First time homeowner here! Recently purchased a large farmhouse style home from 1852. In the process of finishing the attic and I've run across my first major hurtle. I naively bought R19 rolls and put them in the rafter bays. I had to do 2x per bay because my house has 30 inch rafter spacing. The bays are only 8 inch deep so I thought r30 would be too thick.
The space has knee walls and a small ceiling on the top.
Now for the major problems.
I have 2x gable vents and no ridge vent.
Where my rafters meet the wall of the house there is basically a squared off tree, too hard to put soffet vents in.
However right below where the rafter meets the wall, there is a 3 foot wall before the floor/ joists.
Can I install some sort of vent through the siding maybee 2-3 and get fresh air into the insulated knee wall area? Will that provide sufficient airflow up to the ceiling area?
Will gable vents be ok for now? roof has about 5-8 years of life left and I don't want to tear into it yet?
Or will this setup no help with insulation purposes all that much?
Thanks for the help in advance!
