Quick question about my build…..
Bad weather, holiday and job hunting have taken priority so not much progress the last few weeks, plus I am not in a hurry so not beating myself up too much to finish. Timeline is Watertight before end of September.
Anyway I was trimming the joists for the rear overhang when I realised even though the frame is quite substantial and bolted to the concrete etc I was suprised at the amount of Flex when I was at roof level. I was hoping to put the first 18mm ply sheets on the roof but a bit concerned I would cause sme damage climbing on it. I had planned to fix the housewrap to the frame then batten and clad over that, then board the inside but I think I will put 12mm board on the outside just to stiffen it up. My plan now for the walls is:
12mm Ply inside, 2×4 frame (with insulation), 12mm board, batten, housewrap, Cedar cladding (Vertical)
Will this be OK or do I need another batten between the outer board and the housewrap?
Cheers
