Title: Hybrid Wall Construction and Quality Control Issues in Wyandotte, Michigan

This report is the second report on the Wyandotte Neighborhood Stabilization Program 2 project in Wyandotte, MI, and documents refinements to the design, construction, and quality control for the high R-value enclosure. The report will be of interest to designers and builders of production housing in Cold Climates. The focus of the second round of research was on using the hybrid insulation approach to develop a reliable method of achieving consistently low airtightness numbers. There are two primary outcomes from this research. First, the airtightness measurements demonstrate that with a shallow learning curve, even new builders entering the program having little experience with the technology package are able to achieve consistent results that are less than 1.5 ACH50. Second, the process changes implemented to help secure these results were straightforward and ended up encouraging better communication between designer, builder, and the city officials supervising the project.
