The Decision to Air Seal or Vent a Walk-Up Attic
Hi All, I purchased a home built in 1927 in NY. I would like to finish the walk up attic. Im not sure if it should be vented or sealed.
Currently the only ventilation is 2 gable windows on either side and a dormer with windows. Per roofing contractor, due to their design the eaves do not allow air flow through them to the attic so soffit vents are out of the question. I am getting the roof replaced and the plan was to install a ridge vent thinking that this would help a little but I would still have to leave windows open for ventilation which I do not want to do. There is some batt insulation in the rafters. Most if it was torn down, maybe due to mold issues. No insulation in the floor. There are ducts from a mr slim to send heat or ac to the floor below.
Id like the walk up attic to be another room with a comfortable temp and humidity all year round. What do you think would be the best way to achieve this? Air seal everything and forget the ridge vent? Or try to vent?
