Rockwool Ductwrap

Ductwrap is a lightweight and flexible insulation roll faced with reinforced aluminium foil.

Ductwrap is suitable for both circular and rectangular ductwork. This solution is recommended for service temperatures of up to 230˚C. The thermal insulation solutions are often applied to air conditioning, warm air and extractor ducts, located in plant rooms, boiler houses or externally.

In addition to its thermal properties, the mineral wool insulation delivers acoustic performance which can be desirable for applications to ducts that carry gases, fluids or particle solids at high velocities. The use of ROCKWOOL Ductwrap can also significantly improve the level of environmental sound, for a far more pleasant working environment.

Features and benefits:

• Acoustically absorbent.

• Non-combustible.

• Water repellent.

• Chemically inert.

• Easy to handle and install.

• CE marked in accordance with BS EN 14303.

• LUL approved.

Acoustics

The use of Ductwrap and Ductslab can considerably improve the level of environmental sound. For higher standards of acoustic attenuation, ROCKWOOL Techwrap can be used to provide both thermal and acoustic insulation.

pH neutrality

ROCKWOOL insulation is chemically compatible with all types of pipes, ducts, equipment and fittings. (Guidance is given in BS5970 regarding the treatment of austenitic stainless steel pipework and fittings). Stonewool 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.

Water vapour resistance

When suitably taped, the aluminium foil gives Ductwrap and Ductslab a water vapour resistance of approximately 1000 MNs/g.

Application:

In order to regulate temperature within heating, ventilation and air conditioning systems insulation must be applied. ROCKWOOL Ductwrap can provide the thermal insulation to these HVAC systems as well as cold water storage, feed and expansion tanks. This solution is acoustically absorbent and A1 non-combustible to deliver the highest level of fire performance.
