We are neck deep in a renovation right now and the house is nearly gutted. It's more of a camp right now to be honest. We are considering insulating the ceiling on the first floor to make the house more quiet. I feel like this would prevent heat from moving upstairs. The stairwell itself is on the north side of the house and stays 5-10 degrees cooler than the rest of the house. I can't tell if this means there is an active draft of cool air coming down and hot air rising up or if it just stays stagnant and cold. As it stands now our bedroom, bathroom, and second bedroom are upstairs and the kitchen and living areas are downstairs and open concept. I have attached a hasty layout.
