DuPont™ AirGuard®

DuPont™ AirGuard® - 100 % Air tight vapour control layer

DuPont™ AirGuard® is a 100% air tight vapour control layer with a very low emissivity surface which significantly boosts the thermal insulation in the building.

DuPont™ AirGuard® used with Tyvek® Enercor® will provide 2 major benefits:

  1. Protection against all possible heat losses: radiation, convection and conduction.
  2. Effective moisture management due to the higher evaporation capacity provided by Tyvek® Enercor® Wall and to the reduction in moisture migration into the construction by DuPont™ AirGuard®.

This combination of these 2 products forms the basis of DuPont™ Climate Systems.
