AbstractThis paper presents an extension of the cup methods in which a series of dry cupand another series of wet cup measurements are suggested at varying relative-humidity levels outside the cup. Also, a detailed procedure for the data analyses to define the dependence of vapor permeability onrelative humidity is presented. The methodology is applied successfullyto three materials: perlite insulation board, calcium silicate insulationboard, and plywood sheathing.
