Someone suggested to lay 2x4's flat against cement wall every 24" and secure with adhesive and nail gun. then put 1.5" XPS rigid foam insulation in that 24" space against cement wall. Finally cover wall with 1/2" regular sheetrock. What about using pressure treated 2x4's? Would the chemicals cause more health issues?
