Poorly detailed and designed parapets can lead to significant building degradation if not monitored. To enhance the quality and longevity of this critical juncture, there are a few specific design […]

Clear documentation can facilitate the coordination and leverage the unique expertise of each team member. We will highlight common oversights or omissions in design drawings, specifications, and construction of air […]

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. […]

Properly designed and installed through-wall flashings and transition membranes are critical components of a durable and effective building enclosure. This presentation provides a detailed overview of the challenges and solutions […]

Today's buildings are more complex than ever, incorporating multiple layers of materials, numerous trades, tighter schedules, higher performance expectations, and greater cost sensitivity. Unlike the simpler building systems of the […]

Today’s construction projects incorporate hundreds—if not thousands—of materials and products within the building enclosure. Among the most critical, yet often overlooked, components is flashing. Commonly referred to as “that little […]

Drip edges have been in use for centuries, but we often take their quiet contribution to building performance for granted. While some designers resist using them due to their aesthetic […]

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 […]
