This is my third winter in our 1956 ranch home in Lawrence, KS. The first really cold day of each year I wake up to all my windows being fogged over on the inside, and condensation (wet spots) on the ceilings of several rooms where the ceiling and exterior walls meet. My attic is very hot in the summer and has very little insulation (blown in paper)without a vapor barrier. My main question is if the current insulation needs to be shoveled out and replaced with a lot more insulation with a vapor barrier. Or is there something else that is causing my problems?
