Hi
Having given into the need to board my loft please advise re my thoughts as to the best way forward
there are 2 4by2 timbers running north/south with 4by2 timbers at equal spacing running east/west below them
Given that the target depth for insulation is now 8inches, I was thinking of adding extra 4by2 timbers laid on top of the existing east/west timbers then adding extra insulation (Mineral fibre or fibreglass matting )then boarding.
What is the best method for attaching these extra timbers?
At the eaves how much air gap should I allow? One thought is to hold the insulation back with thin plywood tacked to the trusses (shaped to fit down to the ceiling.
