Thanks for the advice, I have some 3x2 and some 4x2 so will combine to fix to rafters and purlins. I can lay them flat so I get more surface area to screw boards to and more depth between the rafters. I just need it to be solid and safe I guess.
I’m trying to fit a barn ceiling For an office but have come a cropper.
I want to fit plasterboard between rafters but because I have installed celotex between them I have nothing to attach the boards to. My suggested option is to build a framework inside the rafters with timber.
