The Three Categories of WRBs
The building code requires the use of a WRB, or water-resistive barrier, in drained walls. There are three categories of WRB: (1) mechanically attached membranes, (2) self-adhered and fluid membranes, and (3) integral sheathing plus water and air control materials. This short presentation reviews how these membranes manage water and air differently and discusses the constraints associated with each that might make one category of membrane more appealing than another in the context of a particular project.
