I need to run a 12' long 1 1/2" vent up slope in a cathedral ceiling. When completed there will be 14" of bat insulation above the drywall and another 4" of open space for roof venting above the insulation.
Am I best to run the vent line tight to the drywall, mid insulation or above the insulation.
TIA
