We live in an old 2x4 wall home that I’m told by the previous owners originally had no insulation, then it had loose fill cellulose insulation added decades ago between the studs, but as per usual the cellulose has settled and there are big gaps at the top. As part of an extensive home renovation we have decided to strip the walls inside and out, keep the structure but add insulation to the inside but also the outside of the walls so we don’t lose too much space inside. Do you have suggestions about how to go about this? I’ve read some of your pages about avoiding condensation and moisture in walls so I am fairly aware of the issues but still not confident in what is the best approach for exterior insulation on the walls during renovation, any advice on technique, materials or cost comparisons?
