Tyvek® Enercor® Wall/Tyvek® Reflex - Vapour open wall membrane

Low emissivity surface

Tyvek® Enercor® Wall/ Tyvek® Reflex is a vapour open wall membrane with a metallised low emissivity surface which reflects heat in summer and reduces heat loss in winter.

Tyvek® Enercor® Wall/ Tyvek® Reflex may be used on its own, but the overall efficiency of the system will be significantly improved when used in conjunction with DuPont™ AirGuard®.
The combination of these two products 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/ Tyvek® Reflex 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.
