Retrofit insulation in attic slanted roof section with no soffit vents
I have an 1850s 1 and 1/2 story New England farm house. The upstairs bedrooms all have a partially slanted ceiling that is uninsulated. There are no soffit vents and I want to just fill the whole slanted part with insulation. Will that be a problem? Also I did lay in loose cellulose insulation on the flat part of the attic on top of plastic sheeting. Was that wrong to put the plastic down first?
