Insulating an Attached Garage
We are about to insulate an attached garage (no overhead building space, just a standing seam roof) and wanted to check-in on the best method. It’s 2″x6″ walls and 2″x10″ roof. We won’t probably heat it much at all except for occasionally, but we do want a conditioned and insulated space for working and storing root crops —- we’re in Vermont and our basement is heated (thus too warm for storing root crops). The exterior sheathing is ZIP. I was thinking to do blown-in cellulose, should I also try to put a rigid thermal barrier, also for better air-sealing? Any suggestions would be great, thank you!
