Just recently bought an 1837 farmhouse and although handy I have not much experience with this age house. Previous owners have cemented the inside of two of the exterior walls of the kitchen from floor to ceiling and used sheathing and paneling to cover. I am gutting the kitchen and doing a complete makeover and concerned about the insulation factor. I am thinking I should leave the concrete, stud out the walls, then insulation and drywall. Does anyone think any different? Should there be a vapor barrier? Is it vital to remove the concrete? Any other suggestions? Any help will be much appreciated.
