Hello, I am thinking about converting my 20x10ft concrete panel garage into space for my daughter and her partner to stay over in when they visit, also a office space. My question is, would it be possible to insulate inside and outside the concrete panels of the garage or will this create problems later on with damp or condensation. My reason for this is to save on space on the inside, 50mm inside and 50mm on the outside. I would finish the outside with featherboard or composite panels over the top of the insulation. Also, would the exterior insulation need a gap for airflow, or could it be fixed directly onto the panels? I appreciate an advice
