1875 attic insulation/ventilation dilemma
Currently in the process of replacing our old batt faced insulation with R-30 unfaced in the floor joists. Attic specs: 4 exterior windows – not gable vents 8 box vents one solar vent no soffit vents foam insulation was sprayed around the perimeter of the attic – where soffit vents would be placed new roof (september 2019) 75% of insulation as been installed – interior of attic has not been insulated yet. We are awaiting electrical work to be completed. Of the four attic windows, 2 are glass originals and closed; 2 are covered with louver shutters and screen – until new ones are installed. It snowed at the beginning of the week and the two windows iced up on the inside, indicating that there is too much moisture in the attic. The floor still needs to be airsealed in spots. Question: How should we address not having soffit vents? Can the windows be used even though they aren’t true ‘at the top’ gable windows? If we can use them, then how? Should I have used faced insulation? Will the new insulation lose R value if I have to lift it up to replace with faced? What is the best way to air leak seal? There are places that need sealed. Other consideration: Attic has walk up steps. The door that leads to the attic has insulation on the attic side. Any thoughts, insight, and suggestions?? Critiques? Ways to get the proper ventilation? Thank you!
