Concrete construction insulation retrofit question
I live near Baltimore, MD in zone 4A. My house is a single story rancher constructed of concrete block with a painted brick exterior and plaster interior walls. I purchased it last June and have been trying to improve the efficiency and comfort of the house since. I replaced the lead paint covered casement windows with vinyl replacement windows, I had 18 in. of loose fill fiberglass insulation blown into the attic and I have weatherstripped and air sealed as much as I know how. The house is still cold feeling in the winter due to the unisulated exterior walls radiating cold into the room.
I have been reading on retrofiting insulation into the wall cavitites and the various pros and cons of spray foam vs. other blown in materials. Having a concrete constructed house vs. a wood frame seems to create other issues with moisture. I am trying to find out what the correct method of insulating the interior walls is or if this is even a good idea due to the construction of my home. I would appreciate any advice that can be provided.
