Reduce Air Leakage with a Durable Vapour Control Barrier

DuPont™ AirGuard® Control is designed to reduce uncontrolled air leakage and minimise convective heat loss in roofs, walls and floors.

A continuous layer of DuPont™ AirGuard® Control reduces air leakage by providing an effective vapour control barrier to control air movement and moisture infiltration around the habitable space of the building.




Key Benefits of DuPontTM AirGuard® Control

Although specifically developed for use as a vapour control barrier, this advanced product also provides other important advantages, including:

  • Reduced convective heat losses
  • Reduced risk of condensation in the insulation
  • Transparency for easier installation of insulation
  • Limited vapour transmission
  • Airtightness and water resistance
  • Superior mechanical strength
  • Light weight – making it easy to install
  • Reaction to Fire: Class E
  • CE-conformity for plastic and rubber vapour control layer (EN 13984)
  • BBA-Approved
