I have a 24′ x 35′ attic that has roof going all the way to floor but with steep pitch. I have t&g ply for the floors, but I am wondering about futureproofing. I will have approximately 4′ knee walls making about 3′ of floor space between soffits and knee wall. Should ply go all the way to the soffit? Or can I leave some insulation exposed for easier underfloor wiring? What’s the best practice here?
