The air barrier test of a recently completed for the University of Washington project measured at .056 cfm/sf for an envelope area of 85,250 sf. The successful test was a […]

The roof to wall intersection is the junction where building aesthetics meets structural performance, air and moisture management, energy efficiency, construction trade sequencing, and operational maintenance. At such a critical […]

Today’s buildings face increasing complexity due to multi-layer assemblies, multiple trades, limited field training, tight schedules, and higher performance expectations, all within cost-sensitive projects. In contrast, earlier buildings were simpler, […]

In this course, we'll learn about the science behind thermal, air, and moisture control for steel stud construction. We'll interpret the code requirements for building envelope design and performance and […]

The presentation will review building enclosure assemblies that have experienced failures as well as building enclosure assembly designs that would have resulted in failures and the changes to the design […]

Air barrier requirements have been included in IECC and ASHRAE 90.1 for nearly two decades, but whole building airtightness testing has only recently become a code requirement in many jurisdictions. […]

Over the course of 14 years, Walsh Construction Company has been on a journey of learning and discovery regarding effective strategies to create airtight building enclosures. We have learned from […]
