Roof-insulation Retrofit, Codes for Existing Buildings, and Air-sealing Tape Choices The Fine Homebuilding Podcast

Patrick, Kiley, and Matt start the show with more feedback about cool stuff people find in old walls before getting schooled by an infrared-camera expert on the phenomenon of emissivity and how it skewed their beer-koozie experiment. Then it's on to questions about building gable-end roof extensions for an insulation retrofit, why there's a separate code for old buildings (and whether or not anyone even uses it), how to make an attached garage part of a home's conditioned space, and options for attractive gutters when there's a tight budget.
