Tyvek® Enercor® Roof - Vapour open roof underlay

Reflect heat and reduce radiated heat loss

Tyvek® Enercor® Roof is a vapour open roof underlay with a metallised low emissivity surface which reflects heat in summer and reduces radiated heat loss in winter.

Tyvek® Enercor® Roof 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® Roof 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 .
