Hi all, I am converting my integral double garage to a workshop. I intend to erect a stud work wall just behind the up and over door (about 150 mm in from the door) by fixing rigid insulation panels to the back of the stud work (between stud work and up and over door), fill between the noggins with rockwool and face the wall with 18 mm ply wood. My question is how can I fix the Rigid insulation panels to the back of the stud wall using a method that can be undone easily (as opposed to grab fix) if I need to convert the workshop back to a garage? All constructive suggestions welcome
