Fixing insulation boards to studwork

[davidebt]

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

Screws and tape the joints (gaffa will do)

Will screws hold in insulation boards - they are only foil coated?

Thanks for response but all these fixings are designed to be used from the side of the insulating board that you have access to! I will have no access to the face of the boards but will need to pull them up tight to the stud work from the stud work side.

How are you getting the board on the other side if you don't have access?

Then you are building it wrong. Foil insulation is more efficient on the room side to reflect the heat back into the room.

If you still want to do it that way, then you need to build the frame on the floor, insulate it and then put it in place.
