Folks,

TF kit erected & roofing underway. I'm ready to start insulating this week & have a quick question. I have large porch areas to front & rear which I want to close in temporarily until PVC soffit & fascia is fitted (several months away). Would appreciate any feedback as to the most suitable type of board to fix to the underside of the trusses until such time as permanent cladding is in place. I was thinking of WPB or even marine, but given that the fix is termporary, would like the solution to be as cheap as possible. Thanks in advance, apple1
