ROCKWOOL Techwrap2

Application

Reducing unwanted sound through pipework and ductwork can be challenging. Techwrap2 is a high performance acoustic solution for various types of pipework and ductwork that combats these challenges.

It has been specially engineered to facilitate the highest standard of noise control to circular ductwork.

Description

ROCKWOOL Techwrap2 is a laminate product made up of ROCKWOOL stone wool insulation, acoustic membrane and a layer of reinforced aluminium foil.

It can provide thermal and acoustic insulation to pipework and equipment operating at temperatures ranging from 0–230°C, though outer facing temperatures should not exceed 80°C.

Features and benefits:

  • The superior acoustic performance is maintained by preserving thickness at corners, bends and fixing locations.
  • An easy to apply as one single application, allowing for efficient installation.
  • The material can simply be cut with a sharp knife and shaped to specific duct sizes.
  • The product has excellent insulation properties up to 230°C, suitable for most duct types.

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). 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.
