Does anyone know anything about adding insulation to exterior and/or interior walls of a mid 90's stick built home?
We added a bunch of blow-in insulation in the attic when we first moved in. Now we're convinced we need to do some or all of the walls as we have several rooms in our house that aren't keeping up with the HVAC, particularly on the second floor. Very cold in the winter and hot in the summer.
Based on a brief search, it seems injected foam insulation is the way to go.
Anyone have any experience with this or any other method?
