I am currently researching using icynene spray foam insulation for the upstairs of my cape cod. The level is currently unfinished and will house a bedroom and bathroom.
I have been told no ridge vents or other ventilation is needed, and others say spray the foam then install a ridge vent for moisture control and ventilation.
Do I need additional ventilation with a spray in insulation? If so, what should I plan on getting into?
