Description
Interior insulation retrofit generally leads to wetter and colder masonry conditions in cold climates, increasing the risk of freeze-thaw decay. This session will present the physics behind various mechanisms affecting freeze-thaw decay and how risks of decay can be assessed/avoided, including the number of assessment case studies for projects with differing budgets and importance. A field review of the most basic assessment is where existing conditions and exposure issues can be identified, setting a basis for retrofit recommendations. Next, coupled field review with masonry testing and hygrothermal analysis to predict the impacts of various retrofit insulation assembly options on decay is recommended for higher-value projects that justify greater diligence. For a critically important project, there is ample justification to also provide mocked-up retrofit wall assembly conditions and rain exposure monitoring for assessment confidence and direct field trialing. Finally, different available retrofit approaches for these projects—including handling interfaces with foundations, floors, and openings—and their respective heat, air, and moisture control performance will be presented and discussed.

Learning Objectives

1. Describe the effect of interior thermal insulation on masonry conditions.
2. List various mechanisms that cause masonry freeze-thaw decay.
3. Explain suitable risk decay assessment approaches for a range of retrofit projects.
4. Discuss effective thermal performance when interior insulation as a retrofit for old, heavy masonry buildings.
