Connecting two crawl spaces
I’m in the process of encapsulating and insulating two (currently) separate crawl spaces in my mid-60’s built home. One of the spaces is under part of the original house adjacent to a finished basement, the other is under an addition built sometime later. The two spaces are next to each other with only a small hole for a HVAC duct between them. My question is, should I cut a larger opening between them in order to allow better air circulation once they’re fully encapsulated?
