IIBEC PSC Lunch and Learn July 10, 2025
Designing Walls for
Control of Air, Water, Thermal & Vapor
Summary:
Review a variety of building types and discuss the continuity of detailing required to manage moisture, air, vapor, and thermal performance, as well as wind resistance requirements at the critical wall-to-roof interface. You will be provided guidelines to successfully navigate these often competing interests and provide strategies for achievable performance through design and specification without compromising the aesthetics with distracting details for commercial building wall systems.
This presentation discusses the impacts of whole building performance, design requirements, material & assembly requirements, and installation verification requirements during construction.
Learning Objectives:
• Discuss the requirements to manage moisture, air, vapor, and thermal continuity.
• Recognize the changing building and energy codes, and their interaction across building enclosure system interfaces.
• Apply specific examples and air barrier systems to current and future project designs.
• Outline design and specification requirements to set performance requirements for wall systems.
