When my house was built it had an attached garage. As a lot of people do I removed the garage door and framed it in. I am getting ready to raise the floor up even with the floor in the rest of the house for more efficient heating because the concrete lets off a lot of cold air in the winter. My question is, do I need to insulate the raised floor or will that make the floor sweat when the concrete below it is cold and the air in the house is warm causing mold or other problems?
Thank You for any possible help.
