Concerns regarding moisture control performance can affect walls of any thickness, with or without the added protection of exterior continuous insulation. One purpose of this Research Report is to present data to evaluate and substantiate an appropriate application of continuous insulation in an R20+5 assembly (e.g., R20 cavity insulation plus R-5 continuous insulation on the exterior). The data and engineering principles used herein are broadly applicable and also may be used to establish appropriate prescriptive guidelines and limitations for a wider variety of wall assemblies and materials.
