Drained- and Rain-Screen cladding design has become commonplace over the last number of years, at least in many of our Northern-US practice areas. As a result, the industry has shifted much of its research and design effort to the further advancement of both the structural attachment methods for cladding and the improvement of the thermal properties of the attachment.
Air tightness testing is becoming more prominent in building codes across the country with an ever increasing focus on energy conservation and indoor air quality control. This presentation focuses on how to select and perform building airtightness tests.
Fluid applied membranes, whether as a flashing or as a weather resistive barrier, are becoming much more common in the marketplace.
In this course the presenter will discuss current research and understanding of moisture related problems within sloped roof attics in the Pacific Northwest. Case studies will be presented to illustrate the possible wetting sources in wood-frame construction along with practical solutions for mitigating the potential for problems in new construction.
