Exterior rigid insulation for attached garage?
I am building a house in 6A/7A. I am going with 3 inches of EPS exterior ridged foam and dense pack in the walls. My question is… I will have a heated 3ish stall garage attached to the house. It covers part of the front and one whole side. I originally decided to put exterior insulation around the garage but now rethinking it. Is the cost and complexity of the exterior insulation worth it for a garage (garage doors, windows, exterior doors)? It will be heated on average around 40 degrees Fahrenheit (4 Celsius) most of the winter. With garage doors and vehicles going in and out… thermal bridging is not a major source of heat loss. Or am I off pace and put exterior insulation on? Let me know your thoughts. Thanks
