How to handle insulation on Cape Style House
I don't know if you are commenting on the original 3 month old post or asking for guidance......
The last link at "simplesavings" above covers it. Foamboard between joist bays, and air-seal it. Run the board up to cover the edge of f.g. batt in ceiling/wall joint at knee wall to prevent wind-washing. Leave room for your continuous baffles installed with 1" end gap as per manufacturer. No insulation under attic room unless garage/cold area below. Cover foamboard per local code possibly with 2" f.g.
Stuffing rolls of f.g would compress it (lose R-value) and still let the air through, which you want to stop...... or f.g. in a garbage bag and canned foam the gaps. Be sure to air seal around those wire/plumbing holes.
Clothes taking longer to dry?
Clean the dryer screen in HOT water if using fabric softener sheets.
They leave a residue that impedes air-flow, costing you money.
Clean the ducting in the last six months? 17,000 dryer fires annually!
