What is the best insulation for basement concrete walls?
...indows open and dehumidifyer on. The walls do not sweat.. The humidity in summer is rarely below 80. I am in Northern VT and the temp now is 58 in the basement and humid 63. I have not seen any mold yet. Spray foam out - toxic. So are some rigid foam boards. Family very concerned. You mention a new type of friendly boa...
