Matt Risinger explains how new WRB offerings from Dorken - including Delta Fassade-SA and Delta Stratus-SA - address concerns about vapor permeability and UV resistance. Risinger builds in Texas, a hot and humid climate zone, and reminds viewers that permeability requirements for wall assemblies are different in colder climates. Viewers should be aware that this video is sponsored in part by Dorken Delta.
