Mastering Modern EIFS with Stone Wool Insulation | Passive House Component Spotlight

Since 1969, EIFS has been a cost effective tool to address continuous insulation needs on buildings throughout North America. As demand for high performance low energy buildings has grown, so to has the use of EIFS on buildings throughout the US and Canada, often incorporating foam plastic insulation. Alternatively, EIFS incorporating high density stone wool insulation is gaining momentum in North America and is an approach that has been commonplace in Europe for years. With fire safety top of mind these days, North American codes and standards are changing, requiring more fire resilient wall assemblies, leading to the adoption of stone wool EIFS solutions in areas like NYC, California, and beyond. In the Passive House world, factors such as lower embodied carbon and resiliency has further pushed the adoption of this approach. In this program, we cover strategies for designing and installing Exterior Insulation and Finish Systems (EIFS) with stone wool exterior continuous insulation. We also dive into multiple passive house case studies that have utilized stone wool EIFS to address their performance requirements.
