Q.How does foam insulation on framed walls affect moisture problems? A.In very cold climates, foam on the interior of a wall can work okay, since it serves as an interior vapor barrier. However, there is one important difference. Because of the high R-value of the foam, the wall cavity...
Class I vapor barrier: 0.1 perm or less Class II vapor retarder: 0.1 < perm <1.0 perm Class III vapor retarder: 1.0 < perm <10 perm Typically, builders place vapor barriers (like polyethylene) on the interior wall and ceiling insulation to prevent vapor diffusion into the wall systems durin...
However, if you carefully seal the warm-side vapor diffusion retarder and interior finish, you can also safely install a low-permeable material, such as rigid foam board insulation (a perm rating as high as 1.4), on the cold side of walls. A good rule-of-thumb: to prevent trapping any...
air does hold moisture in vapor form. Air and vapor barriers both stop the movement of vapor. However, only an air barrier prevents airflow. Above- and below-grade walls both require an air barrier. Using a vapor barrier on the interior side of framed walls may or may not be needed, ...
