If you cut them accurately you can just squeeze/push/tap them in and they will self support. Horrible things to cut though.Oi oi - thats exactly what I want to do with my Barn/workshop in the very near future
Got a pile of 150mm Celotex seconds waiting to go in between the purlins. They are 6x2 set about 5ft apart.
Was thinking of stuffing them up there and covering with OSB or thin ply......
