Designing Wall Systems for Specific Climate Zones
Presenters: John Posenecker, PE – Senior Principal, Senior Engineering Consultant, Building Enclosure Practice Lead, Terracon & Kayla Maines, AIA, Senior Architect, Terracon Consultants, Inc
Copying and pasting a wall or roof assembly that works in one part of our country into a project in another part of the country could be not just problematic, but potentially catastrophic. This presentation will use data and hygrothermal modeling to articulate what happens when tried and true assemblies from one part of the country get moved to a very different climate. More importantly, we’ll cover strategies to mitigate these issues. While many may be familiar with a Class I Vapor Retarder (“vapor barrier”) in the wrong part of an assembly, we’ll also cover the impacts of insulation type, the overreaction to perm ratings, light-colored roofing membranes, and reservoir claddings such as stucco and unit masonry.
