It’s a wrap. 

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.


ROCKWOOL Techwrap2 is a laminate product made up of Acoustic Membrane and a layer of reinforced aluminium foil. It has been specially engineered to facilitate the highest standard of noise control to circular ductwork.

Techwrap2 can provide thermal and acoustic insulation to pipework and equipment operating at temperatures ranging from 0˚C to 230˚C, though outer facing temperatures should not exceed 80˚C. 75mm wide plain aluminium foil self-adhesive tape should be used to seal all joints. 

ROCKWOOL mineral wool insulation products have been proven to have a sustainable performance lifetime of over 60 years.

  • The superior acoustic performance is maintained by preserving thickness at corners, bends and fixing locations 
  • ROCKWOOL Techwrap2 is 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.
  • Techwrap2 has excellent insulation properties up to 230˚C, suitable for most duct types.
