use with self-adhered external duct membranes.
  • Dual Density technology provides impact resistance.
  • Easy to cut and quick to install.
  • CE Marked.

pH neutrality:

ROCKWOOL insulation is chemically compatible with all types of pipes, ducts, equipment 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 and offers no sustenance to insects or vermin.
