Weather-Resistant Barrier with Nudura ICF

The Enviro-Dri® Weather-Resistant Barrier (WRB) System delivers superior air infiltration performance, as measured in air changes per hour, versus house wraps. Applying the Enviro-Dri WRB System on top of Nudura Insulated Concrete Forms (ICF), although not always required, gives the homeowner a piece of mind by providing an additional layer of protection in the face of volatile weather conditions.

When applied on top of the ICF the Enviro-Dri Field Membrane adds an additional layer of protection on the wall from liquid moisture such as rain, sleet and snow.

Features & Benefits

  • No need for mechanical fasteners
  • Continuous layer of protections without interruption
  • Not affected by the surfacants that can diminish the performance of wraps
  • Permanently attached from the moment of application
  • Can be sprayed or roller applied on to the ICF


Dymonic® 100 is a high-performance, high-movement, single-component, medium-modulus, low-VOC, UV-stable, non-sag polyurethane sealant.
