Tyvek® Enercor® Roof - Vapour open roof underlay
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:
- Protection against all possible heat losses: radiation, convection and conduction.
- 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®.
