Eaves in non-vented attic
Our new home design will have a non-vented attic space, with the underside of the roof deck (between rafters) insulated with R-50 closed cell foam. The eaves will extend ~12″ from the rough-framed walls.
My question is how should the eave space be treated? Fill with spray foam after installing non-vented LP SmartSide soffits, fascia, etc.? Or, stop the roof deck insulation at the exterior wall sheathing plane and install vented LP SmartSide soffits?
