Cape Cod built in 1939-40.
Mostly brick exterior.
Attic well insulated not overpacked.
Exterior walls mostly exterior brick, facing cinder block with,
~ 1" gap between block wall and interior composite wall of
proto-drywall and plaster - NO INSULATION.
1. With storm windows and the window frames well insulated; what benefit from installing new windows?
2. Besides cutting holes at the top of every stud bay and blowing in non-absorbent insulation, wrapping the interior or exterior, is there
something I'm missing?
